5.2.3 EIP Class 3 Client/UClient [x] Connection
The PLX30 gateway supports two connected Clients and one unconnected Client
(most devices use connected Clients; be sure refer to the user manual of the
target device for verification).
The EIP Class 3 Client [x] Connections are used when the gateway is acting as a
Client/Master initiating message instructions to the server/slave devices. The
PLX30 EIP protocol supports three Connected Client Connections. Typical
applications include SCADA systems, and SLC communication.
The EIP Class 3 UClient Connection is used when the gateway is acting as a
Client/Master initiating message Instructions to the server/slave devices. The
PLX30 EIP protocol supports one Unconnected Client Connection. Unconnected
messaging is a type of Ethernet/IP explicit messaging that uses TCP/IP
implementation. Certain devices, such as the AB Power Monitor 3000 series B,
support unconnected messaging. Check your device documentation for further
information about its Ethernet/IP implementation.
Class 3 Client/UClient [x]
This section specifies the configuration for the EIP Client (Master) device
simulated on the network port.
Parameter
Value
Description
Minimum
Command
Delay
0
to
65535
milliseconds
This parameter specifies the number of milliseconds to wait
between the initial issuances of a command. This parameter can
be used to delay all commands sent to servers to avoid
"flooding" commands on the network. This parameter does not
affect retries of a command as they will be issued when failure is
recognized.
Response
Timeout
0
to
65535
milliseconds
This parameter specifies the amount of time in milliseconds that
a Client will wait before re-transmitting a command if no
response is received from the addressed server. The value to
use depends on the type of communication network used, and
the expected response time of the slowest device connected to
the network.
Retry Count
0
to
10
This parameter specifies the number of times a command will be
retried if it fails.
