Changing the IP addressdl-permalink__symbolPermalink

  1. In order to change the IP address of devices perform a network scan.

    ⮫ “Network scan”

  2. Select a device from the list and select the appropriate protocol under “Scan protocol”.

    “DHCP” or “BOOTP” option: If required, DHCP or BOOTP can be used to receive the IP address for the device from the server.

    “IP address”, “subnet mask”, “Std. gateway”: Use these fields to change the IP address settings including the settings for the subnet mask and the standard gateway. Ensure that the combination of connection settings is correct.

    Note for CI52x-Modbus devices

    Note for CI52x-Modbus devices

    Consider the behavior of CI52x-Modbus devices if the last number of the IP address is set to "0".

    ⮫ “Check last number of IP address”

  3. Set the PLC to “Stop” (otherwise the change is not accepted).

    Note for configurations with several configurable Ethernet ports (ETHx) e.g. PM5630-2ETH and CM5640-2ETH

    Note for configurations with several configurable Ethernet ports (ETHx) e.g. PM5630-2ETH and CM5640-2ETH

    All interfaces (ETHx) of the PLC onboard and CM5640-2ETH modules need configuration to be in different subnets. Overlapping of subnets must be avoided.

    ⮫ “Switch functionality of Ethernet interfaces ETH1/ETH2”

  4. Change the settings for the IP configuration and click [Send settings] to transmit the data to the device.

    Note for PROFINET devices

    Note for PROFINET devices

    The device name of PROFINET devices can be edited. If changing the name, ensure the following rules apply:

    • Labels must be separated by "."

    • Total length: 1 to 240

    • Label length: 1 to 63

    • Labels can consist of characters [a-z] and numbers [0-9]

    • Labels are not allowed to start with "-"

    • Labels are not allowed to end with "-"

  5. In order to keep all IP changes after a power cycle, the settings can be stored permanently. Confirm the prompted message during the scan process.

Check last number of IP address

This hint is only valid for CI52x-Modbus devices.

Check the last number of the IP address. If it is set to "0", the IP address setting for this last number will be used from the rotary switches on the hardware device.

Example:

Automation Builder

AC500 communication interface module (rotary switch)

IP address:

192.168.14.0

IP address:

6
IP_Address_1 Rotary_Switch

As a result, in the field “IP Address” the last number is set to "6":

IP_Address_2
