1. Comes with common communication interfaces such as CAN interface, Ethernet port, RS232/485, etc.
Users can program it arbitrarily to achieve bus communication and networking, and support common communication protocols such as: CANopen, ModbusRTU, ModbusTCP, etc.
2. Using 10 plug-in expansion methods, the number of I0 can be flexibly expanded at will
The GCAN-PLC series can expand the number of IO according to the actual needs of the user. The maximum scalability supports 256 IO points and the user can freely choose the type of IO such as: analog, digital, counter, PT100, etc. The GCAN-PLC series is very easy to expand. Users only need to insert the corresponding functional modules to achieve it. The module itself is very small in size. Users can expand rich functions in a compact space and flexibly respond to various industrial site needs.

3. Use five programming languages for flexible programming
The GCAN-PLC series uses the German embedded real-time (run-time) kernel system, which not only has strong real-time performance and processing capabilities, but the system also supports users to program it using 5 programming languages that comply with the IEC61131-3 standard, including : SFC (Sequential Function Chart), LD (Ladder Diagram), FBD (Function Block), ST (Structured Text), 1 L(Instruction List), flexible use of familiar programming languages can shorten the project development cycle.
GCAN-PLC can be programmed using 5 programming languages that comply with the IEC 61131-3 standard, including: SFC (Sequential Function Chart), LD (Ladder Diagram), FBD (Function Block), ST (Structured Text), IL (instruction list). A variety of standard programming languages can be used, making the PLC program highly portable and reusable. IEC 61131-3 also allows the use of multiple programming languages in the same PLC, allowing program developers to choose the most appropriate programming language for each specific task, and also allows different software modules in the same control program to use different programming language.
