groov serial communication module, 2 channels, CAN, channel-to-channel isolation

Production Specification

The GRV-CCANI-2 serial module provides two independent, isolated serial channels (ports) allowing the GRV-EPIC-PR1 to communicate through a Controller Area Network (CAN).

Part of the groov® EPIC system, the GRV-CCANI-2 mounts on any groov EPIC® chassis alongside a GRV-EPIC-PR1 processor and analog and discrete groov I/O modules, to provide the mix of signals you need at any location. 

groov serial modules are directly connected to the processor via the bus on the chassis, so each serial port works like a port that’s built into the processor. Serial modules can be placed in any of the first four positions on the chassis, and groov serial modules contain two to four channels, so depending on the serial communication modules you use, you can add 8 to 16 serial ports to your GRV-EPIC-PR1.

Note that this direct connection means that an EPIC processor can control serial modules on its own chassis, but it cannot control serial modules on a separate EPIC chassis. Other devices, such as a SNAP PAC controller, also cannot control serial modules on an EPIC chassis.

Important Notes:
  • This module requires groov EPIC Firmware 1.5.0 or higher on your GRV-EPIC-PR1.
  • It currently works only with CODESYS applications (with version of Opto 22 Library Package for CODESYS Development System) and custom control programs with shell access.
  • PAC Project support will be available in a future release.
