5.12. Remote HMI
5.12.1. Summary
The firmware provides facility for controlling RE.316*4 devices
grouped according to stations. All the HMI functions are avail-
able. User access via the remote HMI to such functions as 'Load
setfile', 'Test function', 'Time synchronisation' and 'SPA commu-
nication' can be restricted.
We do not recommend loading and downloading 'Setfiles' via a
modem link as all the device settings will be lost should the line
be interrupted during file transfer.
Remote HMI facilities:
· local control of a device via the interface on the front
· control of several devices in an SPA_BUS loop via a modem
and the SPA-BUS interface
· control of several devices in an SPA_BUS loop via the SPA-
BUS interface
· control of several devices in an SPA_BUS loop via an SRIO.
In this operating mode, the HMI sets the SRIO clock and syn-
chronises the device clocks.
· control of several devices in an SPA_BUS loop via a modem
link and an SRIO. In this operating mode, the HMI sets the
SRIO clock and synchronises the device clocks.
· safe operation since the simultaneous access by local and
remote HMI's is excluded
· system of access rights to restrict the operations possible on
the HMI
· event recording transferred to a pre-defined individual di-
rectory for each device
· convenient HMI user shell for easy control.
5.12.2. Modem requirements
A modem used in conjunction with the remote HMI must be suit-
able for asynchronous operation and the interface baud rate
must be independent of the line baud rate. It must be possible to
set the interface baud rate to correspond to the SPA/SRIO baud
rate.
