Good day excellence, I'm trying to achieve the communication between S7-1200 PLC V4 / CM1241(RS485) and the Delta Temparature control , but so far there is NO success . The Error that i'm getting is 8383 which really confuse me because I've checked my DATA PTR and it's looks okay , i'm reading 0..5 words and the DATA LEN is 12 bytes which i think is fine . May i ask you guys to assist me please. Thanks

Hello, Address 4096 is a coil address. One coil is one bit. When you use DATA_LEN=12, you try to read 12 bit. Regards, |
