Modbus Interface – Cutsforth Support

To convert the alphanumeric brush location tags to a numeric value that corresponds to the Modbus outputs, use the following schema: From smallest to largest: 1A, 2A, 3A,…, 1B, 2B, 3B,…, 1C, 2C, 3C, etc.

Note

The Brush Condition Monitoring System should be configured as a slave device.

Refer to this table when programming the Modbus output on your Brush Condition Monitoring System:

Entering a Static IP Address

Plug the USB keyboard into the BCM system.
Press Alt+F2 to pull up the Application Finder.
Click on the green arrow that is pointed down to display the window of options.
Scroll down, select Network Connections, and click Launch.
Double-click Wired Connection 1.
Select the IPv4 Settings tab.
Under the Method drop-down, select Manual to change IP configuration settings to static.
Click Add.
Enter the desired addressing information, and click Save when you are finished.

Locating the MAC Addresses

Connect a USB keyboard to the BCM system.
From the BCM Application Home Screen, press CONFIG in the upper-right corner.
At the bottom of the Configuration screen, press Advanced Configuration. When prompted, enter the administrative password.
In the lower-right corner of the Advanced Configuration screen, press Set System Time.
From the Data & Time screen, press the back button in the upper-left corner.
From the All Settings menu, select Network.
The MAC addresses will be listed as “Hardware Address” under each “Ethernet” option in the list on the left hand side.
