Process Data Architecture for CANopen
WAGO-I/O-SYSTEM 750
CANopen
These modules present themselves with 2x2 bytes, so that the object 0x6401
(also 0x2400 possible) for 2 byte Special Modules, Inputs and the object
0x6411 (also 0x2500 possible) for 2 byte Special Modules, Outputs are used.
Therefore for each module two Subindices are occupied.
MP Bus Master Module
750-643
The MP Bus Master Module has a total of 8 bytes of user data in both the In-
put and Output Process Image (6 bytes of module data and 2 bytes of con-
trol/status). The following table illustrates the Input and Output Process Im-
age, which have 8 bytes mapped into each image.

Data bytes
These modules present themselves with 1x8 bytes, so that the object 0x3600
for 8 byte Special Modules, Inputs and the object 0x3700 for 8 byte Special
Modules, Outputs are used. Therefore for each module one Subindex is
occupied.
