Decimal Location
(OIT3200, OIT3250, OIT3600, OIT4400, OIT4450, OIT5400)
This attribute allows you to configure the location of the decimal point in the PLC
Register Monitor. The decimal point is placed the specified number of characters from
the right (for example: 0 = 12345, 1=1234.5, 2=123.45, etc.).
Separator Location
(OIT3100 and OIT4100 Series)
The Separator Location is the same as the Decimal Location described above, with the
additional feature that you can configure any symbol to be displayed in place of the
decimal point.
The Separator field is used to specify which character to place within the Register
Monitor (instead of the Decimal Point), and the Location field is used to specify where in
the Register Monitor the character is placed.
For example, if the Separator character is set as “^”, and the location is set as 2, the value
123456 would be displayed as “1234^56”.
If the selected format does not support a Separator Location, or if the Separator Location
is set to 0, the Separator field is disabled.
NOTE: The Ampersign character (“&”, ASCII 38D) is not allowed as a Separator character.
NOTE:When the Decimal or Separator Location is set to 1 or higher, the field width of the PLC
Register Monitor is increased by one to include space for the decimal point or Separator
character.
To configure the Decimal or Separator Location in a PLC Register Monitor:
1. In the Register Monitor Editor dialog box, in the Attributes group box, in the Decimal
or Separator Location scroll box, select the number of characters from the right to
place the decimal point or Separator character.
Commas
This attribute adds commas every three characters to the PLC Register Monitor (for
example: 1,234,567 would display instead of 1234567).
NOTE:When Commas is enabled, the field width of the PLC Register Monitor is increased by
one for every three numbers in the Number of Digits attribute.
To enable Commas in a PLC Register Monitor:
1. In the Register Monitor Editor dialog box, in the Special Effects group box, select the
Commas check box.
Linear Scaling
Linear Scaling is the term used to describe the process of converting one unit of measure
to another, usually from a machine format to an operator-readable format, so the OIT
operator has the data presented in readily understandable terms. A common application
involves converting analog or digital data into degrees, speed, voltage, or temperature. If
linear scaling is used on a read/write register monitor, the OIT operator can modify the
data in the operator-readable format and it will be converted back into the machine
format before being sent to the PLC register. Linear Scaling is available with the Signed,
Decimal, and Long formats.
