Description

3100-MCM parameters
External dimension: 96mm × 48mm × 112mm (length × wide × Deep)
Installation method: minimum installation depth embedded: 100 mm
Opening size: 92mm × 44mm
Weight: approximately 400g

The 3100-MCM allows Rockwell Automation® CompactLogix® processors to interface easily with other Modbus TCP/IP compatible devices. The module acts as an input/output communications module between the Modbus TCP/IP network and the CompactLogix backplane. The data transfer from the CompactLogix processor is asynchronous from the actions on the Modbus TCP/IP network. Databases are user-defined and stored in the module to hold the data required by the protocol.

· Single-slot, 1769 backplane-compatible

· The module is recognized as an Input/Output module and has access to processor memory for data transfer between processor and module.

· Ladder Logic is used for data transfer between module and processor. Sample AddOn Instruction file included.

· Configuration data obtained from and stored in the processor.

· Supports CompactLogix processors with 1769 I/O bus capability and at least 500 mA of 5 Vdc backplane current available.

Modbus is a widely-used protocol originally developed by Modicon in 1978. Since that time, the protocol has been adopted as a standard throughout the automation industry. The original Modbus specification uses a serial connection to communicate commands and data between client and server devices on a network. Later enhancements to the protocol allow communication over Ethernet networks using TCP/IP as a “wrapper” for the Modbus protocol.

This protocol is known as Modbus TCP/IP. Modbus TCP/IP is a client/server protocol. The client establishes a connection to the remote server. When the connection is established, the client sends the Modbus TCP/IP commands to the server. The 3100-MCM module simulates up to 30 clients, and works both as a client and a server. Aside from the benefits of Ethernet versus serial communications (including performance, distance, and flexibility) for industrial networks, the Modbus TCP/IP protocol allows for remote administration and control of devices over an Internet connection.

It is important to note that not all Internet protocols are implemented in the module; for example, HTTP and SMTP protocols are not available. Nevertheless, the efficiency, scalability, and low cost of a Modbus TCP/IP network make this an ideal solution for industrial applications. The MVI69E-MBTCP module acts as an input/output module between devices on a Modbus TCP/IP network and the Rockwell Automation backplane and processor. The module uses an internal database to pass data and commands between the processor and the client and server devices on the Modbus TCP/IP network.
