== EMS CONFIGURATION ==
This section provides an overview of the Modbus RTU and TCP interface supported by EVC2.

The document provides description of the available Modbus registers for the external control and communication with the charge. This functionality is only available when the charger is configured as a secondary (server) device and waits for acceptable commands from the primary (client) device.

Interface allows EVC2 to be controlled via another device over the registers. For example a server might be calculating current electricity price and in so can be limiting or increasing the charging rate of the EVC2 dynamically by modifying its settings on the fly via the provided commands.

=== Device preparation for Modbus RTU ===
EVC2 must be configured as a secondary device via our mobile application and device must have RS485 wired connection with the primary device..

# Open "User menu"
# Open "Installer menu"
# Open "Load Management"
# Select "Modbus RTU"
# Select "Secondary"
# Enable secondary device

Check if the address is expected in your system

Connection terminals are marked as '''LM'''

[[File:EVC2_external_controller.png|frameless|460x460px]]

=== Device preparation for Modbus TCP ===
EVC2 must be configured as a secondary device via our mobile application and device must have a connection to the same network as its management system

# Open "User menu"
# Open "Installer menu"
# Open "Load Management"
# Select "Modbus TCP"
# Select "Secondary"
# Enable secondary device
