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.
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
