Timers - HEIDENHAIN TNC 426 PB/M Technical Manual

7.2.3 Timers

7 – 16
The PLC has over 256 timers, which you control through special markers with
the symbol T. You must define the cycle time of timers T0 to T47 in machine
parameter MP4110.x. One time unit (input value 1 in MP4110.x) corresponds
to the PLC cycle time.
You can start the first 48 timers by setting one of the timers T0 to T47 for at
most one PLC scan (otherwise the TNC restarts the timer with the negative
edge for each additional scan). The TNC reserves the timer with the duration
defined in MP4110.x, and sets the markers T48 to T95 (timer is running) until
the defined duration has expired.
You can also set and start the timers T0 to T47 with Module 9006. Timers T96
to T303 can be started only through Module 9006.
