Function Keys
The APM 10 has 6 powerful user definable function keys.
The user can define actions for 3 events: when the key is pressed, while
the key is pressed and when the key is released.
Multiple tasks can be assigned to a single
keystroke making it a powerful tool in the machine control environment.
It is also possible to assign actions for a combination of two keys
pressed simultaneously.
The possible tasks include coil operations (such
as coil on, off, toggle, hold on or hold off), register operations (such
as write constant to registers, copy tags etc.), screen operations (such
as go to a specific screen, go to the next defined screen, go to
previous screen etc.), alarm operations (acknowledge alarm, print alarm,
select next / previous alarm etc.) and so on.
Each key can have different functions depending
on the active screen. This can be used effectively to navigate easily
through the application. Access to function keys can be protected using
a password.
APM 10 has two user definable LEDs for the
purpose of annunciation. The LEDs are mapped to a user definable
register in the PLC.
Changing Data
Data entry objects can be defined in the Prizm where data is to be
changed. Since every user wants different ways to edit the data, the
unit provides full flexibility in cursor control and key operations
during data entry. The default assignments as shown on the keypad can
also be used for data entry.
A bit / coil status can also be edited in an
interactive manner. The key toggles the bit status and ENT key accepts
the selection. Text for the object (for example, RUN when bit is ON and
STOP when bit is off) changes on the display to indicate the selected
bit status making it very user friendly.
Screens
The user can define as many screens as allowed by the unit memory. A
list of tasks can be defined before showing a screen, while showing a
screen as well as after hiding the screen. This allows proper
initialization of parameters, if needed.
Various types of objects can be placed on the screen. They include
simple text objects, data display (bit type text, register data show,
message objects based on a value in the register), alarm object, data
entry object (bit type and register type) etc.
Data display and data entry objects support various different data
formats such as integer, unsigned integer, long integer, float etc.
which makes it easy to use in almost any application.
Data can also be displayed in a bar graph format.
Alarms
The user can define up to 16 alarms. For faster communication with
the PLC, it is possible to define all the 16 alarms as consecutive bits
(1 word) in the PLC. It is possible to log alarms (optional) along with
the on/off times and retrieve them later. The alarm object is used to
view the alarms with many flexible view options. Keys can be assigned to
acknowledge alarms, print or view next / previous alarms etc.
Setup
The APM 10 is setup on an IBM PC using the Prizm software which is
provided free of cost.
