User-programmed socket statistics for L20E, L20E, and L70E controllers
The user-programmed socket protocol monitors socket statistics for L20E, L50E, and L70E controllers. In
FactoryTalk Design Workbench
, use socket instructions in controller programs to create and open sockets for communications using Transmission Control Protocol (TCP) and User Datagram Protocol (UDP).Socket instruction blocks include:
The parameters in the following table are available when you select
User-programmed sockets
from the Protocols
list.Parameter | Description |
|---|---|
Total available | Displays the maximum number of supported socket instances. |
Created | Displays the number of created socket instances.
For more information, see the SOCKET_CREATE instruction. |
TCP connections | Displays the number of TCP instances. |
Clients | Displays the number of socket instances opened as TCP clients. |
Servers | Displays the number of socket instances opened as TCP servers. |
Non-configured | Displays the number of socket instances that are not configured yet. |
UDP datagrams | Displays the number of socket instances opened as UDP. |
Packets | |
TCP success - Read | Displays the number of read TCP packets. |
TCP success - Write | Displays the number of written TCP packets. |
TCP failure - Read | Displays the number of unread TCP packets.
For more information, see the SOCKET_READ instruction block. |
TCP failure - Write | Displays the number of unwritten TCP packets.
For more information, see the SOCKET_WRITE instruction block. |
UDP success - Read | Displays the number of read UDP packets. |
UDP success - Write | Displays the number of written UDP packets. |
UDP failure - Read | Displays the number of unread UDP packets.
For more information, see the SOCKET_READ instruction block. |
UDP failure - Write | Displays the number of unsent UDP packets.
