- NOTE**: it is the bit of MDx[1] used for I/O scanner table entry 17 to 32, not MDx[0].
Bit number: Bit 0 is a low bit counting from right side.
Example:
If users configure %MD1:4 as device control block, %MD1[0] bit 31 can enable/disenable I/O scanner table entry 1. %MD1[1] bit 15 can enable/disenable I/O scanner table entry 17.
- NOTE**: it is the bit of MDx[1] used for I/O scanner table entry 17 to 32, not MDx[0].

Bit number: Bit 0 is a low bit counting from right side.
Example:
If users configure %MD1:4 as device control block, %MW2 bit 15 can enable/disenable I/O scanner table entry 1. %MW3 bit 15 can enable/disenable I/O scanner table entry 17.
Schneider will correct the documentation -- Modicon Quantum with Unity Ethernet Network Modules User Manual to match the current implementation.
