Please remember that the use of the ladder logic COUNTERS do come with some limitations:
- The COUNTER resets to an special value of "-1". This happens as a result of PLC reset, PLC power up and the use of the [RSCtr] Special function.
- The maximum value that the counter can reach is determined by the Set Value in the I/O table.
- The maximum Set Value is 9999 decimal.
- The COUNTER will down count from 0 to the Set Value. There are no negative numbers other than the special "-1" value.
- The contact associated with the COUNTER has some interesting behaviors in regards to when the contact is active.
