Operating instructions – AC SMART
Connection via Modbus TCP (LAN)
The EV charging boxes in the AC SMART product family can be connected
to an external device via interfaces X2 or X3. Upon delivery, the Modbus TCP
interface is configured as follows:
Ethernet interface
100Base-TX according to IEEE 802.3u /
10Base-T according to IEEE 802.3
Connection type
RJ45 socket /Ethernet
Protocol
Modbus TCP
Transfer rate
10/100 Mbit/s
Max. cable length
100 m
Recommended cable
CAT-6
DHCP is deactivated upon delivery. The charging controller is accessible as
follows.
IP address
192.168.0.8
Port
502
Address
255
Also observe the Modbus register. The tables are available on the Weidmüller
website.
Connection via Modbus TCP (WLAN)
To use the Modbus TCP interface via WLAN, the EV charging box must be
connected to a WLAN network, see Chapter 9.3

Connection via Modbus RTU
The EV charging boxes in the AC SMART product family can be connected
via interfaces X5.1 and X5.2 on the control board in the housing cover in a
Modbus RTU network (RS485). Upon delivery, the Modbus RTU interface is
configured as follows:
Address
100
Speed
19200
Parity
None
In the VALUE and ADVANCED product lines, the RTU interface has a switch-
able terminating resistor. The terminating resistor is activated as a default.
►
Connect the external device to the Modbus RTU interface (X5.1 and X5.2)
of the control board in the housing cover
►
Start the web server, see Chapter 9.3.
