B. Refer to page 44 for the error code.
(2) To check input signals
.......... Function setting [IA] - [IL], [I1] - [I5], [IP] - [IR], [ECA], [ECB], [UP], [DN], [DR], [VC], [V2]
(1)
Call out the input signal in program mode [E] to be checked. (In this example, call out [IA].)
(This can be called with mode call or direct number call. Refer to pages 14 to 16. (Direct call number = "0706"))
(2)
* Turn the input for the input terminal to be viewed ON and OFF, and confirm
