Localization of the CPU by means of LED flashing
● Reading out CPU error information
● Reading the CPU diagnostic buffer
● Reset to factory settings
● Updating the firmware of the CPU and connected modules
You can find the SIMATIC Automation Tool on the With PRONETA (PROFINET network analysis), you analyze the PROFINET
network during commissioning. PRONETA features two core functions:
● The topology overview independently scans PROFINET and all connected components.
● The IO check is a fast test of the wiring and the module configuration of a system.
You can find PRONETA on the The module has the following technical properties:
● 16 digital inputs; electrically isolated in groups of 16
● Reading M
● Rated input voltage 24 V DC
● Suitable for switches and 2-/3-/4-wire proximity switchesFirmware update V1.0.0 or higher V12 or higher X

IM 155-5 DP STThe following accessories are supplied with the module and can also be ordered separately
as spare parts:
● Labeling strips
● U connector
● Universal front door
Other components
The following component can be ordered separately:
Front connectors, including potential jumpers and cable ties
You can find additional information on accessories in the /ET 200MP This section contains the block diagram of the module and outlines various wiring options.
You can find information on wiring the front connector, creating a cable shield, etc. in the
Wiring section of the /ET 200MP The figure below shows you how to connect the module and channel addressing (input byte
a to input byte bUse the potential jumpers supplied with the front connector if you want to distribute the 24V
DC supply voltage to a neighboring module. This helps you to avoid having to terminate two
wires to one terminal.
Proceed as follows:
1. Connect the 24 V DC supply voltage to terminals 19 and 20.
2. Insert the potential jumpers between terminals 19 and 39 (L+) and between terminals 20
and 40 (M).
3. Use the terminals 39 and 40 to distribute the potential to the next module
The module can be configured differently in STEP 7; see following table. Depending on the
configuration, additional/different addresses are assigned in the process image of the inputs.
Configuration options of DI 16x24VDC SRC BA
You can configure the module with STEP 7 (TIA Portal) or with a GSD file.
When you configure the module by means of the GSD file, the configurations are available
under different abbreviations/module names.
The following configurations are possible1 x 16-channel without value status DI 16x24VDC SRC BA V12 or higher X
2 x 8-channel without value status DI 16x24VDC SRC BA S V13 Update 3 or higher
