PRA remote IO SCANNING using Schneider eco structure control expert platform

PRA Remote IO Scanning Using Schneider EcoStruxure Control Expert

Introduction

In modern industrial automation, Remote I/O (RIO) Scanning plays a crucial role in optimizing system performance by enabling communication between a Programmable Logic Controller (PLC) and remote I/O modules. Schneider Electric's EcoStruxure Control Expert (formerly Unity Pro) provides powerful tools to configure and manage PRA (Process Remote Automation) Remote I/O Scanning for efficient and seamless data exchange.

This article explores the step-by-step process of setting up PRA Remote I/O Scanning using Schneider’s EcoStruxure Control Expert and highlights key configurations for ensuring smooth communication.


Understanding PRA Remote IO Scanning

Remote I/O scanning allows a PLC to communicate with distributed I/O modules over a network, reducing wiring complexity and improving flexibility. This is essential for large-scale industrial applications where I/O devices are spread across different locations.

With Schneider Electric’s PRA Remote I/O Scanning, the PLC continuously reads inputs and writes outputs to remote I/O devices over a communication protocol such as Ethernet/IP, Modbus TCP, or CANopen.


Step-by-Step Configuration in EcoStruxure Control Expert

Step 1: Open EcoStruxure Control Expert & Create a New Project

  1. Launch EcoStruxure Control Expert.
  2. Select your Schneider Electric PLC model (e.g., Modicon M580, M340).
  3. Create a new project and configure the hardware settings.

Step 2: Configure the PLC for Remote I/O Communication

  1. Open the Hardware Configuration Tab

    • Navigate to the "Configuration" section.
    • Select the PLC backplane and configure the CPU.

  2. Add an Ethernet Network Module

    • Right-click on the CPU rack and add an Ethernet module (e.g., BMXNOC0401 for M340 or BME NOC 0311 for M580).
    • Configure the IP Address, Subnet Mask, and Gateway for the Ethernet module.

Step 3: Adding and Configuring the Remote I/O Scanner

  1. Open the DTM Browser

    • In EcoStruxure Control Expert, go to "DTM Browser" and add a new Remote I/O scanner under the Ethernet module.

  2. Define Remote I/O Device Settings

    • Assign a device name and set the IP address of the Remote I/O module.
    • Ensure that the network settings match the PLC’s Ethernet configuration.

  3. Scan and Detect Remote I/O Modules

    • Click "Scan Devices" to detect the connected Remote I/O modules.
    • The system will automatically list the available PRA remote I/O devices.

Step 4: Configuring Remote I/O Modules

  1. Assign I/O Modules to the Remote I/O Scanner

    • Select the PRA Remote I/O module (e.g., BMXCRA31210, BMXDDI3202) from the device list.
    • Define input and output mappings.
    • Set up any required diagnostics and alarms for real-time monitoring.

  2. Validate the I/O Mapping

    • Check the status of connected I/O devices.
    • Ensure that all input and output addresses are correctly assigned.

Step 5: Program and Test the I/O Scanning

  1. Write a Simple Ladder Logic Program

    • Create a basic Ladder Logic or Structured Text program to test the remote I/O.
    • Example: A digital input from a remote module turns on a digital output in the PLC.

  2. Build and Transfer the Project to the PLC

    • Compile the project and download it to the PLC.
    • Switch the PLC to RUN Mode.

  3. Monitor I/O Status

    • Open the EcoStruxure Control Expert Online Mode to view real-time I/O updates.
    • Verify that the remote I/O signals are functioning as expected.

Troubleshooting Tips

  • Communication Failure: Check the Ethernet cable, IP configuration, and firewall settings.
  • I/O Not Updating: Ensure that I/O modules are correctly mapped in the Remote I/O Scanner.
  • PLC Not Detecting Remote I/O: Perform a hardware scan and ensure the correct firmware version is installed.

Conclusion

Configuring PRA Remote I/O Scanning in Schneider EcoStruxure Control Expert allows seamless data exchange between a PLC and remote I/O devices, enabling efficient and reliable industrial automation. By following the step-by-step setup, industries can enhance their control systems, reduce wiring costs, and improve real-time monitoring of field devices.

Scheider ATV 320 drive communication with Schneider PLC M 340 using control expert

 To establish communication between a Schneider ATV320 drive and an M340 PLC using Control Expert (formerly Unity Pro), follow these steps:

Hardware Setup: Connect the ATV320 to the M340 PLC using Modbus RTU (RS485) or Modbus TCP/IP (Ethernet) based on the available communication options. Ensure proper wiring, IP addressing (for Ethernet), or serial communication parameters (for RS485). ATV320 Configuration: Configure communication settings (Modbus address, baud rate, parity, or IP address) via the drive's keypad, SoMove software, or Web Server. Set the control mode to enable network control. M340 PLC Configuration in Control Expert: Create a new project and configure the communication module (e.g., BMXNOC for Ethernet or serial communication modules for RS485). Define the ATV320 as a Modbus device (Slave for RTU or TCP/IP). Control and Monitoring Setup: Map the required Modbus registers for control (start/stop, speed setpoint) and feedback (status, frequency). Use READ_VAR and WRITE_VAR functions or Schneider’s prebuilt DFBs (Derived Function Blocks) for communication logic. Testing and Validation: Verify communication using diagnostic tools in Control Expert. Test the control and feedback by sending commands to the drive and reading its status.
