5.11.7 Status LEDs of Function Keys
For each function key status LED, a 2-bit piece of information is avail-
able in the cyclical polling area. One bit activates or deactivates the
corresponding status LED, the other bit displays the flashing attribute
of the status LED. The status LEDs can only be influenced by the con-
troller.
The following exceptions apply:
• You have programmed a function key as a direct selector key for a
message mask
• You have entered a value greater than 0 (zero) as the message pri-
ority.
In these cases, the status LED of this function key cannot be influ-
enced by the controller! In these situations, the status LED can only be
controlled using the message functions.
If the operating device you are using has less status LEDs than can be
controlled here, the superfluous bits have no function.
To minimize the transfer times, select the length of the polling area so
that only the bytes required for status LEDs are transferred.
5.12 Running Time Meter
Each operating device has 8 running time meters.
Control Byte Each running time meter is assigned a bit in the control byte. Using the
control byte, the controller can influence the running time meters in the
operating device.
If bit X is set in the control byte when polling is carried out, the running
time meter X is incremented. In each case, the value of the running
time meter is stored in the system variable CounterX.
