  • The installation and maintenance staff of a system with electric devices must be instructed by the manufacturer regarding potential dangers, required safety measures and applicable safety provisions before beginning work.

Product Description

  • The connected controllers by MRS Electronic are used for the expansion of existing CAN control but can also be used as independent PLC control units.
  • For controllers with HCS08 or HCS12 Processor (see datasheet): The software tool CANgraph and the suitable flash programming tool MRS Developers Studio or programming with a C-programming system are used for graphic programming.
  • For controllers with S32K Processor (see datasheet): You can program the controllers with our Applics Studio. With the graphical programming environment developed in-house and the improved programming options, it is now even easier to program your application. You can find the documentation online at: https://applics.dev/
