I have a question regarding Zhejiang Zhongkong interlocking systems, and I’d like to ask the experts for their advice!

I’ve been learning the configuration programming for the *Zhejiang University Zhongkong JX300XP recently, and it seems fine so far. However, I’m not quite understanding the concepts related to FLOAT, INT, LONG, SFLOAT, SINT, and ULONG in the graphic editing section. If I want to use pressure to control the opening and closing of a shut-off valve, what type of data should I use? I’m also not quite sure how to work with 1 byte, 2 bytes, 4 bytes, and 8 bytes in variables. I would be very grateful if experts could give me some guidance! Thank you so much! ! !
By default, the value in the pressure group is SFLOAT; valve switching involves more complexity, requiring a 1-byte boolean value and a 2-byte SINT.
If a pressure interlock is used to control a shut-off valve, what parameter should be used? The pressure analog signal can be directly connected to a half-precision floating-point module for comparing values; an additional byte is used as a interlock switch, and finally a cut-off valve is connected, using an R coil
If half-precision floating-point values are used as interlock points, they need to be converted to floating-point numbers, multiplied by the range, and then compared with the interlock value
