With Citect for Windows 5.20, TCP/IP
sockets are now used as the mode of communication between remote
computers for CtApi. When the computer you are trying to be connect
to through ctOpen is not running, then a timeout will occur.
Currently the timeout is based on the memory mode of
communication, which retries up to 20 times. However this is not
practical for sockets as they have their own timeout mechanism.
Since the default mechanism for sockets will take about 20 seconds
to timeout, this will mean that currently ctOpen will take about 7
minutes to timeout.
