I have two feature requests. I am using the SQL Bridge Module to collect data from an AB CompactLogix L35E. If these features can be implemented in the current version of the Bridge please let me know.
Heartbeat. In my application I don’t collect the data until the end of the process. It would be nice if there were a heartbeat that changes the state of a tag in the PLC at a predetermined interval anytime the Ignition Gateway service is running. That way I wouldn’t allow the machine to start unless the data collection system is up and running. For example, the OPC Data Logger by LH Controls has a feature like this.
Handshake. I know I can already write a predefined value (e.g. “1”) when data has been successfully written, but it would be nice to echo back a key value such as the serial number string of the part for which the data is being collected.
Thank you in advance,
