6.2 Remote Input/Output
Remote input (RX) and output (RY) are ON/OFF data. Remote data corresponds to bit data, and
16-bit data is collectively (word) processed during FROM/TO instruction execution.
“n” in the table is the address assigned to the master station by the station No. setting.
It can be calculated by the following equation:
n = (Station No. − 1) × 2
As the calculation result is expressed in decimal digits it is converted to hexadecimal digits
before substituted for “n” in the table.
Example: If the station No. of the H-LNK-A module is “1” or “5”
For station No. 1: Remote input RXn0 to RX(n+7)F → RX00 to RX7F
Remote output RYn0 to RY(n+7)F → RY00 to RY7F
For station No. 5: Remote input RXn0 to RX(n+7)F → RX80 to RXFF
Remote output RYn0 to RY(n+7)F → RY80 to RYFF
