Programming
Classic:
Programming examples
for the PCD2.W6x0 can be found in a separate
manual and on the TCS Support site (
+ getting started).
xx7: the firmware writes the values according to the configuration (I/O Builder)
Watchdog: This module cannot be used on the base address 240 (or 496 for the
PCD2.M17x), because it would interact with the watchdog, and would cause a
malfunction.
For details, please refer to the
section A4 “Hardware Watchdog”
, which describes
the correct use of the watchdog in conjunction with PCD components.
