Specialty Modules

In addition to the data bytes, the control/status byte is also displayed for select
I/O modules. This byte is used for the bi-directional data exchange of the I/O
module with the higher-level control system.
The control byte controls the I/O module's behavior and operation. The status
byte reports the I/O module's status. It is possible to set the counter with the
control byte or indicate a range overflow/underflow with the status byte.
The control/status byte always lies in the low byte for the fieldbus
coupler/controller with EtherNet/IP.
Information for the control/status byte development
Please refer to the corresponding description of the I/O modules for the structure
of the control/status bytes. You can find a manual with the relevant I/O module
description at: http://www.wago.com.
The specialty modules represent analog input/output modules.
Therefore, their process input values also occupy one instances per channel in
the "Analog Input Point Object" (class 0x67) and their process output values one
instance per channel in the "Analog Input Point Object" (class 0x68).

Serial Interfaces with Alternative Data Format

The process image depends on the parameterized operating mode!
The operating mode of the configurable I/O module can be set. Based on the
operating mode, the process image of these I/O modules is then the same as
that of the respective version.
The I/O modules with serial interface that are set to the alternative data format
occupy 4 bytes of user data in the input and output area of the process image, 3
data bytes and one additional control/status byte. Two words are assigned in the
process image via word alignment.

The specialty modules represent 2x2 bytes and occupy 2 instances in class
(0x67) and 2 instances in class (0x68).
