This Modbus/Serial Integration Kit for ioControl allows Opto 22 Ultimate I/O controllers, using ioControl, to connect via a serial network to any Modbus device and communicate using the Modbus RTU or ASCII protocols. The Integration Kit contains a set of ioControl master subroutines, an example Modbus slave strategy, and ioDisplay master and slave projects to show communication between the example strategies and a Modbus device.
Before including the subroutines in your strategy, you will need:
- a PC running ioControl software and the Modbus/Serial Integration Kit for ioProject
- an Opto 22 controller with a firmware revision of R7.0c or later
- ioProject Basic 7.0 or later
The Modbus/Serial Integration Kit for ioProject (Part # IOP-INT-MBSER) allows Opto 22 controllers, using ioControl, to connect via RS-232 or RS-485 to a Modbus device and communicate using the Modbus RTU or ASCII protocol. This guide describes the kit and how to use it.
