WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
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
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

Parameters
Parameters for DI 16x24VDC ST
The effective range of the configurable parameters depends on the type of configuration.
The following configurations are possible:
●Central operation with an ET 200SP 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 section Parameter assignment
and structure of parameter data record (Page 24).
The following parameter settings are possible:

If you use a floating s
witch, 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).

Due to the limited number of parameters with a maximum of 244 bytes per ET 200SP station for a PROFIBUS GSD
configuration, the configuration options are restricted. If required, you can assign these parameters using data rec-
ord 128 as described in the "GSD file PROFINET IO" column (see table above). The parameter length of the I/O module
is 4 bytes.

4.2
Declaration of parameters
Diagnostics: No supply voltage L+
Enabling of the diagnostics for no or insufficient supply voltage L+.
Diagnostics: Wire break
Enabling diagnostics if the line to the encoder is interrupted.
Channel activated
Determines whether a channel is activated or deactivated.
Input delay
This parameter can be used to suppress signal interference. Changes to the signal are only
detected if they are constantly pending longer than the set input delay time.
Potential group
A potential group consists of a group of directly adjacent I/O modules within an ET 200SP
station, which are supplied via a common supply voltage.
A potential group begins with a light-colored BaseUnit through which the required voltage is
supplied for all modules of the potential group. The light-colored BaseUnit interrupts the
three self-assembling voltage buses P1, P2 and AUX to the left neighbor.
All additional I/O modules of this potential group are plugged into dark-colored BaseUnits.
You take the potential of the self-assembling voltage buses P1, P2 and AUX from the left
neighbor.
A potential group ends with the dark-colored BaseUnit, which follows a light-colored
BaseUnit or server module in the station configuration.

Configuration options of DI 16x24VDC ST
You can configure the module with STEP 7 (TIA Portal) or with a GSD file. If you configure
the module by means of a GSD file, the configurations are available under various short
designations/module names; see the table below. The following configurations are possible:

Evaluating the value status
An additional two bytes are allocated in the input address space if you enable the value
status for the digital module. Bits 0 to 15 in these bytes 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 deactivated or there is a fault on the module.
If a fault occurs on a channel with this module, the value status for all channels is 0.
