Timer
The number of available timers is 256 in the PS program and 512 in the PN pro-
gram. They are selected by assigning an address with the prefix ‘T’
(PS:T000…T0FF, PN:T000…T1FF). A timer passes a TRUE at its input to its out-
put with a time delay. Depending on the requirements of the circuitry, a selection
can be made between a self-holding and a non-self-holding timer. Both types are
available with 2 different increments (10ms and 100ms). The adjustable range is
between
0.1s…6553.5.
During
address
assignment
(PS:T000…T0FF,
PN:T000…T1FF) the timer is automatically assigned an address from the ‘N’
memory area with the same address. This register serves the timer as counting
register and permits the current counter reading to be read out.
Depending on the capacity stage of the PROTECT-PSC there are different toler-
ance ranges for the timer.

Please observe these tolerances when creating programs and use the TMRH tim-
ers to produce more exact time delays.
