Bit Mapping Rules
The bit mapping for a G3 manifold varies with the physical configuration of the manifold. The following is a
breakdown of the bit mapping rules associated with the Aventics valve manifold.
Valve Side
1)
Solenoid coil outputs are connected to the valve coils using the Z-Boards
2)
The valve solenoid coil output portion of the total output size is adjustable from 0 to 4 bytes.
3)
Solenoid coil output addressing begins at the 1
if applicable, the "12" coil, and continues in ascending order away from the communication node.
4)
Each manifold station allocates 1 or 2 output bits. This is dependent on the Z-Board
A single Z-Board
5)
Z-Boards
can be used in any arrangement (all singles, all doubles, or any combination) as long as output
™
group No. 1 and output group No. 2 bits do not overlap (i.e. combinations of Z-Boards
physical configuration of the manifold could exceed the output capacity.
NOTE!
Discrete I/O Side
Outputs
1)
The Sub-Bus output byte size portion is self-configuring in byte increments, after an output module is installed
on the Sub-Bus and power is applied.
2)
Outputs are mapped consecutively by module. The output bits from the 1
the bits from the valve coils. The output bits from the second module will be mapped directly after the output
bits from the 1
Inputs
1)
The Sub-Bus input byte size portion is self-configuring in byte increments, after an input module is plugged into
back plane and power is applied.
2)
Inputs are mapped consecutively by module. The input bits from the 1
input bits from the second module will be mapped directly after the input bits from the 1
