Hi Folks,
I have a C-More 6" panel (my first panel! yeah!) on the way and I want to try it out on this AB Micro820 PLC. I am using Connected Components Workbench to program the 820. I will have to use Modbus Mapping to accomplish this if I understand correctly. Since time variables cannot be mapped this way for either read or write, I suppose I will have to convert these variables to a REAL or INT value.
Is it possible to change the timer increments? It seems all the timers are based on milliseconds. Integer or Real conversion for a 90s timer is 90000.
This timer is a retentive timer used to measure total rotations. One of the outputs at the panel will read percent of rotation and a writable input will be Rotation time.
Dividing the Preset Time by the Elapsed Time on the retentive timer in order to get percent of rotation gives me ridiculous numbers. e.g. 90000 divided by 13334.. way too many decimal places!
Or am I showing my ignorance by going about this in the wrong way?
Any ideas are appreciated,
