COMPARISON OPERATION
The following FBs perform comparison operation (, >, =, <, ).
To set initial values of public variables of the general process FB arranged on a user-defined tag FB in "FB
Property" of the engineering tool, refer to the following.

Comparison (>) with setting value (M+P_GT)
M+P_GT
This FB compares (>) the input 1 (IN1) with the input 2 (IN2) using a setting value and hysteresis and outputs the result to the
comparison output (B_). This function block always outputs values to the input 1 (IN1) from the output (OUT_).
