2.1 General functions
The function parameters can be changed via the operator or service interface with a
personal computer using DIGSI
®
. The procedure is described in detail in the SIPRO-
TEC
®
system description /1/.
2.1.1 Functional scope
The Bay Processing Unit 6MD665 has functions whose scope can be adapted to the
system conditions. Some functions (e.g. control authorisation and mode) are available
by default, whereas other functions must be added within the framework of configura-
tion. The functional scope of the device is specified within the scope of configuration.
2.1.1.1 Description
Configuring func-
tional scope In DIGSI
®
4 dialog box Functional scope, the measuring transducer (various types)
and synchronisation (1 to 8) functions are configured as Enabled or Disabled.
Functions that are configured as Disabled are not processed by the 6MD665: There
are no indications, and corresponding settings (functions, limit values) are not dis-
played.
Functions that are not needed can be hidden.
Note
The available functions and default settings depend on the order variant of the device.
In this way, the entries described in the parameter overview are only then visible under
functional scope if the device was ordered with position 7 of the order number = 1 or
5. Further details can be found in the Appendix.
2.1.1.2 Configuration Notes
Configuration of
Function Scope Configuration settings can be entered using a PC and the operating program DIGSI
®
and transferred via the front serial port, or via the service interface. Operation via
DIGSI
®
is described in the SIPROTEC
®
system description /1/.
For changing configuration parameters in the device, password no.7 is required
(for parameter set). Without the password, the settings may be read, but cannot be
modified and transmitted to the device.
The functional scope with the available options is set in the Functional Scope dialog
box to match plant requirements.
