Programming
Reset
When the module or CPU powers up, both analogue outputs of the PCD3.W500
module are set at the maximum value of +10 V (or a random value between 0 and
+10 V). If this should cause problems, XOB 16 (the cold-start routine) should be
used to initialize both these outputs to zero or any desired cold-start value.
If the debugger is connected or the P100 handheld service device is plugged in, there is no
cold-start when the CPU supply switches on. Both analogue outputs of the PCD3.W500 are
then set to the maximum value of +10 V, despite the reset routine.
Programming examples for the PCD3.W500 can be found on the TCS Support site.

Watchdog: This module can interact with the watchdog, if it is used on base address 240. In
this case, the last input with address 255 cannot be used.
For details, please refer to the section A4 “Hardware Watchdog”, which describes the correct
use of the watchdog in conjunction with PCD components.
