Overview Manuals PROFINET Roles Open Communication Network Services Product Applications

Features:

  • Dual-port interface: two 100 Mbit RJ45 connections on one switched Ethernet interface
  • Flexible PROFINET role: operation as IO Controller or IO Device
  • Protocol coverage: TCP/IP, ISO-on-TCP, UDP, S7 communication, SNMPv1, and NTP
6GK7542-1AX10-0XE0 expands an S7-1500 system with a dedicated PROFINET communications path rather than additional process I/O.

Its dual-port switch supports line wiring while the logical resource is still one Industrial Ethernet interface.

The distinction between CM and CP is part of the product identity and should remain intact in the hardware configuration.

  • IO Controller: the module can manage assigned PROFINET IO devices.
  • IO Device: it can also present the S7-1500 station to another controller.
  • Configuration: the selected role is established in the engineering project.
  • Identity: Siemens names the hardware CM 1542-1.
  • TCP/IP: supported for open user communication.
  • ISO-on-TCP: available through the documented T-block resources.
  • UDP: supported alongside IP broadcast and multicast.
  • S7 communication: provided as a separate Siemens communication service.
  • Port layout: two RJ45 ports form an integrated switch.
  • Device management: SNMPv1 is supported.
  • Time service: NTP can synchronize the module clock.
  • Media rate: each electrical connection operates at 100 Mbit/s.
  • S7-1500 PROFINET expansion: add an IO Controller or IO Device role to the station.
  • Open Ethernet communication: exchange user data with TCP/IP, ISO-on-TCP, or UDP.
  • Managed plant networking: integrate SNMPv1 monitoring and NTP time synchronization.
  • Redundant system communication: apply the Siemens-supported redundancy functions in the documented topology.
Description
Designed as a SIMATIC NET communications module, 6GK7542-1AX10-0XE0 connects an S7-1500 controller to PROFINET as an IO Controller or IO Device. The two integrated RJ45 ports form one Industrial Ethernet interface, so the module can sit naturally in a line topology without being misidentified as a separate CP product.

Open communication through 6GK7542-1AX10-0XE0 includes TCP/IP, ISO-on-TCP, and UDP, while S7 communication supports controller data exchange. IP multicast and broadcast, SNMPv1, and NTP time synchronization add network-management functions that are useful when the module is engineered as part of the plant communications design.

The compact S7-1500 format of 6GK7542-1AX10-0XE0 is powered from the backplane and supports redundancy features stated in the Siemens data. Actual connection counts remain subject to CPU and system limits, which keeps network capacity tied to the real project rather than the module headline alone.

Technical notes
6GK7542-1AX10-0XE0 is a CM 1542-1 with one switched Industrial Ethernet interface and two 100 Mbit RJ45 ports; it is not the CP 1542-1. Using the wrong device family can invalidate the hardware catalog and network design, so match the CM designation and complete order number before loading the project.

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.
Should 6GK7542-1AX10-0XE0 be configured as a CP 1542-1?
No. Siemens identifies the article as CM 1542-1. Select that exact hardware entry in the S7-1500 project so the supported functions and resources match the installed module.
Can 6GK7542-1AX10-0XE0 act as a PROFINET IO Device?
Yes. Siemens supports both IO Controller and IO Device roles. The project must assign the intended role and the corresponding network relationships before commissioning.
Do the two RJ45 ports on 6GK7542-1AX10-0XE0 represent two independent Ethernet interfaces?
No. They are two electrical ports on one switched Industrial Ethernet interface. Design addressing and diagnostics around that single logical interface.
Which open protocols are available through 6GK7542-1AX10-0XE0?
The documented set includes TCP/IP, ISO-on-TCP, and UDP. Choose the appropriate T-block communication and stay within the CPU-dependent connection resources.
Can 6GK7542-1AX10-0XE0 synchronize time from the plant network?
Yes. NTP time synchronization is supported. Provide the correct NTP server and network path in the engineered configuration rather than assuming time is set automatically.
What limits the number of connections available on 6GK7542-1AX10-0XE0?
Siemens states module capacities, but the usable total also depends on the CPU and system upper limits. Size the project with the installed controller and all communication services included.
