Component Functions
If a length is specified in the CIP object, write access takes place. If length 0 is specified, read access takes
place. In case of an error, an error code and an extended error code are returned. The error code can be
found in the system information. The extended error code describes the error in accordance with the IO-
Link interface specification.
The CIP object must be provided with the following parameters:
Message type
Service type
Service code
Instance
Class/object
Attribute
Source length
6.6 DI Module Functions
Status of the Input Ports via Process Data
The status of each input (valid signal on/valid signal off) can be read via process data or parameter data.
Each DI module has 8 digital inputs: 2 inputs per port.
A maximum of 6 DI modules can be installed on one terminal. Thus, up to 48 digital inputs are possible on
the compact terminal.
Status via Input Process Data:
EtherNet/IP + EtherCAT:
An input process data byte is fixed for each DI module in both variants.
--> See 5.2 "Process Data".
PROFINET:
By selecting appropriate modules/submodules (predefined in the device description file), the DI modules
can be specifically defined in the process data that is actually present.
--> See 5.2 "Process Data".
For a detailed description of the corresponding process data --> see 5.2 "Process Data".
Status via Parameter Data:
Digital input status
This parameter is used to determine the current status of each input.
