This Opto 22 CAN Integration Kit for PAC Project - Receive Only provides a sample PAC Control strategy to enable your Opto 22 SNAP PAC System equipped with one or more
snap-scm-can2b模块
receivedata from devices on a Controller Area Network (CAN network).
The sample strategy in the PAC-INT-CAN-RX integration kit runs on an Opto 22 SNAP PAC controller, and includes a variety of Parameter Group Numbers (PGNs) for use with J1939, NMEA 2000, ISO 11783, and other communication standards. Depending on your CAN’s implementation, you may be able to use the strategy as-is; if not, you can modify or add to it to work with your system.
样本策略包括：
- CAN_Comm chart, which receives data from one to four Opto 22 SNAP-SCM-CAN2B modules. The module can receive all CAN data or you can filter by PGN.
- Data_entract图表，将PGN数据转换为每个地址下每个PGN的变量。
- Get_CAN_Data subroutine, which you can add to your strategy.

重要的：如果您还需要
发送data, use the CAN Integration Kit for PAC Project - Transmit and Receive (part number
pac-int-can-rxtx) instead of this one. To both send and receive data, your SNAP-SCM-CAN2B serial module must have firmware 2.0b or higher. (You can upgrade firmware following steps in the PAC Manager User's Guide.)
