July 3, 2026 at 12:27 pm in reply to: ModArcPostgreSql always connects to port 5432 instead of configured PostgreSQL p #18111
MikhailModeratorHello,
Should I create a dedicated connection here (for example using server 192.168.1.4:15432) and disable “Use default connection”?
Or should ModArcPostgreSql always use the default connection defined in ScadaInstanceConfig.xml?
Both are possible.
Deployment profile stores the connection options for itself only. Try changing the connection string in ScadaInstanceConfig.xmlJuly 2, 2026 at 7:23 am in reply to: ModArcPostgreSql always connects to port 5432 instead of configured PostgreSQL p #18107
MikhailModeratorHello,
Does ModArcPostgreSql in version 6.2.2.1 always use the default PostgreSQL port (5432)?
You can change the port in ScadaInstanceConfig.xml
Try set
Server to 192.168.1.4:15432
or specify the ConnectionString parameter.Is there another configuration location for the archive modules where the PostgreSQL port must be configured?
It is possible to add connections in the archive options. I would suggest using ScadaInstanceConfig.xml
MikhailModeratorDone.
MikhailModeratorI’ll check it.
Thanks.
MikhailModeratorFixed.

This one similar.What does line #2 do?
It should be optimized.
MikhailModeratorThank you for the update.
MikhailModeratorNow it is clear. It’s looks like CRC displaying should be fixed.
Thanks.
MikhailModerator0xBADD is displayed by the parser in the same order as transferred.

MikhailModeratorIn the above config the EnableFileCommands parameter is true.
So you should see commands in ScadaComm.log
MikhailModeratorMake sure that file commands are enabled in the Communicator options.
MikhailModeratorHi,
If you mean commands sent from the Administrator application, you should find them in ScadaComm.log
MikhailModeratorRapid SCADA 6.4.7 has been released.
– Communicator API has been updated. Backward compatibility is maintained. Existing drivers do not need to be rebuilt.
– New RS Client Driver for interacting with another Rapid SCADA instance. Useful for publishing calculated channels via an OPC UA server.
– New Redundancy Selector Driver included in the Enterprise edition. This driver selects tag values from one of two devices.
– Fixed bugs in new mimic diagrams.
MikhailModeratorHi,
If you find a bug, please provide the structured info:
– Testing example
– Expected result of the Modbus parser
– Actual result provided by the Modbus parser
MikhailModeratorHi,
Then check ScadaComm.log if a command registered there or not. -
