PZ96L-E4/H系列-测试电力参数方法 Types of digital communication: RS485 communication connection MODBUS/RTU communication protocol
Provide serial asynchronous half-work RS458 communication interface, using MOD-BUS-RTU protocol, all kinds of data information can be transmitted on the communication line. Up to 32 network power meters can be connected on one line at the same time. Each network power meter can set its communication address (Address No.). The communication terminal numbers of different series of meters are different. The communication connection should use copper The shielded twisted pair of the net, the wire diameter is not less than 0.5mm. When wiring, you should use communication cables away from strong electric cables or other strong electric fields. It is recommended to use a network connection method, and it is not recommended to use star or other connection methods.
MODBUS protocol adopts the communication connection mode of master-slave response mode on a communication line. First, the signal of the host computer is addressed to a terminal device (slave) with only the address, and then the response signal sent by the terminal device is transmitted to the host in the opposite direction, that is; a signal on a separate communication line All communication data streams are transmitted in two opposite directions (half-duplex working mode).
MODBUS protocol only allows communication between the host (PC, PLC, etc.) and the terminal device, but does not allow data exchange between independent terminal devices, so that each terminal device will not occupy the communication line when they are initialized, and the response arrives The query signal of this machine.
