We have a Parker DC590+ connected to a Parker TS8003 HMI.
In the HMI program, the displayed values of the START(C3) and DRIVE START parameters (Tags 68 & 82) remain at OFF even though they must be ON/TRUE because start is initiated via the physical C3 input, the contactor is closed and the motor is running. Strangely, the CONTACTOR CLOSED parameter (Tag 83) does go to ON.
I have tried displaying the parameters directly (as a Status Text object with 590 as the data source) and as a Data Tag but both stubbornly remain OFF.
Are START(C3) and DRIVE START momentary signals that would not be seen by the HMI, or do I need to configure something else in order to read their values?
