Hello everyone
I'm looking for a solution to this:
I've 10 on/off lamps control with SSR in order to regulate infrared lamps on a blow molding machine, the values use to control timers are in N files, 0 to 7, from HMI I can send values using values inputs, it works ok, I can change individually those values and heat is controlled well.
Now I'm looking for change all the 8 N files using increments or decrements from a N value, I mean, when introduce a value in this N file, as say 1 or 2, or -1 or -2, I want to convert it value in percentage, so when I key in this value and enter, all 10 lamps values will increase or decrease in the same percent/time, if lamp one has 70 in value and lamp two has 30 in value those values will increase at the same time and remains in 70+% and 30+%, understood?
Don't know if is possible make calculations on the HMI memory or in the PLC memory.
PLC is AB Micrologix 1200A and HMI is Wecon model.
Thanks for help.
