HMI start-up

The exchange of data via the modem, SRIO etc., is much slower
than when directly connected to the front of the device. To avoid
having to read all the device data every time the HMI is started,
a file called ReXX.dat is created and a reference written in the
device every time device data are changed and saved. XX is the
device's SPA address. After the HMI is started, it reads the ref-
erence in the device and searches for the ReXX.dat file in the
working directory with the same reference. Providing the file is
found, the HMI uses the data in the file and does not have to
read the data in the device. The connection is thus established
much more quickly.
As the device data are not normally saved via the remote HMI,
the ReXX.dat files have to be expressly copied to the station di-
rectory after everything has been finally configured.
As soon as the device data have been loaded, the HMI displays
the main menu, to which the menu item 'SPAComm' has been
added.
