About This Application

This Tibbo BASIC app allows you to set up and test Tibbo Bus Probes, also known as "RS485 Modbus Sensors." Users interact with the app through the LCD and keypad of the TPS2L(G2) device (there is also a BP-Tester-Web app that implements a web interface).

Using this app you can :

  • Set up the Bus Probes:
    • Upload Monitor/Loader Firmware;
    • Upload Application Firmware;
    • Set Modbus IDs.
  • Monitor the Bus Probes:
    • Scan for connected Probes (discover Modbus IDs of connected Probes);
    • View firmware versions of discovered Probes;
    • View readings of discovered Probes.

Required Hardware

Run this application on the following TPS configuration: TPS2LG2_BP-Tester-UI.

Bus Probes are connected as shown in the diagram.

Testing Notes

For the most part, the app is self-explanatory. Here are a few notes you may find useful:

  • You must scan for connected Probes (discover them) before you can view firmware versions or readings of these Probes.
  • If you have but a single Probe connected, you do not need to bother with setting a Modbus ID of your Probe.
  • If you have more than one Probe connected, you must make sure that each Probe has a unique ID. You can verify this by connecting one Probe at a time and then scanning for connected Probes.
  • Setting a Modbus ID of a Probe requires the MD button of the Probe to be pressed while the ID-setting Modbus command is being executed. A Bus Probe would reject the ID change request if it was received while the MD button wasn't pressed.
  • Unless a new app version containing updated firmware has been released, there is no need to upload the Monitor/Loader or the application firmware into the Probes.
  • When updating Probe firmware, only connect a single Probe to the RS485 port of your TPS2 device.
  • If you have connected a large number of Probes and their info does not fit on a single page (LCD screen), use the MD button to flip through pages.
