The following transfer operations must be performed for the integration
into your program (not required functions can be left out):
• Before calling -PCSKOMM PB: all values read by the PCS must be
copied into the corresponding DWs. This affects DW12 to DW22 and
all variables but only if you do not directly access the corresponding
words by altering the cross-reference data block (example: flag words,
data buffers, input words etc.).
• After calling -PCSKOMM PB: all values changed by the PCS must
be written back to flags. This affects DW4 to DW14, all message bits
with delete behavior 2, and all set values, however only if the cross-
reference data block has not been adjusted.
The PCS assumes the following conditions after restart:
• Date and time have become invalid and thus will be immediately
transfer-red.
• All message bits are turned off. If several messages should be
activated at the restart they are newly entered in the sequence of
their numbers (lowest first) into memory.
• Text number zero is selected as idle text.
• All menus have been terminated before switching off.
• All pushbuttons and DIL-switches are transferred once after restart.
