Bit Input Offset
0 to 9999
This parameter defines the start register for Modbus command data in the
internal database. This parameter is enabled when a value greater than 0 is set.
For example, if the Bit Input Offset value is set to 3000, data requests for Modbus
Input Register address 10001 will use the internal database register 3000, bit 0. If
the Bit Input Offset is set to 3000, data requests for Modbus Coil register address
10016 will use the internal database register 3000, bit 15. Function code 2 is
affected.
Holding Register Offset
0 to 9999
This parameter defines the start register for the Modbus Command data in the
internal database. This parameter is enabled when a value greater than 0 is set.
For example, if the Holding Register Offset value is set to 4000, data requests for
Modbus Word register 40001 will use the internal database register 4000.
Function codes affected are 3, 6, 16, & 23.
Word Input Offset
0 to 9999
This parameter defines the start register for Modbus Command data in the
internal database. This parameter is enabled when a value greater than 0 is set.
For example, if the Word Input Offset value is set to 4000, data requests for
Modbus Word register address 30001 will use the internal database register
4000. Function code 4 is affected.
