The method for specifying "n1" for an A2C is different from that for an A52G as mentioned below.
1) A2C: Head station number of remote terminal modules is specified at "n1".
2) A52G: specify "n1" with (head number of remote terminal module) + (100).
(Example)
When the head number of remote terminal module is 9, specify K109 (9+100).
(2) The bit device specified at (D1) is used as a communication complete flag.
This device turns ON after execution of the END instruction of the scan during
which communication processing with a specified remote terminal module is
completed, and turns OFF after execution of the END instruction of the next
scan.
(3) Though the data specified at (D2) is dummy data which calls for no processing
in the program, specify any output (Y) number at this.
