1. Easy replacement

a. Using Step7 V5.x

Pre-requirement 1: S7 CPUs supporting the easy replacement feature are:

CPU S7-300: CPU 319F-3 PN/DP and CPU 319-3 PN/DP (firmware version 2.7 and upper) CPU 317F-2 PN/DP, CPU 317-2 PN/DP, CPU 315F-2 PN/DP and CPU 315-2 PN/DP (firmware version 3.1 and upper), CPU 314C-2 PN/DP (firmware version 3.3) CPU S7-400: CPU 412-2 PN and CPU 414F-3 PN/DP (firmware version 6.0) CPU 414-3 PN/DP, CPU 416-3 PN/DP and CPU 416F-3 PN/DP (firmware version 5.2 and upper) Pre-requirement 2: Molex Product Version (minimum): TBDEP-4YYP-D8U (PV 1.2.0.0) / TBDEP-

8YYP-D84 (PV 2.2.1.0) / TBDEP-4xxP-D8U-G (PV 1.2.0.0) / TBDEP-8xxP-D84-G (PV 2.2.1.0) /

TCDEP-8xxP-DxU-G (PV 2.1.3.0) / TCDEP-8YYX-DxU-01 (PV 2.1.7.0) / TCIEP-888P-D1U (PV 1.0.0.0)

Pre-requirement 3: Minimum version GSDML-V2.3-MOLEX-HARSHIO300_IP67-20140520.xml &

GSDML-V2.25-MOLEX-HARSHIO600_TCDEP-20120110.xml. Download Center.

Pre-requirement 4: In the device replacement procedure, the spare device must have no device name

when the user will swap the defective device with this spare part. If the spare device has an out-of box

device name, then use Step7 tool to perform factory reset command so that the device name will be set

to “blank” as requested.

If the above pre-requirements are fulfilled, the user can configure the device replacement mode by

checking the box “Support device replacement without exchangeable medium” as shown below:

Once done, you need to go to the topology editor. Select and highlight the PROFINET network, right

click and go to PROFINET IO Topology editor. (See below)

This topology configuration will define the Ethernet port interconnection between the Molex IO module

and the Siemens CPU. This configuration must match the real physical topology.

The figure below is an example of topology between Molex module and CPU, the port 1 of the module is

physically connected to the port 1 of the CPU.

After finishing the topology configuration, click on OK and download the configuration in the PLC.

Once the configuration is downloaded to the PLC, there is nothing else to do. The user will just need to

swap physically the defective device by the spare part without additional actions.

Note! In case of using a PROFINET Switch physically between the Molex IO module and Siemens CPU, you will need to add the GSDML of this switch in the STEP7 library (only if it does not exist in the list). Then add the Switch in the hardware configuration and then go back to topology editor to link the Ethernet ports of the Molex module and CPU to the switch the same way it’s physically connected.

b. Using TIA Portal.

b.1 Using old CPUs versions

Pre-requirement 1: In addition to S7-300 and S7-400 CPU listed in the previous paragraph, all the S7-

1200 (Firmware version < 4.1) and S7-1500 (Firmware version < 1.5) PLCs that support the device

replacement feature under TIA portal tool.

Pre-requirement 2: Molex Product Version (minimum): TBDEP-4YYP-D8U (PV 1.2.0.0) / TBDEP-





Pre-requirement 4: In the device replacement procedure, the spare device must have no device name

when the user will swap the defective device with this spare part. If the spare device has an out-of box

device name, then use TIA portal tool to perform factory reset command so that the device name will be

set to “blank” as requested.

If the above pre-requirements are fulfilled, the user can configure the device replacement mode by

checking the box “Support device replacement without exchangeable medium” as shown below:





www.molex.com 6

Once done, you need to go to the topology view. Double click on “Devices & networks” and then open

the “Topology view”. (See below)








Note! In case of using a PROFINET Switch physically between the Molex IO module and Siemens CPU, you will need to add the GSDML of this switch in the device library (only if it does not exist in the list). Then add the Switch in the hardware configuration and then go back to topology view to link the Ethernet ports of the Molex module and CPU to the switch the same way it’s physically connected.

b.2 Using new CPUs versions

Pre-requirement 1: S7-1500 PLCs with firmware V1.5 and upper and S7-1200 PLCs with firmware

V4.1 only.

Pre-requirement 2: Molex Product Version (minimum): TBDEP-4YYP-D8U (PV 1.2.0.0) / TBDEP-





In addition to the feature “Support device replacement without exchangeable medium”, the last firmware

of S7-1500 CPUs (firmware version 1.5 and upper) and S7-1200 CPUs (firmware version 4.1 only) gives

to the user the possibility to choose another option that allows the PLC to overwrite the device name of

the IO-Device. This option is called “Permit overwriting of device names of all assigned IO devices”. So

there is no longer need to fulfil Pre-requirement 3.

To configure the overwriting option in TIA portal tool, the user needs to check the box “Permit

overwriting of device names of all assigned IO devices” as shown below :






www.molex.com 8

Once done, you need to go to the topology view. Double click on “Devices & networks” and then open

the “Topology view”. (See below)








Note! In case of using a PROFINET Switch physically between the Molex IO module and Siemens CPU, you will need to add the GSDML of this switch in the device library (only if it does not exist in the list). Then add the Switch in the hardware configuration and then go back to topology view to link the Ethernet ports of the Molex module and CPU to the switch the same way it’s physically connected.

2. Media Redundancy Protocol (MRP) a. Using Step7 V5.x / TIA portal V1x ( with no PROFINET switch)

Pre-requirement 1: S7 CPUs supporting MRP feature.

Pre-requirement 2: Molex Product Version (minimum): TCDEP-8xxP-DxU-G (PV 2.1.3.0) / TCDEP-

8XXY-DxU-01 (PV 2.1.7.0) / TCIEP-888P-D1U (PV 1.0.0.0)

(available from Molex IO block web server (PV 2.1.7.0) or from our Download Center.)

Firstly, the S7 PLC will be the MRP manager. See below the configuration of the PLC as manager.

Step7 V5.x

TIA portal V1x






www.molex.com 10

The first and second Molex IO devices “harshio600-epn” and “harshio600-epn-1” must be configured as

client. See below

TIA Portal V1x

Note! Link all the devices in a ring topology. It must match the real physical network topology.

Once the configuration is downloaded to the PLC, there is nothing else to do.

b. Using TIA portal V1x ( with PROFINET switch)

Pre-requirement 1: S7 CPUs supporting MRP feature.


8XXY-DxU-01 (PV 2.1.7.0) / TCIEP-888P-D1U (PV 1.0.0.0)

(available from Molex IO block web server (PV 2.1.7.0) or from our Download Center.)

Pre-requirement 4: PROFINET switch supporting MRP feature (ex: Siemens Scalance)

The S7 PLC will NOT be the MRP manager. So, it will be configured as “not device in the ring”. See

below the configuration of the PLC






www.molex.com 14

The PROFINET switch will be configured as IO device. It will be the manager of the MRP network.

Firstly link the devices in the topology view before configuring the MRP roles. The tool TIA portal will

assign automatically the MRP ports once the roles are defined.

The network topology will be as follows.

Note! Link all the devices in a ring topology. It must match the real physical network topology.

The PROFINET switch must be configured as MRP manager.
