SIMATIC S7 Connector supports the Update Request functionality. This enables you to receive the complete process image of the configured tags. In case the application fails to receive the initial publish of the complete process image by the SIMATIC S7 Connector app, you can initiate request for the same.
You must add a topic in Databus in the following format to receive the configured data: ie/c/j/simatic/v1/updaterequest
where ie
: industrial edge, c
: control, j:
json
The JSON payload structure for Update Request is as follows:
{
"Path" : "<connector-id>/<connection-name>/<collection-name>"
}
connector-id
should be s7c1
and collection-name
should be default
for S7 Connector, since only the default
collection is currently supported.
