The Objects

The Decrement Value Button supports binary, BCD and signed integer data
types for the lower limit. This object does not support a separate sign bit or
decimal point, or scaling. Although PanelBuilder allows the user to enter a
positive 8-digit minimum value, the data type together with the number of
bits assigned determines the range of PLC values.
The following table details the different data types and their ranges:
Table 10.H
Decrement Value Button Data Types and Values
This data type: Supports this range of values:
Binary 0 - 65,535
BCD 0 - 99,999,999
Signed Integer 0 - 32,767
If the value is already at or below the minimum, the value is not changed.
Auto-Repeat
If a button is pressed for more than the time specified by the button’s
Auto-Repeat Start Delay, the value automatically decreases by the amount
specified by the Amount per Decrement at the rate specified by the
Auto-Repeat Rate.
the Auto-Repeat rate may be set for 0 to 20 per second; auto-repeat is
disabled if the rate is set to 0
the Auto-Repeat Start Delay may be set for 0.2 to 2.5 seconds
the Amount per Decrement is an integer value in a range of 1 to 10000;
the default is 1
IMPORTANT: If you change one or more of the Decrement Value Button
default settings (4 per second Auto-Repeat Rate, 400 msec Auto-Repeat
Start Delay and an Amount per Decrement of 1), the application will only
be compatible with Version 2 and later PanelView firmware.
Often, Increment and Decrement buttons are used together to control the
same PLC address. Since they don’t display the value of the address, a
Numeric Data Display could be used to display the value at the same
address.
IMPORTANT: The Decrement Value button is a retentive object. Your
PanelView terminal will retain the current PLC input address value even
after you’ve powered down the terminal or switched to Configuration
mode. The preset value of this object can be defined and changed using
PanelBuilder.
