A question about Siemens PLC programming
Thread Content
A problem in programming Siemens PLCs (S7-200 series): how to most easily determine whether all the data in those dozens of consecutive bit addresses from V0.6 to V10.4 are 1.
What I mean is, for example, in terms of the alarm control for the production process: when the temperature at monitoring point #1 is normal, V0.6 takes a value of 1; when the temperature at monitoring point #2 is normal, V0.7 takes a value of 1; when the temperature at monitoring point #3 is normal, V1.0 takes a value of 1, and so on. When the temperature at monitoring point #79 is normal, V10.4 takes a value of 1. When all the monitoring points are normal, that is, when all 79 consecutive bit addresses from V0.6 to V10.4 have a value of 1, Q0.5 is set to 1, thereby turning on the indicator light on the cabinet. When programming in ladder logic, it’s too troublesome to use 79 contacts in parallel. Is there any quick way?
