Communication Module for CompactLogix
The inRAx Modbus TCP/IP Communication Module is designed to allow CompactLogix® /MicroLogix® processors to interface with other Modbus TCP/IP protocol-compatible devices, including not only Modicon® processors, but also a wide variety of other Client and server devices. The MVI69-MNET module is a single-slot solution that provides a powerful connection between Rockwell Automation® CompactLogix processors and Modbus TCP/IP network applications. The Modbus TCP/IP network applications include those networks hosted by Modicon Quantum processors, networks controlled by operator interface software applications, and the growing number of manufactured devices that support this protocol.The module acts as an input/output module between the Modbus TCP/IP network and the CompactLogix backplane. The data transfer from the processor is asynchronous from the actions on the Modbus TCP/IP network. A 5000 16-bit register data space in the module exchanges data between the processor and the Modbus TCP/IP network. SpecificationsModbus TCP/IP Server Protocol SpecificationsThe server driver supports connections to up to five Modbus TCP/IP Clients usingService Port 502 with standard MBAP messaging, and up to five Clients using Modbus RTU/ASCII on Service Port 2000 (and others).Modbus TCP/IP Client Protocol SpecificationsThe Client driver supports the active reading and writing of data with Modbus TCP/IPcompatible devices.This one Client supports up to 100 commands, which can be addressed to one or moreservers.Status DataCommunication error codes, success-fail counters, and port states are available, as wellas module diagnostic data.
