	Regards, Jacek What is confusing you is the fact that you never see a number but always its digit representation. So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine

Please tell us how to read the variables. The controller activates the PN / IO interface X150 P1 and P2 (IP 192.168.1.122) The PN / IE interface is not activated (IP 169.254.11.22)

sad1002 Posts: 17 Rating: (0)	I did as you said, as I understood in the file OPC_Data.ati there are variables and their addresses in the controller memory. But I can not decipher there most likely ASCII to HEX or something like that. Could you, by the example of one variable, show how to decode its address in memory? For example, "Stat_cycle_counter".
