When the ladder logic sends a message to a server, it can request that the
socket be closed after the message is sent. The server control word in the output
image is used for this purpose. Place a value of 1 in this register to gently close
the connection after the message is sent. If a value of 2 is placed in the register,
the server will abort the connection to force the socket closed (send a message
with the Reset Flag set to the client). Most applications will have the client close
the socket.
5.3 Cable
Connections
The MVI46-GEC module has the following communication connections on the
module:
One Ethernet port (RJ45 connector)
One RS-232 Configuration/Debug port (RJ45 connector)
5.3.1 Ethernet
Connection
The MVI46-GEC module has an RJ45 port located on the front of the module
labeled "Ethernet", for use with the TCP/IP network. The module is connected to
the Ethernet network using an Ethernet cable between the module's Ethernet
port and an Ethernet switch or hub.
Note: Depending on hardware configuration, you may see more than one RJ45 port on the
module. The Ethernet port is labeled "Ethernet".
Warning: The MVI46-GEC module is NOT compatible with Power Over Ethernet (IEEE802.3af /
IEEE802.3at) networks. Do NOT connect the module to Ethernet devices, hubs, switches or
networks that supply AC or DC power over the Ethernet cable. Failure to observe this precaution
may result in damage to hardware, or injury to personnel.
Important: The module requires a static (fixed) IP address that is not shared with any other device
on the Ethernet network. Obtain a list of suitable IP addresses from your network administrator
BEFORE configuring the Ethernet port on this module.
Ethernet Port Configuration - wattcp.cfg
The wattcp.cfg file must be set up properly in order to use a TCP/IP network
connection. You can view the current network configuration using an ASCII
terminal by selecting "@" (Network Menu) and "V" (View) options when
connected to the Debug port.
