Adding SFP Modules to Step 7/TIA

Supported Small Form-Factor Pluggables

This chapter describes how to add Small Form-Factor Pluggable (SFP) modules to the SIMATIC STEP7 or TIA Portal Automation applications to enable these applications to recognize the SFP modules in the PROFINET environment.

The following SFPs are supported for these Catalyst switches: , IE3200, and IE3300. The SFP also are supported for the fiber port expansion module. They can be added to the STEP 7 or TIA Portal Automation application installed on the supervisor.

  • GLC-T

  • GLC-TE

  • GLC-T-RGD

  • GLC-FE-100FX-RGD

  • GLC-FE-100LX-RGD

  • GLC-SX-MM-RGD

  • GLC-LX-SM-RGD

  • GLC-FE-100FX

  • GLC-FE-100LX

  • GLC-SX-MMD

  • GLC-LH-SMD

  • GLC-SX-MM

  • GLC-LH-SM

The following are the supported SFPs on IE3300 10-Gigabit Ethernet uplinks along with the 1-Gigabit Ethernet SFPs mentioned above. Note that the 10-Gigabit Ethernet SFPs are supported only on the IE3300 models supporting 10-Gigabit Ethernet interfaces.

  • SFP-10G-SR

  • SFP-10G-LR

  • SFP-10G-ER

  • SFP-10G-SR-X

  • SFP-10G-LR-X

  • SFP-10G-BXD-I

  • SFP-10G-BXU-I

  • SFP-H10GB-CU1M

  • SFP-10G-BX40D-I

  • SFP-10G-BX40U-I

Adding SFPs to the Hardware Configuration in SS7/TIA

Follow this procedure to add SFPs to the hardware configuration in STEP7 or TIA.


Note

Autonegotiation is enabled by default on the switch PHY for SFP ports upon their insertion and can be disabled using the no speed negotiate command.

Before you begin

Install the latest GSD file for your IE switches in STEP7 or TIA (see Configuring the Switch with STEP7/TIA for more information). The GSD file is not backward compatible. Combination ports do not have defaults and must be re-created in STEP7 or TIA with the new GSD file.

Procedure

Step 1

In STEP7 or TIA, open the project containing the Cisco IE switch, and double-click Devices & networks in the Project tree.

Step 2

From the Hardware catalog in the devices and network editor, select the Device Access Point (DAP) name for your switch.

Step 3

Double-click the DAP name to go to Device view tab (see callout 1).

Step 4

Expand the PN-IO row (see callout 2) in Device overview section if the port list is not displayed.

Step 5

Select the modules that you have installed in the switch from the Hardware catalog and drag them to the appropriate rows in the table area of Device view: Appropriate SFP module for port type (combo port or fiber-only port)

The following figure shows the Device view and Hardware catalog with SFP modules for IE 3400. There is an uplink module for Gi SFP. SFP GLC-FE-100FX-RGD is dragged to uplink port Gi1/1. The device in TIA is now ready to compile and download.

The following figure shows the Device view and Hardware catalog with SFP modules for IE3400 with the Fiber expansion module that has downlink SFP port Gi2/1-8, and where SFP GLC-FE-100FX-RGD is dragged to uplink port Gi2/8. The device in TIA is now ready to compile and download.

Feature History

Feature

Release / Platform

First Supported Release

PROFINET system redundancy

26.1.1

This feature enables Cisco Industrial Ethernet (IE) switches to interoperate with existing high available systems by providing robust controller failover using PROFINET S2 controller redundancy mode. It aims to minimize potential issues and downtime in the event of network or controller failures.

Read-only PROFINET

26.1.1

This feature increases device security and network flexibility by placing Discovery and Configuration Protocol (DCP) operations in read‑only mode. It:

  • Protects the IP address, gateway, and device name from changes.

  • Protects critical network settings and prevents unexpected loss of connectivity.

  • Maintains compatibility with LLDP, SNMP, and CDP.

  • Allows devices to perform identification and basic network discovery.
