7.3.4 Tag and Device Information
If these are specified when ordering, the designated
Tag No. and device information are set and
shipped.
Tag No. and device information can be checked as
follows.
■ Procedure to call up the tag No. and device
information
- Device Tag (Software Tag)
This is specified when writing characters
(up to 16 characters) that differ from those
specified in Tag No. to the amplifier tag.
For details on how to confirm this, refer to
subsection 6.4. ”Connecting to the Field
Wireless Network”.
- Tag Description
This is a universal parameter to store the
comment that describes the content of the
tag located in the TRANSDUCER and AI
blocks.
■ Limitation of Device Information
When changing the device information, input
the information based on the following limitation
on the number of characters.
- Message function (up to 32 characters)
TRANSDUCER block : Tag Description
AI1/AI2 block : Tag Description
7.3.5 Setup the Integral Indicator
As for the integral indicator display, either the
temperature, voltage, resistance or the % value
of the temperature, voltage, resistance can be
selected and displayed. The display is in the output
format of the process value.
Specify AI block to display on the LCD.
■ LCD display parameter (Display Selection)
Select AI block to display on the LCD from AI1
or AI2.
■ Call up the display parameter (Process Value
Type)
AI1 block: Configuration: Process Value Type
Either actual target value (Direct) or % (Indirect)
can be selected.
7.3.6 Power Saving Mode Setting
This function is applicable for dual input type with
a detachable antenna, Amplifier housing code
8 and 9. Enabling the power saving mode on
prolongs the battery life of the transmitter, in which
the transmitter's measurement and calcutattion
are suitable for general use with a gradual change
in the process and ambient temperature. On the
other hand, when the power saving mode is set to
off, the transmitter is capable of a steep change in
the process and ambient temperature wtih its high
responsiveness trading off of the battery life.
■ Procedure to call up the power saving mode
TRANSDUCER block : Power Saving Mode
Off: Disable
On: Enable
7.3.7 Unit
The unit for the process value is set at the factory.
The specified unit of the input sensors set (°C if not
specified).
When the unit of the temperature, voltage, and
resistance is displayed, set the Process Value Type
parameter to actual target value (Direct).
And sensor type set by the sensor type setting
parameter (Lin Type) must be corresponded with
the unit displayed.
When using the resistance temperature sensor or
the thermocouple sensor, unit displayed set °C or
others, using voltage, set mV, and using resistance,
set ohm.
The unit can be set by following the procedure
below.
■ Procedure to call up the unit parameter (Units
Index)
AI1/AI2 block: Scale : Units Index
To change the unit, select the desired unit from
the displayed unit list.
7.3.8 Measurement Range
The unit parameter is set at the factory before
shipment if specified at the time of order. To change
the measurement range, follow the procedure
below.
■ Procedure to call up the lower limit setting
parameter (EU at 0%)
AI1/AI2 block : Scale : EU at 0%
