There are no obligatory Modbus/TCP driver
config entries that have to be set in the configuration file.
The in the past obligatory config entry plc
is obsolete since WinCC OA
version 3.9.
The specification of a server port is only
required, when the default port number 502 should not be used,
for example:
[mod_2]
tcpServerPort = 502
 Caution
If several drivers are started on one computer
different server port numbers have to be configured for these
drivers. For this reason change on the PLCs the port numbers the
drivers use so that you can connect to the driver. |
