Trying VM mapping on an analog amplifier block to display on a SIMATIC HMI. The PLC is a LOGO 0BA1 programmed on LogoSoft 8.3. The HMI is KTP700 basic. If the analog amplifier range is 0~2000 then the mapping works fine and the indication on the HMI corresponds on the corresponding AI of the LOGO. However when I set the range of the analog amplifier to -250~2000, then the HMI indication becomes eratic. Specifically, with 0V on the 0-10V AI the reading of the HMI is 65286. It seems that there is a problem when setting negative values in the Analog amplifier's range. How can I set the parameters in order to read an AI range of -250~2000 o the SIMATIC HMI?

Good morning and thanks for your reply! When trying to change the Pattern from 99999 to s9999, there is no such options. I have only option to change from 1 digit (i.e. 9) up to 6 digits (i.e. 99999) but no option for letter to set s9999. Furthermore this applies only to IO Field. Bargraph (which also displays wrong value) does not have such an option (pattern change). I tried setting the IO Field pattern from 99999 to 9999 but then the result was #### indication after loading the program to the HMI (See attached).
