Each controller comes with a certain amount of embedded I/O, which is physically located on the controller. The controller also allows for adding expansion I/O. This section discusses the following I/O functions: • Embedded I/O on page 2 • MicroLogix 1400 Expansion I/O on page 2 • MicroLogix 1400 Expansion I/O Memory Mapping on page 3 • I/O Addressing on page 11 • I/O Forcing on page 12 • Input Filtering on page 13 • Latching Inputs on page 15Rockwell Automation Publication 1766-RM001G-EN-P - March 2017 1 Chapter 1 I/O ConfigurationEmbedded I/O The MicroLogix 1400 provide discrete I/O and analog input that is built into the controller as listed in the following table. These I/O points are referred to as Embedded I/O. AC embedded inputs have fixed input filters. DC embedded inputs have configurable input filters for a number of special functions that can be used in your application. These are: high-speed counting, event input interrupts, and latching inputs. The 1766-L32BXB and 1766-L32BXBA have three high-speed outputs for use as pulse train output (PTO) and/or pulse width modulation (PWM) outputs. MicroLogix 1400 Expansion I/O If the application requires more I/O than the controller provides, you can attach I/O modules. These additional modules are called expansion I/O. Expansion I/O Modules For the MicroLogix 1400, Bulletin 1762 expansion I/O is used to provide discrete and analog inputs and outputs, and specialty modules. You can attach up to seven expansion I/O modules in any combination. MicroLogix 1400 Embedded I/O Catalog Number Description Input Power User Power Embedded Discrete I/O Embedded Analog I/O Comm.

Input Forcing When an input is forced, the value in the input data file is set to a user-defined state. For discrete inputs, you can force an input “on” or “off ”. When an input is forced, it no longer reflects the state of the physical input or the input LCD indicator. For embedded inputs, the controller reacts as if the force is applied to the physical input terminal. Output Forcing When an output is forced, the controller overrides the status of the control program, and sets the output to the user-defined state. Discrete outputs can be forced “on” or “off ”. The value in the output file is unaffected by the force. It maintains the state determined by the logic in the control program. However, the state of the physical output and the output LCD indicator will be set to the forced state.

There are five terminals assigned to the input channels that provide four voltage inputs, and a return signal (commons). The following table shows sample Analog Signal and Data Word values using the nominal transfer function formula: N=Vin x 4095/10 where Vin (analog signal) is in volts (V) Converting Analog Input Data Analog inputs convert voltage signals into 12-bit values. To determine an approximate voltage that an input value represents, use the equation shown. For example, if an input value of 1200 is in the input image, the calculated value is as follows: Analog Outputs The MicroLogix 1400 -L32BWAA, -L32AWAA, and -L32BXBA support 2-channel, 12-bit resolution analog output. These channels have 0…10V DC output range. Output words 4 and 5 contain the value of analog outputs (Word 4 : analog output channel 0, Word 5 : analog output channel 1). Latching Inputs Converting Analog Output Value to Actual Output Voltage Analog outputs convert voltage signals into 12-bit values. To determine an approximate voltage that an output value represents, use the equation shown.

A latching input is an input that captures a very fast pulse and holds it for a single controller scan. The pulse width that can be captured is dependent upon the input filtering selected for that input. The following inputs can be configured as latching inputs: Enable this feature using RSLogix 500/RSLogix Micro. With an open project: 1. Open the Controller folder. 2. Open the I/O Configuration folder. 3. Open slot 0 (controller). 4. Select the Embedded I/O Configuration tab. 5. Select the mask bits for the inputs that you want to operate as latching inputs. 6. Select the state for the latching inputs. The controller can detect both “on” (rising edge) and “off ” (falling edge) pulses, depending upon the configuration selected in the programming software. The following information is provided for a controller looking for an “on” pulse. When an external signal is detected “on”, the controller “latches” this event. In general, at the next input scan following this event, the input image point is turned “on” and remains “on” for the next controller scan. It is then set to “off ” at the next input scan. The following figures help demonstrate this.

Falling edge behavior operates exactly the same way with these exceptions: • The detection is on the “falling edge” of the external input. • The input image is normally “on” (1), and changes to “off ” (0) for one scan. TIP The “gray” area of the Latched Status waveform is the input filter delay. IMPORTANT The input file value does not represent the external input when the input is configured for latching behavior. When configured for rising edge behavior, the input file value is normally “off” (“on” for 1 scan when a rising edge pulse is detected).

