Notes to SIPROTEC objects
1.3.1
Changing the setting group
•
In order to change the setting group, the value "1" = ON must be transmitted to the
corresponding register.
•
Switching ON one setting group automatically switches OFF the current active set-
ting group.
•
Transmission of the value "0" = OFF is insignificant for the change of the setting
group and is refused by the device.
•
A change of the setting group is only possible via Modbus if the parameter
Change
to Another Setting Group
(parameter address = 302) has the value
Protocol
.

1.3.2
Cooling medium temperature
•
The cooling medium temperature is transferred in per cent (%) to the 7UM62.
The protection device must be informed about the 100 % corresponding tempera-
ture using parameter
49 Temperature for Scaling
(function
49 Thermal
Overload
, parameter address = 1608).
•
The temperature value via Modbus is only taken into account and shown at the
SIPROTEC device if the parameter
49 Temperature Input
(function
49
Thermal Overload
, parameter address = 1607) has the value
Fieldbus
.
•
Unlike measured values in input direction, the identification "Overflow" or "Invalid"
is not indicated with the value -32768 (ref. to manual "SIPROTEC Communication
module, Modbus - Communication profile").
If an evaluation of the measurement status of the cooling medium temperature is
required then the indication
“>Fail.Temp.inp”
(>49 Failure temperature input,
internal object no. = 1508), routed to “Destination system interface” in the
DIGSI
Configuration matrix
, has to be used for this separately.
