Application Information

This document will demonstrate the following:

  • Show compatibility of FB44 with existing FB34 project by performing a bus node swap.
  • Set up FB44 project and demonstrate the new functions of the bus node.
Commissioning With Siemens TIA Portal: Create Project
  • Create New Project.
  • Select Create after entering project name.
  • Select Open the project view.
Installation of GSD files for Festo Library
  • Navigate to Menu Command for Options > Manage General Station Description Files (GSD).
  • Navigate to the directory containing the GSDML file. Please extract contents first.
  • Select the GSDML file by checking the box.
  • Install.
Commissioning with Siemens TIA Portal: Configure the CPU
  • In the Project tree, click “Add new device”.
  • For this example, select CPU 1214C DC/DC/DC. Expand the list and select 6ES7 214-1AG40-0XB0 (V4.4).
  • Click “OK” to add the CPU.
Configure Siemens CPU
  • Click “Add new subnet” within the General parameters tab and accept PN/IE_1.
  • Enter the IP address and Subnet mask for the CPU.
  • Save Project.
Add Festo CPX Terminal

• In the Project tree, double-click “Devices & networks”. You should see your CPU with PN/IE_1 assigned.

  • In the Hardware catalog, locate CPX Rev 30 by expanding the products.
  • Drag and drop CPX Rev 30 into the Network space to the right of the CPU.
Connect Network of CPU and Festo CPX Terminal

• Using your cursor, grab the end of PLC PN/IE_1 and drag it to the CPX.

  • Now the Profinet communication network is connected between devices.
Hardware Configuration: Add CPX Modules
  • Double-click on the CPX from the Network View.
  • Using the Catalog, drag and drop CPX modules accordingly.
  • Check for PN/IE_1 Subnet and input IP address information.
Review and Setup of I/O Tags

• Review the addressing for each module.

  • Add any tags you feel are needed.
Create Watch/Force Table

• Click “Add new watch table”, then enter the tag name you created. Drag the lower right corner to auto-copy.

  • Save Project.
  • Right-click PLC_1 and select “Compile>Hardware and software (only changes)”.
Compile Hardware and Software Download
  • Compile hardware and software.
  • You should see no errors. Some warnings are normal and can be resolved.
  • Download Project, Go Online, make sure PLC is in RUN mode.
Confirmation of I/O Signals PLC to Festo CPX Terminal

• Open the Watch Table and click the “Monitor All” glasses. Notice the Monitor value shows state.

  • Change a value by typing a “1” into the Modify value box.
  • Select the “Modify All” button to force the value.
  • Confirm the solenoid LED turns ON.
Swap in FB44 Profinet Node
  • Go Offline with the PLC, then power OFF the CPX.
  • Remove the FB34 bus node using T10 torx. Replace with FB44 bus node, tighten screws.
  • Set the DIL switches same as FB34, reconnect network cable then power ON the CPX.
  • Use Festo Maintenance Tool to confirm IP address settings, then close FMT.
Test Swap-In Feature of FB44
  • Go Online with PLC and confirm no errors.
  • System should accept the FB44 bus node even though the project is set up for FB34.
  • Re-test forcing of solenoid valves to confirm functionality.

Commissioning of FB44 Profinet Node
  • Complete the steps to create a new project using the same PLC.
  • Set the FB44 DIL switches to Remote I/O and I/O Diagnostics interface ON.
  • When adding the CPX Terminal to the Network view, use Rev.50.
  • Drag and drop PN/IE_1 network to CPX.

Hardware Configuration: Add CPX Modules
  • Double-click on the CPX from the Network View.
  • Using the Hardware Catalog, drag and drop CPX modules accordingly. Notice (4) new features of the FB44 bus node to add.
  • Check for PN/IE_1 Subnet and input IP address information.
Compile Hardware and Software Download
  • Compile hardware and software, then download Project and go Online.
  • You should see no errors. Some warnings are normal and can be resolved.

Note: If no errors on FB44 are active but the project has errors, disconnect the network cable from the CPX-FB44 and cycle power to the PLC. Go online with the PLC without CPX being connected, then plug the network cable back in.

Review of FB44 I/O Diagnostics Interface
  • The new FB43/44/45 Profinet bus nodes have four new features:

1. Voltage Measurement: ability to monitor PS & PL supply voltage.*

2. MRPD (Media Redundancy for Planned Duplication): allow for a Ring Topology.

3. NTP Time Sync: allow the CPX to see real-time clock values.

4. S2 System Redundancy: ability to use a redundant PLC for process stability

*Note: This document will only review the Voltage Measurement feature.

  • In the Watch Table, notice the Power Supply (PS) and Power Load (PL) variables listed as an Input Word (%IW). These are monitoring the DC input voltage and can be seen by the PLC in real time.

The error shown below was created by a short in the CPX Input module.

  • Review Status bits: bit 2 & bit 5 ON indicate Short Circuit on Input (0010_0100).
  • Review of Diagnostics Interface: 16#2400.
Commissioning With Siemens TIA Portal: Primary Setup Tool
  • A helpful Siemens utility called Primary Setup tool is also available to scan, verify and modify network address and node name data.


  • If bus faults occur, verify communication by pinging the address of each using the PC command prompt.
