Parameter name Function
Protocol Select the application protocol to run on the RS-485 interface
Address Set the node address. Note: The address range depends on the protocol selected
in par. O-30 Protocol
Baud Rate Set the baud rate. Note: The default baud rate depends on the protocol selected
in par. O-30 Protocol
PC port parity/Stop bits Set the parity and number of stop bits. Note: The default selection depends on the
protocol selected in par. O-30 Protocol
Min. response delay Specify a minimum delay time between receiving a request and transmitting a
response. This can be used for overcoming modem turnaround delays.
Max. response delay Specify a maximum delay time between transmitting a request and receiving a
response.
Max. inter-char delay Specify a maximum delay time between two received bytes to ensure time-out if
transmission is interrupted.
