IPConfig Parameters

IP address configuration field on the IPConfig tab:

Parameter

Default Value

Description

Main IP address

192.168.10.1

The IP address of the controller and DIO scanner. This address can be used:

  • By Control Expert, an HMI, or SCADA to communicate with the controller.

  • To access the controller web pages.

  • By the controller to perform I/O scanning of DIO devices.

IP address A

192.168.11.1

This address applies to the RIO scanner service in the controller designated as A. (See the note below.)

IP address B

–

For M580 Hot Standby controllers only, this address applies to the RIO scanner service in the controller designated as B. (See the note below.)

Subnetwork mask

255.255.0.0

This bit mask identifies or determines the IP address bits that correspond to the network address and the subnetwork portion of the address. (The value can be changed to any valid value in the subnetwork.)

Gateway address

192.168.10.1

This is the IP address of the default gateway to which messages for other networks are transmitted.
NOTE:

  • If you change IP address A , the system may recalculate all IP addresses (including those of the drops) to keep all devices in the same subnetwork.

  • In M580 Hot Standby systems, both controller A and controller B maintain a redundant owner connection with each RIO device (BM•CRA312•0 adapter). For this reason, when a Hot Standby switchover occurs, the state of RIO outputs is not affected – the Hot Standby switchover transition is transparent.

Viewing and Editing the IP Address and Device Name of Network Devices

The CRA IP address configuration area on the IPConfig tab is provided for controllers with Ethernet I/O scanner service (controllers with commercial references that end 40). Use this area to display a list of RIO/DIO scanners and BM•CRA312•0 adapters, and view or edit the device IP address and device Identifier:

Step

Action

1

Click the CRA IP address configuration link to open the Ethernet Network window.

2

In the Subtype header, filter the device list by selecting:

  • Scanner RIO/DIO

  • CRA

  • ... (select both)

This list applies the selected filter, and displays all detected network devices of the selected type(s).

3

The IP Address field displays the address that was automatically assigned when the device was added to the network.

NOTE: Although the IP address is editable, accept the automatically assigned IP address.

4

The Identifier field displays the identifier for the module, which is also the Device Name . To edit the Identifier setting:

  1. Double-click on the Identifier value. The value becomes editable.

  2. Type in a new value.

  3. Click the Control Expert Validate button.

The new Identifier setting is applied.
NOTE: The other fields in the Ethernet Network window are read-only.

Advanced Configuration

To configure DHCP and FDR services in the DTM browser, click the Services configuration link in the Advanced configuration section of the window.
