Watchdog Timer Preset
(PLC08)
Use the watchdog timer to signal an alarm if the plastication profile takes
longer than expected. To inhibit the timer, enter a preset of zero.
When the QDC module starts the plastication profile, it:
starts the internal timer
stops the timer, reports execution time, and resets the accumulated value
to zero when it completes profile
sets an alarm bit if the accumulated value exceeds this preset
We recorded zero on Worksheet 7-D to inhibit the timer.
The closed-loop tuning procedures in chapter 10 require these initial
values. In that chapter, we help you select the correct final values required
by your application. For additional information, refer to section 3 of the
Plastic Molding Module Reference Manual (publication 1771-6.5.88).
After you determine initial values and enter them on configuration
worksheets, you are ready to proceed.
1. Enter all worksheet values into your PLC-5 data table.
Important: Be sure that you have not altered any setpoints, and that you
have entered each and every setpoint exactly as on the worksheets.
2. Use the procedure described in chapter 4 to download command
blocks to the QDC module. For your convenience, we repeat
download information from chapter 4 (Table 7.B).
Important: Do not download companion blocks at this time.
