SNAP-SCM-CAN2B

Production Specification

The SNAP-SCM-CAN2B serial communication module provides one channel for transmitting and receiving data from devices on a Controller Area Network (CAN).

The SNAP-SCM-CAN2B module is designed for use with Opto 22 ’s SNAP PAC R-series controllers and SNAP PAC EB-series brains, both the standard wired models and the Wired+Wireless™ models. The brain or controller processes the data from the module and can communicate the data to other parts of an Opto 22 SNAP PAC System or to another system (such as a Modbus® system or an OPC client).

The SNAP-SCM-CAN2B requires PAC Project version R9.2a or newer, and the R-series controller or EB-series brain used with the module must have firmware version R9.2a or newer. This module does not work with legacy brains or controllers.

The SNAP-SCM-CAN2B mounts on a SNAP PAC rack alongside other SNAP I/O modules (analog, digital, and serial) to provide the mix of signals needed at any location.

Opto 22's CAN Integration Kit for PAC Project - Transmit and Receive (part number PAC-INT-CAN-RXTX) provides sample PAC Control subroutines and flowcharts to help you configure your module and exchange data. You can modify the subroutines and charts as necessary for your application. To use the integration kit, see form 2151, the CAN RX/TX Integration Kit for PAC Project Technical Note.

IMPORTANT: This module includes both transmit and receive capability beginning with module firmware R2.0b. Modules with firmware R1.0d and lower can only receive data; these modules use a different integration kit (PAC-INT-CAN-RX).

To add transmit capability to an existing module, download the newer firmware and then follow steps in the PAC Manager User's Guide (form 1704) to update the firmware.

SNAP-SCM-CAN2B Communication Module Data Sheet

The SNAP-SCM-CAN2B serial communications module provides one channel for transmitting data to or receiving data from devices on a Controller Area Network (CAN).

The SNAP-SCM-CAN2B module is designed for use with Opto 22’s SNAP PAC R-series controllers and SNAP PAC EB-series brains. The brain or controller processes the data from the module and can communicate the data to other parts of an Opto 22 SNAP PAC System™ or to another system (such as a Modbus® system or an OPC client).

SNAP Serial Communication Modules User's Guide

The SNAP-SCM-232, SNAP-SCM-485-422, SNAP-SCM-PROFI, SNAP-SCM-W2, SNAP-SCM-CAN2B, and SNAP-SCM-ST2 serial communication modules are designed for use with the SNAP PAC System and can also be used in standalone I/O units. Each of these modules conveniently provides serial data at a remote Ethernet location.

  • - The SNAP-SCM-232 and SNAP-SCM-485-422 typically interface with printers, scales, chart recorders, and barcode systems.
  • - The SNAP-SCM-PROFI provides a standard electrical interface with PROFIBUS DP® networks.
  • - The SNAP-SCM-CAN2B provides an interface to a Controller Area Network (CAN), so your SNAP PAC system can receive data from CANbus devices.
  • - The SNAP-SCM-ST2 provides pulse and direction signals for stepper motor drives.
  • - The SNAP-SCM-W2 complies with the Wiegand interface format and is used for access control applications.

snap-scm-can2-R2.0b.eio

This firmware adds transmit capability to a SNAP-SCM-CAN2B serial communication module, which communicates with devices on a Controller Area Network (CAN). (A SNAP-SCM-CAN2B module with firmware R1.0d or lower can receive data but not transmit.)

See the Opto 22 CAN Integration Kit for PAC Project - Transmit and Receive (part number PAC-INT-CAN-RXTX) for helpful sample PAC Control subroutines and charts to help you integrate devices on a CAN network with your Opto 22 SNAP PAC controller.

To update firmware on an existing SNAP-SCM-CAN2B module, follow steps in Form 1704, PAC Manager User's Guide.
