Frequency converters are sometimes mounted at places, in which they have the most processing power of the surrounding devices. Often the remote monitoring of frequency converters has been implemented in an external programmable logic controller PC which is connected to the Internet. Sometimes it is not reasonable to use an extra computer at the location, which means the remote connection should be directly connectible to the frequency converter. This master’s thesis studies the possibility to use SOAP for a remote connection, established from the frequency converter to an external database server. The objective is to create a remote monitoring connection which is easily deployable for the end user. The implementation considers compatibility issues with firewalls, proxy servers and NAT routers.
