- PROCESS B
PV B: Choose the event whose active times must be totalised; either a digital input (DIx in
M0:MAIN or in Mx:Inputs), the event WARNING (in M0:MAIN) or the event SYSSWITCH (in
M0:MAIN).
If you want to totalise the times a process variable exceeds a given threshold value, replace A in
the equation by (A>"threshold value") and assign the process variable to PV B.
- PROCESS C
PV C: Choose the event that will reset the totalising timer, for example a digital input (DIx in
M0:MAIN or in Mx:Inputs).
- STATE: Make sure the state is set to ON.
- Press SAVE.
2. Do the settings for function F2:
- TYPE: Choose MATH
- EQUATION: Enter A>"value of the totalising timer threshold in seconds"); the value of the threshold
must have a maximum resolution of 0.1 s.
- UNIT
UNIT GROUP: Choose ON/OFF
- PROCESS A
PV A: Choose M0:MAIN and F1:MATH. If F1:MATH is not displayed in the list of process variables
for M0:MAIN, press BACK then SAVE. Go again to PV A and choose M0:MAIN and F1:MATH
- STATE: Make sure the state is set to ON.
- Press SAVE.
3. Do the settings for the digital output (DOx) (also refer to section 9.26.1):
