glavanov Posted March 23, 2022 Report Posted March 23, 2022 (edited) Hello people, i have a task in which i have to read values from S7-300 Data Block via GOT SImple HMI (S7-300 Ethernet OP driver). I don't have much experience with S7 data blocks and i need someone to confirm if my addressed in the HMI are entered correctly while waiting for the hardware. In other words i need to know if the DB address offsets are coresponding to Word numbers in the HMI. I need to know if i'm undertandig right the Address offset after the array structure... Thank you in advance. S7-GOT.GTX S7-GOT.GTX Edited March 24, 2022 by glavanov
Thiago Turcato Posted March 27, 2022 Report Posted March 27, 2022 As further as I know, DB inside data cannot be accessed by GOT Simple but I will check further with my colleagues to see if anyone found a way to do it easier than transfer data to/from %M type devices in S7-300 PLC and let you know! Best Regards!
