STL counter confusion

6/19/2023 6:00 AM	Rate (0)
Mikluk Posts: 12 Rating: (0)	Hi all, could anybody explain to me what am I doing wrong? I am confused about the counter procedure. In the FB I have an array "Servo_Fault_Counter". If I am counting Servo_Fault_Counter[0] in the network 4, value is changing on the Servo_Fault_Counter[4]. Similarly for Servo_Fault_Counter[1] is changing value on the Servo_Fault_Counter[5]. If I put same lines to different network ( nw3, 5 does not matter ), counter is working correctly. Where is the problem, pls? Attachment Counter.jpg (1169 Downloads)

	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
