YASNAC PCNC I/O Signal Function Manual Chapter 7: Programming Support Functions
• By entering system variable #1032 in the right part of the operation expression, it is possible
to read the ONN/OFF state of the 32 points of the input signals (UI0 to UI31) collectively in a
positive decimal value.
• It is not possible to substitute a numeric value by entering system variables #1000 to #1030 in
the left part of the operation expression.
(2) System Variables for Interface Output Signals
By entering a system variable for interface signals at the left part of an operation expres-
sion, the ON/OFF state of 32-point input signals special for macro programs are set. The
relationship between the output signals and the system variables is indicated in follow-
ing table.
Interface Output Signals and System Variables Table
• By setting either “1.0” or “0.0” to the system variables indicated in the following table , the
coorresponding output signals are output either in “ON” or “OFF” according to the set value.
Variable Value Table
If a value other than “1.0” or “0.0” is set for #1100 to #1131, it is treated as indicated below:
