Hi I have a S7-1500 1511-1PN with CM PtP Communication Module as Modbus Master. I also have an Energy meter as Modbus slave. Meter has Slave Address 10. I configurated MB_COMM_LOAD with 9600 baud, Parity 2, RESP_TO 1000. I also set interface to 8 data bits and 1 Stop Bit. Now I try to read communication status with MB_MASTER. I entered the slave adress 10, Mode 0, Data_Addr 43911, Data_Len 2. When I send the Request. FB is busy, TX-LED on Communication Modul is blinking only ,RX LED is not blinking. After every request the status of Modbus Master block keeps on switching between 7000 to 7002. My question is now what I can do or what I have forgot, not getting a communication. I am not receiving any Data from Slave. I checked on Modscan there its giving value. But not in PLC.Pls So, has anybody an idea?? Pls help regards AttachmentMODBUS_RTU_1_20171026_1646.zip (219 Downloads) |
