Chapter 4 Using PAS Software Setting up Communications
PM130 PLUS Powermeter Series_Installation Operation and Manual 71
2. In the Protocol box, select the same communications protocol as you have set in your meter.
3. In the Response Timeout box, define the maximum time that PAS should wait for the meter
response before announcing a failure.
4. In the Break Timeout box, define the maximum line idle time that PAS should wait after receiving
the last message character before closing a connection with the Modbus RTU or DNP3 protocol.
It does not affect ASCII communications. Note that this time is added to the message transfer
time, and excessive increasing it may slow down communications. If you frequently receive the
“Communication error” message, try to increase Break Timeout.
5. In the Retries box, define the number of attempts that PAS should use to receive a response
from the meter in the event the communication fails, before announcing a communication failure.
4.3.2 Communicating through the Internet
If you are communicating through the Ethernet port, define the IP address of your meter on the network.
To configure the meter IP address:
1. On the Instrument Setup tab, select Internet Site.
2. Click on the Connection tab.
3. Click on the IP address and type in the IP address of your meter. The default IP address preset
in the meter at the factory is 192.168.0.203.
4. In the Protocol box, select the communications protocol for the TCP port. The meter provides
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/TCP 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.
