Detailed Answer
RS485 and CAN are both industrial field buses: RS485 uses differential signals, is simple and cheap, and is half-duplex; CAN supports multi-master communication with strong real-time performance and good anti-interference. The receiver of an industrial remote control can communicate with PLCs and host computers via RS485/CAN for remote monitoring and parameter configuration. The LDER LD series offers optional RS485 output, and XINGJIA offers an optional CAN bus. For enterprises needing networked equipment monitoring, choosing bus-capable models is a wise move.
| RS485 | Differential / cheap |
| CAN | Real-time / anti-interference |
| Application | Networked monitoring |
Note:If you have networking needs, add the bus interface to reserve expansion capability.
