Hi to all, i wrote a slave instruction on S7-222, the programm downloaded to PLC without any problem. when im try to use modscan as master the messages i get are "MODBUS message TIME-OUT" and "Recieved Invalid Response to MODBUS Query", when im checking the BIT and byte for Done and error the results are: for Done=1 for Init block=5(5 Holding registers overlap Modbus Slave symbols) and for slave block=10(10 Slave function not enabled). i can see that modscan send request but PLC wont respose. what does it mean every one of this errors? i attach the program i wrote if someone could check it and instruct me what to do, or to correct the problem. I'll keep trying to make it work!. Thank in advance for help. I very appreciate your help. Best Regards, Greg. Attachmentmahteshim_Dryer_left_TEST.zip (102 Downloads) |
