Allen-Bradley ControlLogix Ethernet Driver Help
1. For network adapters available on the system, check the network adapter list in the communications
server application (located in channel properties). If the specified adapter is not in this list, steps should
be taken to make it available to the system. This includes verifying that the network connection is enabled
and connected in the PC's network connections.
2. Determine how many channels are using the same adapter in the communications server application.
Then, reduce this number so that only one channel is referencing the adapter. If the error still occurs,
check to see if other applications are using that adapter and then shut down those applications.
Winsock initialization failed (OS error = n).

Indication Possible Solution
10091 The underlying network subsystem is not ready for
network communication.
Wait a few seconds and restart the driver.
10067 The limit on the number of tasks supported by the
Windows Sockets implementation has been reached.
Close one or more applications that may be
using Winsock and restart the driver.
Winsock V1.1 or higher must be installed to use the Allen-Bradley ControlLogix
Ethernet device driver.
Error Type:
Fatal
Possible Cause:
The version number of the Winsock DLL found on the system is less than 1.1.
Solution:
Upgrade Winsock to version 1.1 or higher.
