ModCom Pro is a Windows based program used to simulate a Modbus device (up to 16 devices at once). ModCom Pro is able to act both as a master and a slave.
In the slave mode you can open up to 16 MDI documents at once, each one simulating a Modbus enabled device. In the Master mode ModCom Pro acts as a host system requesting data from any Modbus enabled device from PLC`s to PC`s to dedicated embedded controllers.
ModCom Pro can communicate with virtually any device that supports the Modbus RTU or ASCII protocol. Both RS-232 and RS-485 serial links are supported with special attention given to RS-485.
