Module 9197 Start cyclic timer
Module 9197 can define and start a timer > T96 as cyclic timer. After 
expiration of the defined time, the timer is reset for a PLC cycle and afterwards 
is automatically restarted.
 A cyclic timer can be stopped by setting the run time to 0.
 The programmed timer is set immediately after the module call.
 The run time is programmed in [ms].
 The control rounds the actual run time up to integral PLC cycle times.
Call:

96 to 999
PS B/W/D/K <Run time>
