What if my ControlLogix doesn't have a serial port? Or if this sample code doesn't support enough data for my app? But if you need your ControlLogix to communicate Modbus RTU, it might be worth your time to check out this free sample code to see if it'll meet your needs. Having used this code myself, I can say it's not for the faint at heart. That sample code is included by default when you install RSLogix 5000, but it's also available from. However, the folks at Rockwell Automation have been providing sample code to use the processor's DB9 serial port as either a Modbus RTU Master or Slave since version 13 of RSLogix 5000. As a follow-up to that post, in today’s article we’ll take a look at which ControlLogix processors support Modbus.ĬontrolLogix models with a built-in DB9 serial port don't natively support Modbus RTU like most of the MicroLogix line does. In a recent article we took a look at which CompactLogix models support Modbus.
