Good day fellow engineers,
I am new to Citect and the world of automation. Been tasked to work with Advantech ADAM 4024 I/O modules. It has 4 digital Inputs and 4 analog outputs. I am able to poll from CitectSCADA for the 4 analog outputs with no issue, but the polling of the 4 digital inputs always returns a #BAD comment.
I did abit of digging with putty application, to sniff for the MODBUS request and response package. It seems that Citect is requesting for a 2bytes responses. Because the ADAM 4024 only have 4 digital input that corresponds to a 8bits, the response with an exception code #1.
I also tried using MODScan to request for the 4digital inputs of ADAM 4024. I was successful in doing so as I can dictate the number of registers to read, in the ADAM 4024 cases is 4.
Has anyone ever encountered or overcome this similar issue with ADAM I/O module? Any sharing of your experience will with be valued. Thank you very much.
Cheers.
