Ingersoll Rand to Micrologix 1500 via modbus RTU


Thread Starter


I'm trying to connect an Ingersoll Rand (IR) Intellisys to an AB ML1500 using the Modbus RTU Master driver. The Intellisys connects through an IRI converter supplied by IR. It is RS485 with Modbus RTU set to 8bit no parity and 2 stop bits. I am using a AIC+ to convert from RS232 to RS485. All the documentation I have found states that what I have done is correct. Has anyone set up these IRIs before? Is there anything in the Intellisys that needs setup?
Other than activate the remote conection in the intellisys, you are Ok, Did you set it up? is it working now?
