4.5.4 InputRegisters(SharedwiththeModbusserver/slavefunction)
Common Items
• The client device can only read the input registers.
• Decimal place and unit are not included. Specify them on the client device.
• Due to the different number of channels between modules, unavailable channel numbers
will exist. This will not cause a register read error, so you can read the data continuously.
• The register values for unavailable channel numbers are set to 0, and the status
information is set to SKIP.
• Channel range by model
Channel type GX20/GP20 GX20-2/GP20-2 GX10/GP10
I/O channel 0001 to 6950 0001 to 6950 0001 to 6950
Math channel A001 to A100 A001 to A200 A001 to A050
• If Log scale calculation (/LG option) is performed on an AI channel, data of I/O channels
set to 32-bit signed integer or 16-bit signed integer will be an integer with two- or three-
digit mantissa.
