Specialty Modules

The module/submodule types are listed for the special-purpose modules and the
substitute I/O modules assigned in the tables below.
The subsequent tables for the submodule types and data lengths list the number of
data bytes provided in the respective process image for the individual submodules.
The respective number of bytes of the telegrams in the send and receive direction
is also specified as input IODIOC (provider) and output IOCIOD
(consumer).

Up/Down Counter

The group of up/down counters has two module types divided into three
submodule types.
Table 85: Module types – Up/Down Counter
Module type
1(2)CNT
2CNT
For up/down counters, provider and consumer status (IOPS, IOCS) of the input or
output information are exchanged between the IO controller and IO device in both
directions.
