Inputs : 512 – ( 512 + Changed number of input (Bits)
Outputs : 512 – ( 512 + Changed number of output (Bits) )
In this example, Input byte is 20 bytes (160 bits) and 512-671 is displayed in Inputs.
Also, Output byte is 20 bytes (160 bits) and 512-671 is displayed in Outputs.
n = (Station − 1) × 2
When CC-Link board station is 1
Remote Input RXn0 to RX(n+5)F → RX00 to RX5F
Remote Output RYn0 to RY(n+5)F → RY00 to RY5F
When CC-Link board station is 4
Remote Input RXn0 to RX(n+5)F → RX60 to RXAF
Remote Output RYn0 to RY(n+5)F → RY60 to RYAF
