Mitsubishi Melsec-A (TCP/IP) ID:22


Interface Description

IGSS32 offers a TCP/IP interface for the Mitsubishi Melsec A/AnS type PLC equipment. A standard Ethernet interface board in the PC together with standard Windows TCP/IP protocol stacks enables IGSS32 to communicate with Mitsubishi Melsec A/AnS CPUs equipped with AJ71E71-S3, AJS71E71-Bx-S3 or compatible Ethernet interface modules.

The IGSS32 system polls the PLC equipment cyclically according to one of four user-defined time intervals. The time intervals are configurable from 100 milliseconds to 999 seconds. The system automatically groups process data in data blocks - thus fully exploiting the the communication link in relation to the present configuration.

NOTE: The IGSS32 TCP/IP ethernet interface driver is compatible with the serial driver for Mitsubishi Melsec-A/AnS PLCs. This means that no changes has to be made in the IGSS32 system when switching between these drivers.
