Overview of Modbus, RS485 and Ethernet
Properties
The charging station has two interfaces for networking
•
An RJ45 socket for Ethernet (cable type: CAT 6 or better). RJ45 copper Ethernet port. This
10/100BASE-T connection enables data rates of up to 100 Mbps and supports the Modbus
TCP/IP protocol. Standard UTP cables of Category 6 or better are recommended at an
industry-standard maximum distance of 100 meters.
•
An RS485 interface for Modbus RTU (cable type: Twisted Pair, shielded, 0.5 mm²)
You connect multiple VersiCharge devices via Modbus.
Note
Safety information
The ModBus protocol is an open protocol and it is the responsibility of the installer to ensure
the security of the wiring of these connections to prevent tampering.
Using the Modbus RTU protocol
VersiCharge charging stations can act as Modbus devices and make real-time data available
via the Modbus RTU protocol. Higher-level Modbus devices connected to the charger, e.g.
Modbus servers, can:
•
Read data
•
Write data to the registers of your charger
•
Make changes to the device configuration
•
Initiate control actions
This allows them to:
•
Take on the function of Child Modbus devices
•
Provide data in real time via Modbus protocol
Parent Modbus devices have the following tasks:
•
Read-only access to this data
•
Write data to the registers of your meter
•
Make changes to the device configuration
•
Initiate control actions
Modbus map
The Modbus map is available on request.
