Filename: PAC-INT-CAN-RXTX-R1.0b.zip
File Size: 154 KB
Last Update: 6/24/2015
Compatibility: Windows 7 Professional (64-bit), Windows 7 Professional (32-bit), Windows Vista Business (32-bit), Windows XP Professional (32-bit SP2), Windows 8.1 Professional (32-bit), Windows 8.1 Professional (64-bit), Windows 10 Professional (32-bit), Windows 10 Professional (64-bit)


The Opto 22 CAN Integration Kit for PAC Project - Transmit and Receive provides sample PAC Control subroutines and charts so that your Opto 22 SNAP PAC System equipped with one or more SNAP-SCM-CAN2B modules can communicate with devices on a Controller Area Network (CAN).

The sample subroutines in the integration kit run as part of the PAC Control strategy on an Opto 22 SNAP PAC controller. They show you the PAC Control commands to use for CAN communication and the format of data in them. The charts illustrate how to call the subroutines. You can add to or modify the subroutines and charts to match your system.

This integration kit is documented in form 2151, the CAN RX/TX Integration Kit for PAC Project Technical Note.


This integration kit requires SNAP-SCM-CAN2B modules with firmware R2.0b or higher. With this firmware the module can both send and receive CAN data; with earlier firmware the module only receives data. You can update an existing module to the new firmware following steps in the PAC Manager User’s Guide.

For modules with firmware R1.0d and lower that only receive data, use a different integration kit (part number PAC-INT-CAN-RX).
