Multibus Module
The Multibus Module expands your GOcontroll Moduline controller with a rich set of communication interfaces. It adds multiple independent CAN FD and RS485 channels — plus a galvanically isolated module-to-module link — to bridge, gateway and route data between the networks in your machine.
Like every Moduline module, it plugs straight into a controller expansion slot and is programmed through the GOcontroll platform.
Applications
- Protocol gateways that bridge and translate data between CAN FD and RS485 networks
- Adding extra CAN FD bus capacity to complex machines and vehicles
- Coupling separate CAN FD subsystems or sub-networks to a single Moduline controller
- Connecting RS485-based field devices, sensors and actuators to a Moduline controller
- Interfacing RS485 serial field buses in industrial and mobile machinery
- Galvanically isolated communication between separated sub-systems or controllers
- Isolated battery-pack / BMS communication over the isoSPI link
- Linking two Moduline controllers across a ground-potential difference via isoSPI
Features
- 3× independent CAN FD interfaces
- 3× independent RS485 interfaces (individually switchable transceivers)
- Galvanically isolated isoSPI module-to-module link
- Voltage configurable auxiliary supply (5 to 20 V, 250 mA)
- Programmable with the GOcontroll-CodeBase (C)
Communication interfaces
3× CAN FD — three independent CAN FD controllers (each with standby control) connect the module to several vehicle and machine CAN networks at flexible data rates.
3× RS485 — three independent, individually switchable RS485 transceivers for half-duplex serial field buses, letting you tie in RS485-based devices and sensors.
Isolated isoSPI link — a galvanically isolated SPI channel lets two Multibus modules exchange data safely across a ground-potential difference, for example between separated sub-systems or controllers.
