What's Needed

Please refer to the other Appplication Notes under the "Applications" menu for more specific details on the hardware and available software.

Step 1 - Backplane Configuration

1.1 The backplane configuration applies for both the VPE-6000-N basic version and the VPE-6000-E Enclosed version.
1.2 The backplane ID is determind by the jumpers located on the rear skirt of the board betweeen the black terminal blocks.
1.3 There are four jumper locations labelled "8", "16", "32" and "64".
1.4 Each Backplane comes with an "Accessories" bag containing 4 jumpers and 1 CAN bus termination resistor
1.5 Determine the required backplane ID for the user application, and install the appropriate jumpers 1.6 Default backplane ID is "0", no jumpers installed, for single backplane applications

Step 2 - Power Supply Configuration

2.1 If the user application will be supplying 5 VDC through a remote power supply, ensure the power supply can supply a clean 4 A @ 5.1 VDC, the preferred voltage for a Raspberry Pi 4 application.
2.2 If the user application will only be supplying the field voltage (typically 24 VDC), ensure the 24 VDC can provide minimum 2 A plus the remote I/O device power requirements.
2.3 When using the VPE-6010 Power Supply, the on board default jumpers are installed as follows:

Step 3 - Inserting Modules

3.1 Any Module can be inserted into any backplane slot position
3.2 Each module position has card guide slots tp prevent module from being inserted incorreclty
3.3 The module NodeID is the "Backplane ID" determined by the backplane jumpers and the addition of the slot in which the power supply is plugged into.
Example 1: If the backplane has no jumpers and the power supply module is plugged into slot position 0, the NodeID is 0 + 0 = 0.
Example 2: If the backplane has a jumper in the "8" position and the power supply is plugged into slot postion 2, the NodeID is 8 + 2 = 10.

Step 5 - Network Configuration

5.1 The WL-MIO system allows for up to 16 backplanes
5.2 Ensure each backplane has a unique ID via the jumper installation

Step 6 - Loading Control Program

6.1 Ensure the "libwlmio" is installed on the SD card for the processor (loaded by default if the processor is supplied by Widgetlords)
6.2 If required, download the "libwlmio" library from our GitHub site
6.3 Refer to the "Applications" menu for application notes on software demo programs
