Hello, This was a problem that wasfixed in STEP7 BASIC SP2 Check the version of your MB_SLAVE block in the MODBUS library. It shoud be v1.1. Service Pack for STEP7 BASIC (SP2) Download and install the SP2 (you should delete the original MB_SLAVE block and get the new block from the library into your code.) Good Luck |

Unfortunately I was unable to clear the fault hbrianjr: I had installed SP2 and replaced MB_Slave, and nothing has changed Pegaia: data recorded and should be read only from / to data blocks, and I move them into variables. Maybe now I'll try to explain: I'm using Mb_slave and Mb_comm_load as it is in the manual, even used the program's Pegaia "Modbus.zip" https: / / www.automation.siemens.com/tf/WW/en/Posts/33967 = False # top and added PID_compact and received this same error "Illegal data value". Below I give the modified program's Pegaia Modbus with PID_Compact, if anyone knows how to help me thank you AttachmentModbus.zip (817 Downloads) |
