These modules present themselves with 1x6 bytes, so that the object 0x3200
for 6 byte Special Modules, Inputs is used. Therefore for each module one
Subindex is occupied.

These modules present themselves with 1x6 bytes, so that the object 0x3300
for 6 byte Special Modules, Outputs is used. Therefore for each module one
Subindex is occupied.

The above Counter Modules have a total of 6 bytes of user data in both the In-
put and Output Process Image (4 bytes of counter data and 2 bytes of con-
trol/status). The two counter values are supplied as 16 bits. The following ta-
bles illustrate the Input and Output Process Image, which has a total of 6 bytes
mapped into each image.
