I need help in writing the logic (I need be able to recipe setting). The machine process has 4 stages: Stage 1 = Xhour = XSpeed = XTemperature Stage 2 = Yhour = YSpeed = YTemperature Stage 3 = Zhour = ZSpeed = ZTemperature Stage 4 = Ahour = ASpeed = ATemperature Each of the value, X, Y, Z & A will have it's default value in the program (the default value to set during programming - theis default value can be changed via sms all of the X, Y, Z & A values need be changed via sms (When user changes or modifies Xhour or Yhour or Zhour or Ahour - NO DATA VALIDATION REQUIRED. However, Xhour + Yhour + Zhour + Ahour = MUST NOT EXCEED 48 hours OR when HUMIDITY % = USER PRE-SET. When user modifies the X, Y, Z & A values of the speed & temperature need be checked by the program so that new values set via sms does not exceed the minimum & maximum value defined in the program. I was looking for similar logic over here in the forum. Please do help to point to the relevant examples if any (already available within this forum). Thank you.

The values of each timer are transferred to the VM memory via Parameter VM Mapping and then read in again via an analog network inputs. Please note: The time format of the timers is h: m. Therefore, the values in the timebase are minutes. 12 hours = 720 minutes, 48 hours = 2880 minutes. Attachment Compare_sum_of_all_timers_0BA8.Standard.zip (281 Downloads)
