modbus_tcp/config

Modbus/TCP server configuration

Example

HTTP (curl)

# $HOST e.g. warp-AbCd

Read

curl http://$HOST/modbus_tcp/config

{ "enable": true, "port": 502, "table": 0 }

Write

curl http://$HOST/modbus_tcp/config -d '{ "enable": true, "port": 502, "table": 0 }'

MQTT (mosquitto)

# $BROKER e.g. my_mosquitto.localdomain
# $PREFIX e.g. warp/AbCd

Read

mosquitto_sub -v -C 1 -h $BROKER -t $PREFIX/modbus_tcp/config

{ "enable": true, "port": 502, "table": 0 }

Write

With MQTT on $PREFIX/modbus_tcp/config_update

mosquitto_pub -h $BROKER -t $PREFIX/modbus_tcp/config_update -m '{ "enable": true, "port": 502, "table": 0 }'

Name	Description
enable bool	Indicates whether the Modbus/TCP server is active. For control functionality in addition to state readout, evse/modbus_tcp_enabled must also be true.
port int	Port on which the Modbus/TCP server listens for incoming connections. Typically 502.
table int	Register table used by the Modbus/TCP server. 0 - WARP Charger register table 1 - Register table compatible with Bender CC612/613 2 - Register table compatible with Keba C-Series
send_illegal_data_address bool	Indicates whether the Modbus/TCP server sends IllegalDataAddress errors when unknown registers are read true - The server responds with an IllegalDataAddress error when an unknown register is read. false - The server responds with value 0 when an unknown register is read.
