What are the advantages of PLC with CAN port communication?
Nowadays, most of the PLC interfaces are serial ports and Ethernet ports. Since CAN has only appeared in recent years, it is said that there are very few CAN interfaces in current PLC. Although CAN interface is not very popular, PLC with CAN interface has the following advantages compared with common ordinary PLC:
1. The instantaneousness of bus communication is stronger, and the system delay is reduced. Industrial communication attaches great importance to the dimension of latency. CAN bus is first-class in this respect, far stronger than Ethernet.
2. The CAN bus uses differential voltage signals to transmit data, with its own CRC error detection mechanism, which can be used normally in complex interference environments.
3. The use cost of CAN bus is very low, which is convenient for secondary development.
Through the above comparison, we know why PLC use CAN communication is very advantageous. So what is the PLC with CAN interface like? Let me introduce to you the following GCAN-PLC developed and produced by GCAN
●With CAN interface, Ethernet port, serial port and other communication interfaces
●Pluggable chip expansion IO module, maximum 256 channels of IO points can be expanded, optional IO types include: analog, digital, counter, PT100, etc.
●Using German embedded real-time (run-time) kernel system, with strong real-time and processing capabilities, and the system also supports five programming languages
●Support 4G, WIFI, GPRS, Bluetooth and other special communication port expansion, support customized production on demand
Guangcheng Technology GCAN-PLC is a modular and arbitrarily expandable PLC controller. The I/O points are connected to the main communication module by means of inserts, and the I/O points can be arbitrarily expanded according to actual needs. The equipment adopts The German core has more stable performance. In addition to the traditional PLC's network port and serial port, it also has a CAN bus communication interface. You can use these communication buses to connect to the corresponding network to communicate with other devices, and easily connect it to the communication control network. The compact appearance structure and flexible programmable function make this PLC can be used in almost any industrial field control and acquisition system, providing a very effective and economical solution for automation control.
