Product details

What this CP does in the rack

The Siemens 6GK7543-1MX00-0XE0 is a communication processor for the S7-1500 system, supporting DNP3 and substation protocols alongside SNMP management. It sits in a double-wide slot and needs TIA Portal V14 SP1 or higher. Supply voltage 20.4–28.8 V DC, 0–70 °C operation.

What it doesn't do (routing)

This module does not handle PC or BGP routing. It supports automation protocols: DCP for discovery, NTP for time sync, LLDP for topology, plus DNP3 and substation protocols. For WAN routing, use a separate router.

Panel fit

Double-wide S7-1500 format, one per CPU. Mounts in the backplane; 70 mm wide, 147 mm tall, 129 mm deep. No separate aux power needed – picks up from the rack. Just make sure your TIA Portal is V14 SP1 or newer.

Frequently asked questions

What is the required software to configure this module?

You need STEP 7 Professional V14 SP1 (TIA Portal) or higher.

Does the 6GK7543-1MX00-0XE0 support PC or BGP routing?

No, PC and BGP are both listed as 'No' in the specifications. This is not a routing module; it's for automation communication.
