Duplex Mode
Sets the duplex mode to half or full. Full would be for 4-wire installations otherwise half is
required.
Operation mode
This parameter sets the operation mode to master or slave.
Idle Gap
When receiving an modbus response from a station when this idle gap (pause with no
reception of characters) is detected the message (currently received from the station) is at
that staged forwarded on as the complete response.
Fix slave address
The address of the slave is fixed at this value. An address conversion will take place if a
message that does not contain this address is received from the TCP master. If not used
the TCP master must use the correct slave address.
Adjust slave address
The address of the slave is adjusted by this value. If left to zero then the slave address is
not adjusted at all.