This situation can occur when an application needs to be updated, but the data that is relevant to the installation needs to remain intact. This capability is referred to as Data File Download Protection. The protection feature operates when: • A User Program is downloaded via programming software • A User Program is downloaded from a Memory Module Setting Download File Protection Download File Protection can be applied to the following data file types: • Output (O) • Input (I) • Binary (B) • Timer (T) • Counter (C) • Control (R) • Integer (N) • Floating Point (F) • String (ST) • ASCII (A) • Long Word (L) • Proportional Integral Derivative (PD) • Message (MG) • Programmable Limit Switch (PLS) • Routing Information (RI) • Extended Routing Information (RIX) • Recipe (Series B only) User Program Transfer Requirements Data File Download Protection only operates when the following conditions are met during a User Program or Memory Module download to the controller: • The controller contains protected data files. • The program being downloaded has the same number of protected data files as the program currently in the controller. • All protected data file numbers, types, and sizes (number of elements) currently in the controller exactly match that of the program being downloaded to the controller. TIP The data in the Status File cannot be protected.Rockwell Automation Publication 1766-RM001G-EN-P - March 2017 27 Chapter 2 Controller Memory and File TypesAccess the Static File Protect feature using RSLogix 500/RSLogix Micro programming software. For each data file you want protected, select the Static protection in the Data File Properties screen as shown in this illustration. To access this screen, right mouse click on the desired data file. Program Password Protection Programming software access to MicroLogix programs and controllers can be restricted through password protection. Each controller program may contain two passwords, the Password and the Master Password. (The Master Password is ignored unless a Password has also been configured.) The Master Password takes precedence over the Password. That way, all controllers on an assembly line, for instance, can each have a different Password, but have the same Master Password, allowing access to all controllers for supervisory or maintenance purposes. MicroLogix 1400 controllers also have a third password, the Subroutine Protection Password. This password can be configured to restrict viewing of selected ladder files. By default, no passwords are configured in the controller. You can create, change or delete a password using the Controller Properties dialog box. Unencrypted IMPORTANT Starting with RSLogix 500/Micro version 8.40, these passwords may optionally be encrypted so that as they are transmitted between the controller and PCs running RSLogix 500/Micro, someone with physical access to the network where communications is occurring over will not be able to "sniff" the network and capture the password(s). Even so, password protection should not be solely relied upon to prevent unintended changes to the program and data table. Refer to other sections in this chapter for additional steps that you may be able to take with your specific MicroLogix controller to prevent unintended changes.30 Rockwell Automation Publication 1766-RM001G-EN-P - March 2017 Controller Memory and File Types Chapter 2passwords consist of up to 10 numeric characters (0…9). Encrypted passwords contain at least one non-numeric character. Once a Password has been created and downloaded into the controller, any time the user attempts to open that offline file or go online with that controller, they will be prompted to provide either the Password or the Master Password before the software proceeds. If a password is lost or forgotten, there is no way to bypass the password to recover the program. The only option is to clear the controller's memory. If a memory module is installed, the user program has the "Load Always" functionality enabled and the user program is password protected, then the controller compares the passwords before transferring the user program from the memory module to the controller. If the passwords do not match, the user program is not transferred and the Program Mismatch bit (S:5/9) is set. TIP If a password is lost or forgotten, there is no way to bypass the password to recover the program. The only option is to clear the controller memory. See Clearing the Controller Memory on page 34.Rockwell Automation Publication 1766-RM001G-EN-P - March 2017 31 Chapter 2 Controller Memory and File TypesProgram Password Protection for Series B (Enhanced Password Security) RSLogix 500 version 11.00.00 or higher access to MicroLogix 1400 Series B (Enhanced Password Security) programs and controllers can be restricted through online password protection. Each Series B (Enhanced Password Security) program contains one password which can be set/change/clear when program is online with controller. Series B (Enhanced Password Security) programs also have a second password, the Subroutine Protection Password similar to Series A and Series B program. This password can be set, changed, or cleared offline or when the program is online with the controller. This password can be configured to restrict the viewing of selected ladder files whether online or offline. By default, no passwords are configured in the controller. You can create, change or delete a password using the Controller properties dialog box. The length of the Password should be 8 to 32 and it can contain the combination of integers (0-9), alphabets (upper and lower cases) and symbols (valid symbols are `~!@#$%^&*()-_=+[{]}\\|;:'\",<.>/?). The length of the Subroutine Protection Password should be 1 to 8 characters. It must contain at least one letter (upper or lower case) and can contain integers. IMPORTANT Master Password is not available in Series B (Enhanced Password Security) programs. LCD configuration changes are protected by a separate LCD password. For more information,on LCD Password Setup, refer to the MicroLogix 1400 Programmable Controllers User Manual, publication 1766-UM001. 32 Rockwell Automation Publication 1766-RM001G-EN-P - March 2017 Controller Memory and File Types Chapter 2Web View Disable This allows selective disabling individual Data Files from Web View.

