Hello, We are comissioning a system with a S7-1500 [CPU 1516-3 PN/DP] Firmware 1.6 (TIA V13 upd 6) , the Siemens PLC uses the block MB_SERVER to communication with a Modbus Master (a ControlLogix using the Prosoft Modbus Module MVI56E-MNETR). The Modbus Server ConnectionId is = 1, and the Interface Id is 64 (X1 Interface), the block runs in the OB1 cycle. During the comissioning I noticed some weird status errors : 16#80C4, 16#80C5 . I didn't know exacly the errors meaning, but I assume that they are internal status (like connect, disconnect, timeout, etc...) , but the communication works fine. After some time the communication stops working and the block call MB_SERVER in the Siemens PLC remains with Error=True and Status= 80A3. Could you please help us ? Do you have some idea what can be wrong ? I have also a Profinet IO Controller, a HMI in the X1 Interface, and the Simatic NET communication in the X2 Interface (corporate network), do you think they can affect the Modbus comms ?

So...in summary...I would suggest you to change the Connection ID to another, unused value! |
