I want to create an IO Field in KTP700 basic HMI that will be used to set an analog value setpoint to a Logosoft 8.3 project. I have created the IO Field and set the HMI tags in such a way that it works good. When I enter a value in the IO Field it automatically updates the value of an Analog Input in the Logosoft Project. My only problem is that I want to set a start value in order when the LOGO PLC and the KTP700 basic HMI are powered on, the initial value to be preset and not zero. I have set the 'Start Value' for the specific tag in TIA Portal but it is not working well, i.e. when the PLC and HMI are powered on the value is '0' (both in HMI IO Field and in Logosoft project). If I disconnect the HMI from the PLC (i.e. remove the LAN cable) and I power it on, then the value in the IO Filed of the HMI is correct, as set in the 'Start Value' field of the HMI tag. It seems that when the HMI is connected on the PLC, for some reason it does not load the 'Start Value' neither on the HMI IO Field, nor in the PLC corresponding analog input. Attached self explanating photos and screenshots for the above issue. How can I set the IO field in order to load the preset value and trasnfer it to the LOGO PLC on power on?
