Protocols

Automatic detection of the protocol

On delivery, the network module is in autodetect mode. This mode actively monitors the network to identify the bus type used. A green running light on the IO-Link ports indicates the active detection process.

As soon as the module has successfully identified the network type, the corresponding port LEDs quickly light up green. The assignment of the LEDs to the various fieldbus protocols can be found in LED assignment to fieldbus protocols. After successful detection, the device restarts automatically and can then be accessed via the detected fieldbus protocol.

To put the module back into autodetect mode, either the display (see chapter Select protocol in the display) or the WebUI (see Change protocol) can be used.

In autodetect mode, the device can be reached at any time via the IP address 192.168.1.1 with subnet mask 255.255.255.0.

Manually select protocol

For devices with a display, the protocol is selected manually via the integrated display (see chapter Select protocol in the display).

The table below shows other options for manually selecting the protocol for devices without a display.

From Autodetect

To switch from Autodetect (ATD) to PNT, EIP, ECT, MBT, use the following options:

• Automatic detection
  OR

• Set manually via:

  • IP assignment via WebUI

  • Changeover via WebUI (see Change protocol)

From PNT

To switch from Profinet (PNT) to ATD, EIP, ECT, MBT, use the following options:

• IP assignment via DCP (BET, Proneta)

• Changeover via WebUI (see Change protocol)

From EIP

To switch from EtherNet/IP (EIP) to ATD, PNT, ECT, MBT, use the following options:

• IP assignment per TCP/IP object or per WebUI (see Make network settings)

• Changeover via WebUI (see Change protocol)

From ECT

To switch from EtherCAT (ECT) to ATD, PNT, EIP, MBT, use the following options:

• Activate EoE (see EoE set-up)

• Changeover via WebUI (see Change protocol)

• Changeover via CoE (see Change protocol for set ECT)

From MBT

To switch from Modbus/TCP (MBT) to ATD, PNT, EIP, ECT, use the following options:

• IP assignment via WebUI (see Make network settings)

• Changeover via WebUI (see Change protocol)

WebUI default settings

The protocol can also be selected via the WebUI (see Change protocol). By default, the WebUI can be reached via the IP address 192.168.1.1.

If the protocol is changed, the IP parameters are reset to the default value of the respective protocol, as shown in the following table:

Change protocol for set ECT

Proceed as follows if ECT is already set and the protocol should be changed.

1. Select CoE object Fieldbus Information (0xF502).

   

2. Select and set the desired protocol in the object Protocol After Reboot.

   

Then the module must be restarted as follows:

1. Select CoE object Module Reboot (0xF503).

   

2. Set object Action to Reboot.

   

3. Set object Trigger to True.
