PRODUCT OVERVIEW

SIMATIC CM 1542-1

PROFINET communication expansion for S7-1500 systems

The SIEMENS 6GK7542-1AX00-0XE0 is a CM 1542-1 communication module that adds a PROFINET interface with an integrated two-port RJ45 switch to an S7-1500 station. It supports PROFINET IO controller/device roles and open communication services.

Additional PROFINET interface
Provides an independent Industrial Ethernet interface for PROFINET IO and S7-1500 communication tasks.

Integrated two-port switch
Two galvanically isolated RJ45 ports support 10/100 Mbit/s Fast Ethernet and line or ring integration.

Open communication services
Supports TCP, ISO-on-TCP, UDP, S7 communication, IP broadcast/multicast, SNMPv1, and NTP time synchronization.

Applications

PROFINET COMMUNICATION

Applications

Additional Industrial Ethernet connectivity for S7-1500 systems

PROFINET IO controller
Operate a separate PROFINET IO system through the CM interface within the documented resource limits.

PROFINET IO device
Integrate the S7-1500 station as an IO device where the project architecture requires this role.

Open user communication
Use TCP, ISO-on-TCP, or UDP connections for programmed communication services.

Network integration
Apply the integrated two-port switch for line or MRP ring topology and managed S7-1500 network designs.

Installation

S7-1500 INTEGRATION

Installation

Hardware, network, and project checks before commissioning

Check CPU resources
Confirm that the selected S7-1500 CPU supports the required number of communication modules and connection resources.

Mount on the S7-1500 rail
Install the CM in the documented station position and connect it through the backplane bus.

Connect Industrial Ethernet
Use the RJ45 ports for the planned line or MRP topology and observe the permitted Ethernet cable lengths.

Configure in STEP 7
Assign the device, interface, IP, PROFINET role, connections, and diagnostics in the supported engineering environment.

Verify network operation
Check duplicate-address handling, port status, PROFINET communication, time synchronization, and diagnostics before release.

Selection

ARTICLE-NUMBER CHECK

Selection

Confirm firmware generation, network role, and S7-1500 resources

Confirm the full order code
The quotation, module label, and documentation should all show 6GK7542-1AX00-0XE0.

Verify the hardware generation
This article is the CM 1542-1 hardware associated with firmware V3.0; later article numbers require separate review.

Define the PROFINET role
Confirm whether the project uses the CM as an IO controller, IO device, or for open communication.

Check network requirements
Validate two 10/100 Mbit/s RJ45 ports, topology, cable length, IP plan, and required protocols.

Review CPU and project limits
Confirm module count, connection resources, STEP 7 support, backplane power, and cabinet space before ordering.

FAQ

BUYER AND ENGINEER CHECKLIST

FAQ

Six model-specific questions for supplier and product verification

Q1 · How can a buyer verify the exact CM 1542-1 being quoted?

Match 6GK7542-1AX00-0XE0 on the quotation, module nameplate, packaging, and current photographs. The unit should be a CM 1542-1 with one PROFINET interface and two RJ45 Fast Ethernet ports.

Q2 · What evidence helps distinguish new stock from used or refurbished equipment?

Request time-stamped images of the front, nameplate, both RJ45 ports, backplane connector, housing, LEDs, mounting points, and packaging. Ask whether the module has been installed, powered, repaired, or firmware-updated.

Q3 · How can procurement assess supplier competence?

A qualified supplier should state the IO controller/device roles, two 10/100 Mbit/s RJ45 ports, 15 V backplane supply, IP20 protection, 35 × 147 × 129 mm dimensions, and approximately 400 g weight.

Q4 · Which engineering checks are required before purchase?

Confirm the S7-1500 CPU, STEP 7 project, firmware generation, available communication resources, required PROFINET role, IP plan, topology, port settings, cable lengths, and cabinet space.

Q5 · What should be requested before payment?

Ask for current nameplate and port photographs, the backplane connector, housing, packaging, quantity, and traceability. Independently verify the supplier identity and payment beneficiary.

Q6 · Can 6GK7542-1AX10-0XE0 or another CM suffix replace this article?

Not automatically. Hardware, firmware, environmental data, project support, and module behavior can differ. Approve a successor only after the CPU, STEP 7 project, network design, and spare-parts policy are reviewed.
