Modbus is a communication protocol developed by Modicon in 1979 for linking devices with Modicon PLCs using a master/slave relationship. Different versions of Modbus today include Modbus RTU, Modbus ASCII and Modbus TCP. Where Modbus RTU and ASCII are based on serial communication like RS-232 and RS-485, and Modbus TCP is based on Ethernet communication. It's a standard, truly open and widely used in industrial automation field.

The iP-8000-MTCP series is an I/O unit with Modbus protocol. It supports most of high profile I-8K and I-87K series I/O modules. SCADA and HMI software can easily access variant I/O signals via the iP-8000-MTCP.

Auto Configuration
The configurations of I/O modules are backed up in the EEPROM of the iP-8000-MTCP. The iP-8000-MTCP automatically checks and restores the configurations to each I/O modules during booting procedure. If one I/O module fails, the operator just needs to replace it with another one. And then check the LED indicators to know whether the auto configuration is performed correctly.

Firmware Programmable
The iP-8000-MTCP is not just an I/O unit but also a programmable controller. Programmers can use the Modbus SDK to customize the firmware in C language.
