Description
Customization of the variable name.
Allows definition of a correction factor for display of the measurement in the
Monitoring page. The default factors to be configured for each TM of a T200
series 3 are as follows:
- Phase current: "Direct/10"
- Mains voltage: "Direct"
es not change the format of the measurement sent in
Note: This factor does
the protocol frame.
NB: For compatibility of measurements with the T200 series 1 and 2 or with
an L500 type supervisor, configure as follows:
- Phase current: "Direct
- Mains voltage: "Direct*100"
- Also check that the "8-bit
bit measurement" box is checked in the
"Miscellaneous" section of the "Settings/Automatic
Settings/Automatic control"
control page of the
CONTROL module concerned by this TM.
Logical address assigned to this variable by the T200. This is in fact the
logical name of the variable (TM+No.) (unmodifiable).
Allows a variable to be associated with a defined class. It is advisable to
group together those variables having an information link in the same class
so as to make reading in the pages of
o the Web server easier.
Defines the level of accessibility of this variable (administrator, operator,
monitoring). The level of accessibility is defined with the login and password
used for access to the Web server.
Internal address assigned to this variable by the T200. This is in fact a
Modbus address for the internal link between the CONTROL module and the
COM card (unmodifiable).
Address providing access to this variable in read/write mode from the
Supervisor
rvisor via the protocol. The address is specific to each protocol used
(Modbus, IEC, DNP3).
The basic T200 includes for each variable the configuration of the external
addresses corresponding to the installed protocol.
An address set to "-"" is made inaccessible

from the Supervisor.

this
Max. value is used for calculation during measurement retransmission to the
SCADA system or for display in the Monitoring page. (see note 2 below).
NB: The value configured influences the precision of the measurement.
Should correspond to the minimum value that can be taken in practice by the
measurement value. For "Raw" or "Normalized" type measurements, this
Min. value is used for calculation during measurement retransmission to the
SCADA system or for display in the Monitoring page. (see note 2 below).
NB: The value configured influences the precision of the measurement.
