o Text – This simple text object displays static text using one of four predefined
font sizes.
o Date – displays the date using the internal clock
o Time – display time
o Data Display – these objects display the data in bits or registers as numbers or
characters.
Numeric Display – displays the current value in the register
Message Display – displays predefined text strings based upon the value
in the register. Each text string represents a predefined range of values.
Bit Display – displays two predefined text strings according to the state
(On or Off) of the bit.
o Bit Lamp – represents the state of a targeted bit using a predefined shape or
picture (BMP, JPG or GIF)
o Word Lamp – same as Bit Lamp except a Word Lamp represents registers.
o Bar Graph – displays a single bar graph that represents the current value in a
register.
o Multiple Bar Graphs – displays up to four separate bar graphs
o Real Time Trend – displays a trend graph that represents up to four registers.
The graph polls the registers on a timed basis and displays the values as plots on
a time graph.
o Historical Trend – same as above except instead of real-time, the values are
read from the Data Logger.
o Analog Meter – represents a data register as an analog meter.
o Alarm List – displays a list of alarm messages
Grid – Turn on or off a grid displayed on the screens. Use the grid to help align objects.
Snap to Grid – if enabled, objects will align on screen according to the location of the
grid points.
Configure Grid – displays the Configure Grid dialog box, which allows the programmer to
set the size (in pixels) of the grid boxes
Block menu – this menu is for configuring the ladder logic in a Logic Block. Note: this menu is
hidden unless you click on a Block in one of the Logic Block subfolders in the Project Information
window.
New – creates a new ladder logic block in one of the six types of logic block menus:
o Power Up – this is a logic block that executes once when power is initially
applied to the HMC7000
o Main – logic blocks created under the Main menu are executed continuously
during normal operation
o Subroutine – these logic blocks are only executed when called from another
logic block
o Timer Interrupt – logic blocks created under the timer interrupt folder are given
the highest priority of all logic blocks. They are executed continuously according
to the time interval programmed.
o IO Interrupt 1 – this logic block is executed immediately when called (unless a
timer interrupt is in process) and is called by the high speed counter function,
when the count value reaches the preset value set.
