On the S-Bus OPC-Server, what is the new parameter “delay” on the station settings page?

FAQ #100910

Since the version 2.02.16.06 of the S-Bus OPC-Server there is the possibility to set a new parameter “delay” on the station settings page.

This parameter defines the waiting time between two connections, if the preceding connection was not finished correctly.

 

 

The main idea behind this parameter is to avoid that the S-Bus OPC-Server does call a PCD over a modem connection to fast, if the PCD does not respond to the call of the PCD or if the PCD has a bad modem connection.
If the PCD does not respond or if the connection is closed incorrectly then a new call to the PCD is only possible after that the delay time is elapsed.

The option “Use per channel” allows to define how the delay time should be used.
If for example on the OPC-Server there are three stations A, B and C which are configured and all stations does use the same modem channel (and therefore the same modem)

If the option “Use per channel” is selected and the communication to the station A does fail, then it’s not possible to make a new connection to the stations A, B and C until the delay time is elapsed.
 If the option “Use per channel” is not selected and the communication to the station A does fail, then it’s not possible to make a new connection to the station A until the delay time is elapsed.
But it’s possible to make a new connection without waiting the delay time to the stations B and C.
