Charm

Charm devices send results to a defined port on the computer running OPC Router. OPC Router monitors this port and receives the messages (measurement results (inhibitors, microtoxins, etc.)).

No connections are configured in this plug-in. The port to which the Charm device sends data is specified directly in the trigger.

In principle, a separate port must be created for each Charm device type. Recommended procedure: All Charm devices of one type send to the same port. A single connection is created for this in the OPC Router. In addition to the results, the OPC Router also transfers information about the sending Charm device to the database. The logic for processing the results is stored in the database (or another transfer destination).

However, if a separate connection is to be created for each Charm device, a separate port must also be available for each device.

Property	Description
Timeout	When a Charm device establishes a connection, it has the specified time in milliseconds to send all data to the OPC router. If the Charm device takes longer, the connection is terminated by the OPC router.
Maximum message length	Data is sent when a connection is established between the Charm device and the OPC router. If more than the permitted number of characters are transmitted, the OPC router disconnects and considers the message to be faulty.
