are you saying that I can access sqltags via OPC-UA? even if it was OPC-UA only that would be great. having the ability to expose your tag database to outside programs via opc-whatever makes sense to me. I dont think that is the case based on this recent thread though.
I am pondering some ways to work around not having this feature and they all involve alot more scripting and all involve adding more software(or even hardware) and also limit the available data.
for instance, we need voice callouts on alarms, so that I will need to use a software like win911 or UCME.
since they cant connect directly to ignition I have a few options.
1: connect directly to opc server. downside, analog alarm setpoints will have to be manually changed in win911 as opposed to in ignition. this means that anytime a an alarm limit needs to be changed, an operator would have to email me so that I can change the alarm setpoint in win911.
2: connect directly to opc server and also setup a plc/rtu to act as a data concentrator. igntion sees an alarm on a tag and then toggles a bit in plc. win 911 looks at bit in plc thru opc server and sends alarm. downside, have to depend on hardware plus scripting to handle a like 20k alarms.
3: find a database to opc server that can look at data stored in table and export that out via opc, then have win911 look at that. That probably makes the most sense but the downside is having to rely on some outside software and the scripting for so many tags.
