More Information

Overview Manuals Backplane Exchange PROFIBUS Role Service Communication Environmental Design

Features:

  • The S7-1500 backplane supplies data and operating power.
  • One RS485 interface carries the configured PROFIBUS DP network.
  • Conformal coating and extended temperature limits define the SIPLUS construction.
The module passes process and service communication between the CPU and the PROFIBUS segment.

Its configured master or slave role determines whether it coordinates DP devices or exchanges data under another master.

Bus wiring, termination and station addressing remain external installation responsibilities.

The Siemens 6AG1542-5DX00-7XE0 SIPLUS CM 1542-5 PROFIBUS Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Connecting the CPU with the communication module

  • Power source: The S7-1500 backplane supplies the module rather than a separate front 24 V input.
  • CPU path: Configuration and process data move between the CPU and CM through the backplane.
  • Slot assignment: The STEP 7 hardware configuration must place the exact module in the selected rack position.
  • Project download: The CPU stores and transfers the assigned CM parameters during commissioning.

Defining how the station participates on PROFIBUS DP

  • DP master: The configured module coordinates data exchange with assigned DP slaves.
  • DP slave: The module can present the S7-1500 station as a DP slave under an external master.
  • Bus speed: All stations on the segment use the compatible configured transmission rate.
  • Addressing: The project and the network plan must assign one unambiguous PROFIBUS address.

Sharing the bus with engineering and S7 services

  • S7 communication: Supported S7 connections exchange controller data through the PROFIBUS path.
  • PG/OP access: Engineering or operator devices can use the documented communication service.
  • Time synchronization: The module can pass the configured time service between the bus and station.
  • Diagnostics: CPU and bus diagnostics identify module, station and network conditions separately.

Applying SIPLUS construction without changing bus rules

  • Coating: Conformal coating protects the documented board surfaces against the specified environment.
  • Temperature: The SIPLUS version carries the extended operating and startup temperature limits.
  • Connector boundary: The front RS485 D-sub carries communication signals but no 24 V field-device supply.
  • Termination: The physical ends of the PROFIBUS segment still require correct termination and cable routing.
Description
The conformal-coated Siemens 6AG1542-5DX00-7XE0 operates as a SIPLUS S7-1500 CM 1542-5 communication module for PROFIBUS DP. It transfers controller data between the backplane and one RS485 PROFIBUS network while acting in the configured DP master or DP slave role.

Installed beside the CPU, 6AG1542-5DX00-7XE0 receives its operating power through the S7-1500 backplane. The front 9-pin D-sub carries the PROFIBUS signals, so field-device power remains a separate part of the station wiring.

The project downloaded through the CPU defines the bus address, transmission rate and communication role of 6AG1542-5DX00-7XE0. S7 and PG/OP services then share the same PROFIBUS interface with the configured DP exchanges.

Conformal coating and the extended temperature design distinguish 6AG1542-5DX00-7XE0 from its base CM hardware. Those environmental features do not change the need for matching bus termination, connector wiring and STEP 7 configuration.

Technical notes
The CPU supplies Siemens 6AG1542-5DX00-7XE0 through the S7-1500 backplane; its PROFIBUS connector does not provide a field-device 24 V supply. Configure the same master or slave role in the project and on the connected bus.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Does 6AG1542-5DX00-7XE0 need a separate 24 V terminal supply?
No. The 6AG1542-5DX00-7XE0 receives operating power from the S7-1500 backplane; the front PROFIBUS connector does not supply 24 V to field devices.
Can Siemens 6AG1542-5DX00-7XE0 operate as both PROFIBUS roles at once?
Siemens 6AG1542-5DX00-7XE0 supports DP master and DP slave operation, but the active role and exchanges must follow the configured STEP 7 project rather than being assumed automatically.
Why does the exact 6AG1542-5DX00-7XE0 project entry matter?
The 6AG1542-5DX00-7XE0 is the SIPLUS conformal-coated variant based on specific CM hardware, so the rack project must identify the correct module and firmware family.
What should be checked when 6AG1542-5DX00-7XE0 cannot reach a DP station?
For 6AG1542-5DX00-7XE0, verify the configured role, bus address, transmission rate, connector wiring, cable termination and the DP station assignment before replacing hardware.
Does conformal coating change the PROFIBUS wiring of Siemens 6AG1542-5DX00-7XE0?
No. The coating and extended temperature design of Siemens 6AG1542-5DX00-7XE0 do not change RS485 pinning, segment termination or the need for a matching bus configuration.
