Hello, We are comissioning a system with a S7-1200 [CPU 1214-dc/dc/dc] Firmware v4.0.0 (TIA V13) , the Siemens PLC uses the block MB_SERVER to communication with a Modbus client The Modbus Server Connection Id is = 10, and the Interface Id is 0.2 (X1 Interface), the block runs in the OB1 cycle. During the comissioning I noticed some weird status errors : 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 some times. After some time the communication stops working and the block call MB_SERVER in the Siemens PLC remains with Error=True and Status= 80C5 for a while. 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 do you think they can affect the Modbus comms ? ---------------------------------------------------------------------------------------------------- Split from Modbus TCP with S7-1500 - Error Status= 80A3 after a while. |

can you help me please? i have a same problem with MB_CLIENT, i using tia portal v14, CPU 1214C V4.2 and MB_CLIENT v4.1. I made an example project between two s7-1200 (one as a server and the other as a client) and works fine, but but when I change to the device that interests me I mark the error 16 # 80C5. Previouly i check with modscan or modbus poll the device (server) add captures. AttachmentPruebas Modbus.zip (687 Downloads) |
