Weintek register types

Hello,

Currently I am working with a Weintek HMI for a project. According to the manual there are bit and word registers available (see attachment).

I understand the LB (Local Bits), LW (Local Words) and RW (Retentive Words). However, what do they mean with the following types:

• LW_Bit
• RBI
• RW_Bit
• RW_A_Bit
• RW_A
• RWI

Any help would be appreciated. With best regards.
