4. In the Protocol box, select the communications protocol for the TCP port. The
meter can provide MODBUS/TCP connections on TCP port 502 and DNP3/TCP
connections on port 20000. The host port is set automatically as you select the
protocol. Select MODBUS RTU for MODBUS/TCP or DNP3 for DNP3/TCP.
5. In the Wait for Answer box, adjust the time that PAS waits for a connection
before announcing an error and the number of retries PAS uses to receive a
response from the device if communications fail.
