Free software tools help connect Ethernet-based PACs to Modbus/TCP, Modbus Serial, or Allen-Bradley DF1 devices. They allow connection and communication
with Modbus devices from other vendors. The DF1 integration kit enables the same type of integration with the Allen-Bradley PLC5, SLC500s, and other hardware using the DF1 protocol. The Modbus/Serial integration kit for ioProject lets Opto 22 controllers running ioControl (ioProject's control programming component) create an RS-232 or RS-485 serial connection with any Modbus device and communicate with it using the Modbus RTU or ASCII protocol.
