Step 4:
Via a comparator the running time of the second timer no. 1 is supervised. Enter the limit of 900 seconds. The
comparator must be active above the limit.
Step 5:
In the „I/O configuration“ the actions are assigned as follows.
Channel No. 1
Source
Permanently active (Flag 2)
Target or action
Run Sec-Timer
No. 1
Channel No. 2
Source
Comparator
No. 1
Target or action
Reset Sec-Timer
No. 1
Channel No. 3
Source
Permanently active (Flag 2)
Target or action
Run Integrator
No. 1
Channel No. 4
Source
Comparator
No. 1
Target or action
Save parameter
3449
Channel No. 5
Source
Comparator
No. 1
Target or action
Reset Integrator
No. 1
Note:
The channels are worked out subsequently by UMG507 beginning with channel no. 1. Therefore it is neccessary to
save parameter 3449 before the reset of the integrator. If saving would be carried out on channel no. 5 and the reset on
channel no. 4, no temperature value was saved.
