expression I am using is
tag({operators_path}+ "CECOEL" +"/REG_ZON_CCGT/SRS/"+{TagName})
when I am restarting the gateway very first time then my expression tag value is becoming -1 from nowhere, the value of tag({operators_path}+ "CECOEL" +"/REG_ZON_CCGT/SRS/"+{TagName}) can never be -1, its either 0 or 1.
I am suspecting that if the dependent tag ( i.e tag({operators_path}+ "p1" +"/path/to/"+{TagName}) ) is not set to defined value then this behaviour is happening.
Anyone know about this?
