Test App for Bus Probes

Release Date:	7-DEC-2018
Project files:	Open GitHub repository
Platforms:	TPP2W(G2)
Try it on:	TPS2(G2) device in the TPS2G2_BP-Tester-Web configuration

About This Application

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

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 Bus Probes (discover Modbus IDs of connected Probes)
  • View the firmware versions of discovered Bus Probes
  • Poll discovered Probes

Required Hardware

Run this application on the following TPS configuration: TPS2G2_BP-Tester-Web.

Bus Probes are connected as shown in the diagram.

Testing Notes

This app uses DHCP, so you will need to find out the IP address of your TPS before you can point your browser at it. The easiest way to do this is by using Tibbo's Device Explorer utility. You can install just Device Explorer, or our Tibbo IDE (TIDE) software — Device Explorer will be installed along with it.

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

• You must scan for connected Bus Probes (discover them) before you can view firmware versions or readings of these Probes.
• If you have only a single Bus Probe connected, you do not need to bother with setting the Modbus ID of your Bus Probe.
• If you have more than one Bus Probe connected, you must make sure that each Bus Probe has a unique ID. You can verify this by connecting one Bus Probe at a time and then scanning for connected Bus Probes.
• Setting the Modbus ID of a Bus Probe requires the MD button of the Bus Probe to be pressed while the ID-setting Modbus command is being executed. Bus Probes reject ID change requests received while the MD button isn'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 Bus Probes.
• When updating Bus Probe firmware, only connect a single Bus Probe to the RS485 port of your TPS2(G2) device.
