Timers
Possible addresses of the
type "Timer"
Permitted modify/force values Explanation
T 1 0 Conversion to milliseconds (ms)
T 12 20 Conversion to ms
T 14 12345 Conversion to ms
T 16 s5t#12s340ms
T 18 3 Conversion to 1s 300 ms
T 20 3s Conversion to 1s 300 ms
Modifying a timer affects only the value, not the state. This means that the timer T1 can be
modified to the value 0, without the result of logic operation for A T1 being changed.
The strings 5t, s5time can be written in either upper or lower case.
Counters
Possible addresses of the type "Counter" Permitted modify/force values
C 1 0
C 14 20
C 16 c#123
Modifying a counter only affects the value, not the state. This means that Counter C1 can be
modified to the value 0 without the result of logic operation for A C1 being changed.
