Figure 118: Writing to the Bit Register
The Mask is only used when WRITING to the 32-bit parameter, BitRegister.#.Value. When reading the 32-bit value, all bits are
read regardless of the mask.
Figure 119: Bit Read/Write Process
Configuring the User Bit Mask Register
The Bit Mask is a 32-bit parameter that can be configured through Power Tools Pro, in the User Program, or over the
communications network. The default value for the Mask register is 0xFFFFFFFF (HEX), or all bits ON. To change the Mask
value using PowerTools Pro, navigate to the Mask tab on the Bits view, see Figure 120.
