Controller pinning

Due to the architecture of the controller, several connector have a dynamic pinning since the pinning depends on the modules that are plugged in. The exact pinning from each connector is described in the datasheet from each module.

Fixed pinning connectors

Communication connectors

The Moduline is equipped with two M12 connectors for USB and Ethernet connection. The connectors have respectively a B and D code key to prevent connecting the communication buses the wrong way.

USB

Ethernet

Antenna connector

The Moduline III and IV standard provide WLAN and P2P (2.4ghz) wireless communication. An antenna (included) needs to be placed on the SMA connector of the enclosure

WLAN

GNNS

4G -LTE - NB-IoT

System connector

To power up, it is essential to supply the controller with the system connector (aka C-connector). Beside the supply pins, this connector also provides the onboard communicaion buses such as CAN (2x M-II & M-III, 4x M-IV) and LIN (only M-IV) and the activation pins (1x M-II & M-III, 3x M-IV).  The activation pins can wake-up the controller by switching this input to a high level. The voltage applied on these input pins can be read out in Node-RED or Matlab Simulink. For more information, check Control algorithm with Node-RED or Control algorithm with Matlab-Simulink.

Dynamic pinning connectors

Since the Moduline is a modular controller, the pins from connector A – B – D and E depends on the module that is plugged into a specific slot in the controller. The best way to describe the pinning is by providing an example.

Input Module

The picture below shows the connector pinning from the Input module. Be aware of the different pinouts when the module is plugged into even or odd module slots.

For example let’s assume an Input Module is plugged into expansion slot 5:

  • The corresponding connector is D
  • The 5V sensor supply pins are: 5-6-7
  • The sensor ground pins are: 24-25-26
  • The signal input pins are: 13-19-12-18-11-17

Output Module
