The G9SP-series Controllers support the following logic functions and func-
tion blocks.
Icon
Outputs the logical complement of the input
condition.
Outputs the logical AND of the input conditions. All unit versions
Outputs the logical OR of the input conditions.
Outputs the logical NAND of the input condi-
tions.
Outputs the logical NOR of the input conditions. Not supported.
Outputs the exclusive OR of the input condi-
tions.
Outputs the exclusive NOR of the input condi-
tions.
When the input signal turns ON, RS-FF holds
the ON status in the function block and continu-
ously connects to the output.
Compares the input signals to the set value
and turns ON the output if they match.
Compares the input signals to the set value
and outputs the comparison result.
