Each device on the Modbus RTU network, including the Master and Slaves, is assigned a unique ID for identification. The ID is used by the Master to address a specific Slave when sending requests or commands. The Slave devices should be configured with unique IDs to ensure proper communication.
The ID range for Modbus RTU devices is from 1 to 247. ID 0 is reserved for broadcast messages, where the Master can send a message to all Slaves simultaneously. The ID assignment is typically done during the configuration of the devices, and it's important to ensure that there are no duplicate IDs within the network.
It's worth noting that Modbus RTU supports both 2-wire and 4-wire RS-485 connections. The wiring details for RS-485 depend on the specific implementation and hardware being used. Typically, twisted pair cables are used for communication, with one wire for data transmission (A or positive) and another for data reception (B or negative). The wiring should be consistent across all devices in the network to establish proper communication. Additionally, proper termination resistors may be required at the ends of the RS-485 network to minimize signal reflections and ensure reliable data transmission.
Device Connections: Multiple devices can be connected in a daisy-chain configuration. Each device has its own unique Modbus address. The A and B lines of one device are connected to the corresponding lines of the next device, forming a chain.
Twisted Pair Wiring: Two wires are used for communication: one for transmitting data (A or "+" line) and one for receiving data (B or "-" line). These wires are typically twisted together to minimize interference.
Grounding: It is essential to establish a common ground between all devices to ensure proper signal integrity. Connect the ground terminals of all devices together.
