Hi, Dears,
I have one modbus device which connect to Igniton by modbus RTU over TCP, now connection is ok, but when I want to read the HR area, this device requires a special request, actually I don’t know exactly which kind of request will be sent from Ignition side automatically.
for my device, the address are in x16, so for example, if I want get data from address A20H-A30H, 1st I need send request 00 03 A0 20 00 11 A7 DD (x16 also) then I will get the result from the device, by the way is a singal chip machine, and Ignition version is 8.0.13, so is it possible to edit read HR request and send it to the device?
thanks a lot!
