PLC FUNCTION
1.10 Analog I/O function
1.10.1 Analog input
Analog input value of termianl 1, 2, 4 can be read from D9245 to D9247.
Actual read processing is performed at the END processing of the sequence.
1.10.2 Analog output
Analog output from each terminal can be performed by setting value on D9251 to
D9254.
Output from PLC function can be performed by setting "7" in output signal selection
parameters of each terminal (terminal FM: Pr. 54, terminal AM: Pr. 158, terminal AMO,
AM1: Pr. 306, Pr. 310).
Actual read processing is performed at the END processing of the sequence.
