• Select the FSTART instruction and enter the function name, FUNC-01.
The function box will be displayed.
Next, create the function input section, address input section, and output section as
described below.
2. Entering the Inputs
The following example is for inputting bits (defined using B-VAL).
a) Enter the N.O. CONTACT instruction and the bit register number MB000001.
b) Input the FIN instruction. The function input parameters and the N.O. CONTACT
instruction will be connected.
Create the input section for integer data (defined using I-VAL), double-length integer
