The Set Bit Object is used as a button to toggle ON or OFF the state of a bit or coil in the PLC, or a bit in the
HMI local memory (LB). There are a number of different options (Set Styles) available to operate the button
including touch (On, Off, Toggle, Momentary), window open or closed, and backlight on or off.

including touch (Write a constant value, increment or decrement), window open or closed, backlight on or off,
and periodic bounce or jog.
Toggle Switch
The Toggle Switch Object is a combination of the Bit Lamp and Set Bit objects. It is used as a button to toggle
ON or OFF the state of a bit or coil (specified by the Write Address), and as an indicator to represent the ON or
OFF status of a bit or coil (specified by the Read Address) in a PLC register or HMI local memory. It can be
configured with various Switch Styles including Set On , Set Off, Toggle, or Momentary.

The Multi-State Switch Object is a combination of the Word Lamp and Set Word objects. It is used as a button
to change the value of a register (specified by the Write Address), and as an indicator to represent the value in
a register (specified by the Read Address). A Multi-State Switch can display up to 256 different shapes and text
strings, corresponding to register values of 0 – 255.
Option List
The Option List Object provides a way to display a list of names corresponding to values in a register (Monitor
address). The Source of item data selection determines how the Option List operates.
Predefine: The Option List displays a list of items where the item displayed or selected (configured on the
Mapping tab) is determined by the value in a register. Optionally, selecting an item from the list can write its
corresponding value to a register.
Dates of historical data: When data sampling (Data Sampling Object) or Alarms (Alarm/Event Log) are
employed, the Option List can be used to list the dates corresponding to Historical data/event files for
displaying in a Historical Trend Display, History Data Display, or History Event Display.
Item address: Custom text for the Option List can be stored in registers and changed or updated during
runtime.
Control register: Set to 1 to update the item list.
Control register + 1: Determines the number of items in the list.
Item address: The starting address for the item list contents (ASCII or UNICODE).
User account: When “Enhanced Security Mode” is enabled in the System Parameters > Security tab, the
Option List can display the user names in the drop-down list. With the Monitor address pointing to the Control
Address + 2 (Index of accounts register) configured for the Enhanced Security, you can select the user name to
login from the Option List and the corresponding value will be written to the Index register.
