Hi,
Siemens product sheets for their CPUs state that the number of IEC timers are "unlimited".
But I thought that the number of IEC timers would be limited by the max number of DBs for the particular CPU, as each IEC timer must have a DB associated with it.
So, which is correct:
1. The number of IEC timers on an S7 CPU is unlimited.
2. The number of IEC timers on an S7 CPU is limited by the number of available DBs.
Thanx
