This subsection discusses the Socket Packet ID Settings area of the Ethernet Device Configuration page.
Cmd/Resp Response To
Modbus/TCP Based On
Method for returning responses to Modbus/TCP interfaces.
• If you select IP-Address (default), all responses will be returned to the IP-
Address the original command was received from. This may the same or
different TCP connection.
• If you select TCP-Connection, all responses will be returned to the same TCP
connection the original command was received from.
Note: TCP-Connection is typically required when multiple controllers are
communicating from the same PLC or computer.
Socket Packet ID Settings
Rx Timeout
Between
Packets
Specifies the following information, once the start of a packet is received:
• How long the DeviceMaster UP should wait (in milliseconds) before timing-out, if the
ETX Rx Detect length is one byte or two bytes and the ETX byte(s) are not received.
• The time to wait in milliseconds between Ethernet packets if the ETX Rx Detect
length is set to none.
