A-23
A LAUER driver
The implementation has been successfully completed if the K8000H fault
(time-out - no PCS connected) appears in DW3 (default assignment)
and the flags P4 (restart) and P3 (general error message) are both set to
logical 1. In addition, the PCS 830.3/1 must indicate the „STATUS“ value
„7“ for all accessed channels.
An example (OB1) is contained on the floppy disk which indicates a fault
on output A0.0..0.2, expects a reset pushbutton on E0.0..E0.2, uses the
flag M20.0..M20.3 and addresses the PCS 830.3/1 board as EZ/AZ 4-15
(channel 1: 4-7, channel 2: 8-11, channel 3: 12-15). The baud rate is set
to correspond to the settings of the 8-segment DIL.
A2.6 Program integration
The following transfer operations must be performed for the integration
into your program (not required functions can be left out):
• Before calling the -PCSKOMM handling block all values read by the
PCS must be copied into the corresponding DWs. This affects:
All words read by the PCS (refer to the PCS operating console
manual)
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 the -PCSKOMM handling block all values changed by
the PCS must be written back to flags. This affects:
All words written to by the PCS (refer to the PCS operating console
manual)
Dut only if the cross-reference data block has not been adjusted.