The chapter is organized as follows: • Overview on page 37 • Real-Time Clock Function File on page 38 • Memory Module Information Function File on page 42 • Base Hardware Information Function File on page 44 • Communications Status File on page 45 • Ethernet Communications Status File on page 60 • Input/Output Status File on page 67 Overview Function Files are one of the three primary file structures within the MicroLogix 1400 controller (Program Files and Data Files are the others). Function Files provide an efficient and logical interface to controller resources. Controller resources are resident (permanent) features such as the Real-Time Clock and High-Speed Counter. The features are available to the control program through either instructions that are dedicated to a specific function file, or via standard instructions such as MOV and ADD. The Function File types are: File Name File Identifier File Description High-Speed Counter HSC This file type is associated with the High-Speed Counter function. See Using the High-Speed Counter and Programmable Limit Switch on page 77 for more information. Extended Pulse Train Output PTOX This file type is associated with the Pulse Train Output Instruction. See Pulse Train Outputs (PTOX) Function File on page 115 for more information. Extended Pulse Width Modulation PWMX This file type is associated with the Pulse Width Modulation instruction. See Pulse Width Modulation (PWMX) Function File on page 129 for more information. Selectable Timed Interrupt STI This file type is associated with the Selectable Timed Interrupt function. See Using the Selectable Timed Interrupt (STI) Function File on page 272 for more information. Event Input Interrupt EII This file type is associated with the Event Input Interrupt instruction. See Using the Event Input Interrupt (EII) Function File on page 276 for more information. Real-Time Clock RTC This file type is associated with the Real-Time Clock (time of day) function. See Real-Time Clock Function File on page 38 for more information. Memory Module Information MMI This file type contains information about the Memory Module. See Memory Module Information Function File on page 42 for more information. Base Hardware Information BHI This file type contains information about the controller’s hardware. See Base Hardware Information Function File on page 44 for the file structure. Communications Status File for Channel 0 CS0 This file type contains information about the Communications with the controller. See Communications Status File on page 45 for the file structure. Communications Status File for Channel 2 CS2Rockwell Automation Publication 1766-RM001G-EN-P - March 2017 37 Chapter 3 Function FilesRTC Battery Operation The real-time clock uses the same replaceable battery that the controller uses. The RTC Function File features a battery low indicator bit (RTC:0/BL), which shows the status of the replacement battery. When the battery is low, the indicator bit is set (1). This means that the battery wire connector could be disconnected or if the battery is connected, the battery may be ready to fail in the next two weeks. In the latter case, the replacement battery needs to be replaced with a new one. When the battery low indicator bit is clear (0), the battery level is acceptable. RTA - Real Time Clock Adjust Instruction Instruction Type: output The RTA instruction is used to synchronize the controllers Real-Time Clock (RTC) with an external source. The RTA instruction will adjust the RTC to the nearest minute. The RTA instruction adjusts the RTC based on the value of the RTC Seconds as described below. RTA is set: • If RTC Seconds are less than 30, then RTC Seconds is reset to 0. Real-Time Clock Accuracy at Various Temperatures Ambient Temperature Accuracy(1) (1) These numbers are worst case values over a 31 day month. 0°C (+32°F) -13…-121 seconds/month +25°C (+77°F) +54…-54 seconds/month +40°C (+104°F) +29…-78 seconds/month +55°C (+131°F) -43…-150 seconds/month ATTENTION: Operating with a low battery indication for more than 14 days may result in invalid RTC data if power is removed from the controller. RTA Real Time Clock Adjust Execution Time for the RTA Instruction Controller When Rung Is: True False MicroLogix 1400 999.8510 µs 0.4090 µs IMPORTANT The RTA instruction will only change the RTC when the RTA rung is evaluated true, after it was previously false (false-to-true transition). The RTA instruction will have no effect if the rung is always true or false.40 Rockwell Automation Publication 1766-RM001G-EN-P - March 2017 Function Files Chapter 3• If RTC Seconds are greater than or equal to 30, then the RTC Minutes are incremented by 1 and RTC Seconds are reset to 0. The following conditions cause the RTA instruction to have no effect on the RTC data: • RTC is disabled • An external (via communications) message to the RTC is in progress when the RTA instruction is executed. (External communications to the RTC takes precedence over the RTA instruction.) To re-activate the RTA instruction, the RTA rung must become false, and then true. TIP There is only one internal storage bit allocated in the system for this instruction. Do not use more than one RTA instruction in your program. TIP You can also use a MSG instruction to write RTC data from one controller to another to synchronize time. To send (write) RTC data, use RTC:0 as the source and the destination.Rockwell Automation Publication 1766-RM001G-EN-P - March 2017 41 Chapter 3 Function FilesMemory Module Information Function File The controller has a Memory Module Information (MMI) File which is updated with data from the attached memory module. At power-up or on detection of a memory module being inserted, the catalog number, series, revision, and type are identified and written to the MMI file in the user program. If a memory module is not attached, zeros are written to the MMI file. The memory module function file programming screen is shown below: The parameters and their valid ranges are shown in the table below. FT - Functionality Type The LSB of this word identifies the type of module installed: • 1 = Memory Module (MM1) MP - Module Present The MP (Module Present) bit can be used in the user program to determine when a memory module is present on the controller.
