Industrial production Line based on RS232/485 Communication bus system There are many tools for switching between buses, CANBUS serial card is just one of them, but it is also the most common one. After all, most of the bus systems previously used in factories are basically RS232 or RS485, and we don’t deny there’s other types of control systems, but they are the dominate two.
Industrial production structure Diagram based on CAN bus Communication
As mentioned above, under the premise of current industrial production, the original RS232/485 bus should be replaced by a more advanced CAN bus, but the reality is that the one-time replacement is too expensive and delays the daily production. So we need to connect the CANBUS serial card tools to the original bus system, then they can also have the characteristics of the CAN bus system,such as longer data transmission distance, higher baud rate, and more connected node devices. At the same time, it can reduce the probability of system error.
GCAN-207 CAN BUS serial card
GCAN-207 CAN bus serial card is a general serial-CAN conversion module developed by GuangCheng Technology recently. Comparing to traditional conversion module, not only the CANCOM upgrades in hardware workmanship, but also uses on-line conversion technology, that can use software to configure its serial communication mode(232 or 485), without disassembling the device or jumping wire. Add “ Format conversion” mode in function, using CANCOM conversion module, PC,PLC or other serial networking devices can be easily connected to the CAN-BUS network, forming a field bus laboratory, industrial control, intelligent community, automotive electronic network and other CAN-BUS network data processing, data acquisition, Control node for data analysis. CAN BUS serial card is a powerful tool for product development and data analysis, and a reliable assistant for engineering applications, project debugging. GCAN-207 CAN BUS serial card tool has the following characteristics: (1) It can realize the two-way data communication between CAN-bus and RS-232/RS-485, which can transfer CAN-bus to RS232/485, and RS232/485 to CAN-bus.. (2) It supports CAN2.0A and CAN2.0B protocol, conforms to ISO/DIS11898 specification, receives and sends either standard frame data or extended frame data. (3) It provides three data conversion modes: transparent conversion, transparent band identity conversion, Modbus protocol conversion, and users can choose according to their own needs. (4) It can choose standard DIN guideway installation or simple fixed installation, it is very convenient to use. (5) It provides the user with three kinds of data conversion directions: bidirectional conversion, only CAN serial, only serial CAN, user can set up by themselves.
