I have PLC tags received from an OPC interface which represent the future setpoint values and the effective Timestamp. I want to show a trend with those future values. Example :
Setpoint-Phase1-Value tag : 10
Setpoint-Phase2-Value tag : 20
Setpoint-Phase3-Value tag : 30
Setpoint-Phase1-TS tag: 01-may-2019 09:00
Setpoint-Phase2-TS tag: 01-may-2019 09:15
Setpoint-Phase3-TS tag: 01-may-2019 09:45
I want to put thoses values in a Future tag:
Setpoint-Future-Value tag :
01-may-2019 09:00 10
01-may-2019 09:15 20
01-may-2019 09:45 30
I tried creating 3 AF analysis (one for each Phase) but it's not allowed to map more than one analysis to the same output attribute (Setpoint-Future-Value).
Any idea ?
