Summary:
Attempts to open several concurrent HControl sockets to a CE Series IO Extender result in connection refused errors to some control devices.
Troubleshooting:
The CE Series IO Extenders support a maximum of 3 open sockets concurrently. These could be any kind of incoming socket connection to the CE device. New socket connections cannot be opened until a previous socket connection is closed.
