MB-700 –Modbus RTU TCP/IP Processor Module
Part Number
MB-700 (Modbus RTU/TCP Processor Module)
Description
The MB-700 is a multi-function module integrated into the SYSTEM302 that has two types of
functions: bypass (gateway MODBUS TCP/IP e MODBUS RTU) and Modbus data concentrator.
The MB-700 allows the remote configuration of devices that use the MODBUS RTU protocol. So,
when the device receives a Modbus TCP/IP message and does not have its address, it will pass the
communication frame to a lower level of the Modbus RTU network. At the same time the MB-700
collects data from lower levels of this network communicating with the CPU through the Ethernet
network. It uses a PS-AC-R Power Source Module. Please refer to the MB-700 manual for further
details.
