To enter an IP configuration manually, a valid available IP address on the network must
be known. Contact your network administrator to obtain the parameters for manual IP
configuration.
NOTICE!
In the Versatronic, the TCP port 502 is set permanently to Modbus/TCP
and cannot be changed.
With Modbus/TCP, it is not necessary to configure the Modbus device
address. Bus users are identified by their IP addresses. The Unit ID
(Modbus device address in the Modbus/TCP telegram) is set permanently
to 255 in the Versatronic (
Each host on a network must have a unique IP address. If an IP address
exists several times on the network, an address conflict will result. It must
be ensured that fixed IP addresses lie outside the DHCP IP address range
and are assigned only once.
The transmission times in an Ethernet network depend on the network
structure and the traffic, among other things. As a result, delays in updating
the process values may occur when using Modbus/TCP.

Description
Manually: If no DHCP server is installed on the network
and the IP address configuration is known (e.g. by the
network administrator), the data are entered manually.
Manually
Automatically: A DHCP server is installed on the network.
Automatically
After being switched on and booted the Versatronic
receives the IP configuration from the DHCP server; IP
configuration takes place automatically.
