7.4 System Variables for Interface Input/Output Signals
(1) System Variables for Interface Input Signals
By entering a system variable for interface signals at the right part of an operation
expression, the ON/OFF state of 32-point input signals special for macro programs are
read. The relationship between the input signals and the system variables is indicated in
Table 7.3.
Interface Input Signals and System Variables Table
• The values read by the system variables indicated in Table 7.3 are either “1.0” or “0.0”
depending on whether the corresponding input signal is ON or OFF.
