UDP interface: Guidelines
The following section contains rules and guidelines to ensure the best
usability.
2.1
Required command delays
The following time intervals are the minimum required waiting times between
UDP commands in general and the scheduled repetition of the same
command. Any application communicating with xChargeIn is required to
comply with these waiting times.
The minimum waiting time between any two UDP commands is defined as
follows:
● t_UDP_pause = 100 ms
The minimum waiting time between the scheduled repetitions of any UPD
command is defined as follows:
● t_COM_pause = 5 s
The minimum waiting time after sending a disable command (e.g.
ena 0
) is
defined as follows:
● t_DIS_pause = 2 s
2.2
Addressing and communication port
Always use direct addressing for communication. This means that each
command or UDP session has to contain the IP address of the specific
charging station.
The port used for UDP communication is 7090. Ensure that this port is not
blocked by a firewall or other ongoing communication.
Information
Do not communicate with a charging station without addressing it by its IP
address. Even if it seems to work fine in some cases, this practice is
dangerous for multiple stations in the same network. This feature will be
discontinued.
