Defines whether the establishment of service shall be retried, the
time between retries is controlled by register S7.
Timeout is used in Dial and Transparent IO. The timeout is designed
as an inactivity timer and will be retriggered for each Data / IO
transfer. The timeout is the only normal way to terminate Dial and
Transparent IO, see Table 5 for reference of state after termination
by timeout.
Setting a timeout for any other service than transparent IO will not
cause any failure but will not have any function.

perform/establish current service.
