Controllers and Software

High-side output for positive signal. UB

UB Last / load
Dialogue modules

Low-side output for negative signal.

Further important functions: Gateway functions All controllers have at least one CAN interface which is used to transfer data, e.g. to the decentralised input / output modules or to a dialogue module through the CANopen protocol. The CANopen protocol enables fast and flexible connection to the bus. Controllers with more than one CAN interface can be used as gateway. Two different CAN networks can be easily connected to each other. They enable direct processing of for example control and diagnostic data of Diesel engines with SAE J 1939 protocol. As an alternative the second CAN interface can also be used for freely definable CAN messages (CAN layer 2). For the SmartController CR2501 the second interface is designed as “truck-trailer interface” to ISO 11992. Programmable to IEC 61131-3 Programming via CoDeSys with the programming languages from the standard IEC 61131-3 enables the user to create clear and easy application software. Function libraries are available for the special hardware functions (e.g. gateway SAE J 1939 / CANopen).

Here triggering of the proportional Hydraulic functions is performed by current-controlled PWM outputs.

Mobile controllers

Digital and PWM outputs For the controller outputs three types can be differentiated: High-side digital outputs with or without diagnostic function High-side digital outputs with or without diagnostic function and additional PWM mode PWM outputs with or without current control function Current-controlled PWM outputs are mainly used to trigger proportional hydraulic functions. The Classic and ExtendedControllers also enable selection of high and lowside outputs. This allows the implementation of H bridges, e.g. to trigger directional electric Motors, in these devices.
