CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will

Parameters
Parameters for DI 8x24VDC ST
The effective range of the parameters depends on the type of configuration. The following
configurations are possible:
●Central operation with an S7-1500 CPU
●Distributed operation on PROFINET IO in an ET 200SP system
●Distributed operation on PROFIBUS DP in an ET 200SP system
When assigning parameters in the user program, use the "WRREC" instruction to transfer
the parameters to the module using the data records; refer to the section Parameter
assignment and structure of the parameter data record (Page 23).
The following parameter settings are possible:

If you use a simple switch, you need to connect a resistor in parallel so that the wire break diagnostics is
enabled in the open state (sensor resistance for the wire break diagnostics: 25 kΩ to 45 kΩ).
2
Due to the limited number of parameters at a maximum of 244 bytes per ET 200SP station with a
PROFIBUS GSD configuration, the configuration options are restricted. If required, you can assign these
parameters using data record 128 as described in the "GSD file PROFINET IO" column (see table above).
The parameter length of the I/O module is 16 bytes.

4.2
Explanation of the parameters
Diagnostics no supply voltage L+
Enabling of the diagnostics for no or insufficient supply voltage L+.
Diagnostics short-circuit to ground
Enabling of the diagnostics if a short-circuit of the encoder supply to ground occurs.
Diagnostics wire break
Enabling of the diagnostics if the module has no current flow or the current is too weak to
be measured at the relevant input.
Operating mode
Determines whether a channel is enabled or disabled.
Input delay
This parameter can be used to avoid signal faults. Changes to the signal are only detected
if they are constantly pending longer than the set input delay time.
Potential group
Specifies that a BaseUnit with voltage supply feed-in is located in this slot (see system
manual ET 200SP distributed I/O system
(http://support.automation.siemens.com/WW/view/en/58649293)).

Address space
Configuration options
The following configurations are possible:
●Configuration 1: Without value status
●Configuration 2: With value status
Evaluating the value status
An additional byte is allocated in the input address space if you enable the value status for
the digital module. Bits 0 to 7 in this byte are assigned to a channel. They provide
information about the validity of the digital value.
Bit = 1: No fault is present on the channel.
Bit = 0: Channel is disabled or there is a fault/error on the module.
If a fault/error occurs on a channel with this module, the value status for all channels is 0.
Address space
The following figure shows the assignment of the address space for the DI 8×24VDC ST with
value status (Quality Information (QI)). The addresses for the value status are only available
if the value status is enabled.
