HC900 communicaton InTouch SCADA

[_V_]

Hello everyone.

I am using HC900 plc from honeywell and the software HMI scada.
I can comunicate with the plc using scada, it appears the green light and when I take out the cable I lose connection, but I cant read nothing from it, only zeros.
Do you guys know why ?

In the MBTCP driver:

Change Maximum Outstanding Messages to 1.

Try different combinations of 0-Based Addressing, use Concept Data Structures, and reset or reactivate after saving each change.

Do you know the Modbus Unit ID/Slave ID? If it is 1, (or you are not sure), try using the Modbus Bridge and ModbusPLCRS object so you can set it to 1. If you are using the ModbusPLC object, it assumes Unit ID 255 which may not be correct.
