In the form of the PLCcore-iMX35 CODESYS a powerful Soft-PLC is available as basis for user-specific HMI-devices. The PLC Runtime System is CODESYS V3. The minimal necessary peripheral connectivity of the core module simplifies the design of application-specific baseboards. Due to the various local in- and outputs as well as the on-board supported communication interfaces, the PLCcore-iMX35 can be connected to its peripheral environment by several network interfaces in versatile manner. Additional fields of application are given by the possibility to allow for execution of separate Linux applications in parallel to the PLC Runtime System.

Making PLC available as an insert-ready core module with small dimensions reduces effort and costs significantly for the development of user-specific controls. The PLCcore-iMX35 CODESYS is also very well suitable as basic component for custom specific HMI devices as well as intelligent network node for decentralized processing of process signals (CANopen and UDP).

The PLCcore-iMX35 CODESYS is an IEC 61131-3-programmable Soft-PLC with integrated target visualization. That's why it represents itself as the ideal base component for designing user specific HMI devices. The PLCcore-iMX35 CODESYS provides 16 digital inputs and 10 digital outputs for direct connection to local peripherals. Due to the various communication interfaces such as Ethernet, CAN and serial interfaces, furthermore remote extension equipment can be connected. The PLC Runtime System supports data exchange by several CODESYS libraries for CANopen, CAN Layer 2 and serial COM interfaces.

The PLCcore-iMX35 CODESYS allows for direct connection of CMOS and LVDS displays. The integrated target visualization is based on the CODESYS-internal Visualization Manager, which uses Qt components. It supports a touchscreen, a USB mouse as well a USB keyboard as input devices. The necessary Qt components for the visualization are provided by the Linux BSP and are available to the PLC Runtime System. A separate installation of the Qt components as handled in former systems (e.g. PLCcore-9263 CODESYS) is no longer necessary.

Only a minimal peripheral wiring is necessary to apply the PLCcore-iMX35 CODESYS on an application-specific baseboard. That's why devices based on this core module can be designed very cost-efficiently.

Additional arbitrary Linux applications can be executed on the PLCcore-iMX35 CODESYS in parallel to the PLC Runtime System. For data exchange between a Linux application and the PLC Runtime System, inter process communication mechanisms such as FIFOs or Shared Memory are available. Furthermore, the PLC has full access to the file system. On demand, data can be written to or read from any mounted media.

The PLCcore-iMX35 CODESYS is equipped with an on-board Flash of 128 MiB, whereby a memory range of 90 MiB is freely available as mass storage for the PLC program, for visualization data and for process data. Due to the usage of UBIFS (Unsorted Block Image File System) with active journaling, the file system keeps in a consistent state even in case of an unexpected power supply crash.

The PLC Runtime System allows for usage of one CAN interface as CANopen-Manager. A CAN Layer 2 communication can be performed over both CAN interfaces. The therefor necessary function blocks and functions are implemented in the CODESYS-internal libraries. The integrated CAN controllers are equipped with a receive FIFO. That's why even applications with permanent CAN bus load up to 70 percent can be implemented without any packet loss of CAN messages.
