Applications & Features

Industrial Ethernet access

The processor adds one 10/100/1000 Mbps RJ45 Industrial Ethernet interface to a compatible S7-1500 station.

Integrated security

VPN, firewall and IEEE 802.1X functions support segmented and authenticated industrial network designs.

Protocol coverage

TCP/IP, ISO, UDP and S7 communication support controller, service and data-exchange applications.

Network services

SNMPv1/v3, DHCP, FTP client/server, email, IPv4/IPv6 and NTP provide diagnostics, file exchange and time synchronization.

Connections

Industrial Ethernet	One RJ45 jack supports 10, 100 or 1000 Mbps operation.
Backplane bus	The module receives 15 V supply from the compatible S7-1500 backplane bus.
Network protocols	Configure only the required TCP/IP, ISO, UDP, S7, broadcast or multicast services for the application.
Security functions	Use the documented VPN, firewall and 802.1X settings within the plant cybersecurity design.
Engineering	Confirm the required firmware, configuration package and S7-1500 CPU compatibility in the current Siemens documentation.

Installation

01 - Verify the exact article number

Match 6GK7543-1AX10-0XE0 on the quotation, module label, packaging and Siemens product record.

02 - Check station compatibility

Confirm the S7-1500 rack, CPU, firmware and engineering software support the CP 1543-1 version being installed.

03 - Reserve module space

Allow for the 35 x 142 x 129 mm module envelope, front RJ45 access and cable bend radius.

04 - Install in the rack

De-energize the station, mount the module in the supported S7-1500 rack position and seat the backplane connection correctly.

05 - Commission network security

Configure addresses, protocols, firewall, VPN, authentication, diagnostics and NTP according to the approved network design.

Environment

Horizontal installation

Operating ambient temperature -30 to +60 degrees C.

Vertical installation

Operating ambient temperature -30 to +40 degrees C.

Storage and transport

-40 to +70 degrees C.

Humidity

Up to 95 percent relative humidity at 25 degrees C, without condensation.

Protection

IP20; install in a suitable control cabinet for the application.

Contaminants

Corrosive-gas testing is specified according to ISA-S71.04 severity levels G1, G2 and G3.

FAQ

Q1. How can the exact quoted 6GK7543-1AX10-0XE0 be verified?

Match the complete 6GK7543-1AX10-0XE0 article number on the quotation, Siemens label and packaging. Confirm CP 1543-1, one gigabit RJ45 interface and the -1AX10-0XE0 suffix.

Q2. How can New, Used or Refurbished condition be distinguished?

Request date-marked photos of the nameplate, RJ45 jack, front indicators, backplane connector, housing, rack latch and seals. Check connector wear, scratched contacts, repaired plastic, changed labels and non-original packaging.

Q3. How should supplier legality and reliability be checked?

Verify the supplier legal entity, registered address, payment beneficiary and traceable sales contact. The offer must state Siemens, 6GK7543-1AX10-0XE0, CP 1543-1, condition and quantity.

Q4. Which specifications must engineering confirm before purchase?

Confirm S7-1500 rack and CPU compatibility, firmware and engineering support, one RJ45 gigabit interface, required security services, 15 V backplane supply, 35 x 142 x 129 mm space, 260 g weight and installation orientation.

Q5. What physical evidence should be requested before payment?

Ask for one date-marked photo set showing the complete Siemens label, -1AX10-0XE0 suffix, RJ45 port, indicators, backplane connector, mounting latch, seals and original packaging.

Q6. Can 6GK7543-1AX00-0XE0 replace 6GK7543-1AX10-0XE0?

Not automatically. The -1AX00 predecessor has different hardware and published electrical data. Confirm firmware, engineering support, ambient limits, current consumption and project security configuration before substitution.
