Schneider Electric 140CRP31200 Overview

The remote EIO head module 140CRP31200 is manufactured by Schneider Electric for use as the head module on a local Quantum EIO installation. What task does the EIO head module perform on the local rack? The Modicon 140CRP31200 head EIO module allows the PLC to communicate with an Ethernet network and enable control of remote I/O devices. These products are manufactured in France and are designed for Material handling, packaging, and textile machines usage. They come with a 2-year warranty from MRO Electric. We also carry I/O Modules from other manufacturers such as Modicon and ABB.

Features of the 140CRP31200

The external Features of the Modicon 140CRP31200 head EIO module are an LED, a service port, and interlink port, a device network port, and a second device network port.  The LED is on the top front of the module.  Directly under LED I the service port (ETH1) followed by the interlink port (ETH 2). Below are the ETH 3 and ETH 4 device network ports. In order to keep the device running best, use the port stopper when the connections are not in use.

These ports allow for diagnostics of the ports and give access to external tools and devices. They provide connectivity to other Quantum EIOs, and they allow for I/O communication.

The primary function of the Modicon 140CRP31200 is to provide I/O scanning services. The I/O scanning services are meant for remote I/O devices. The I/O devices can be on a remote I/O network or a device network that has remote I/O and distributed I/O devices. The EIO head module uses a daisy chain loop topology to manage the remote I/O network. The Modicon 140CRP31200 is connected to a remote I/O network main ring.

Other Ethernet services can also be executed by the Modicon 140CRP31200. It can perform diagnostic functions as well as configuration for remote I/O devices.

Which function blocks can be used with the Modicon 140CRP31200? The four function blocks used with the 140CRP31200 are the IU_ERIO, DROP, and the XDROP.

Each local rack can only have one 140CRP31200 configured on it as it has interfaces that communicate with the Ethernet remote I/O devices on the network.

All of the modules that are on the Ethernet remote I/O can communicate with the PLC on the Ethernet network through the 140CRP31200 EIO head module which is able to make determinations about the exchange between them.  


The task of the Modicon 140CRP31200 EIO head module is to manage the remote I/O devices. It can also perform other tasks. The 140CRP31200 can aid recovery to modules on the main ring experiencing communication disruption within 50 ms. It does this by utilizing RSTP, or rapid spanning tree protocol. This module is also able to configure IP parameters as well as the configurations for I/O units on the drops. It can do this for up to 31 remote I/O modules.  The Modicon 140CRP31200 head EIO module can allow a distributed I/O and control network to engage on the remote I/O network. It does this through an interlink communication path. The Modicon 140CRP31200 head EIO module also aids in Hot Standby functionality.
