ACHTUNG
8.5.2 Load Management via Modbus Interface
> The conguration and setup of a ModBus TCP (LAN) interface and the activation of the load
management of the charging power is done by EnerCharge during commissioning.
> The ECC 320 can be congured as ModBus Server or as ModBus Client.
> The ECC 320 must be connected to the customer server/client via LAN cable.
• If the ECC 320 is connected to the Internet via a SIM card, an additional LAN cable is required.
• In case of Internet connection via LAN cable, the existing line can be used for the ModBus LAN interface.
> Port 515 of the ModBus TCP connection is used for the connection.
> Die IP-Adresse entspricht jener des Routers (der ECC 320) im lokalen Netz des Betreibers.
> The register list (see Table 6 and Table 7) denes the data exchange.
The registers are dened as "holding registers".
> The operator sets the maximum charging power in register "200 (siehe Table 7):
• Example: 180 (column factor) = 180 kW maximum charging power.
> The operator denes the maximum charging power in the event of a system failure or network
problem in register "201" (see Table 7):
• Example: 100 (column factor) = 100 kW emergency power limitation.
> Registers "100" and "101" (see Table 6) dene the upper and lower limit of the adjustable power
limitation. If the value dened in register "200" (see Table 7) is not within these boundary values,
the value set in register "200" is ignored.
> In register "103" (see Table 6) the applied value of the emergency power limitation is returned
as a control.
