• Can CX-Supervisor be used with Industrial Touchscreen PCs (IPCs)?
Absolutely. CX-Supervisor is designed for use with Omron's DyaloX
Touchscreen IPC but can be used with other manufacturers. It has special
features especially for Touchscreen PCs:
• Edit animations have option to enter data from a popup keyboard to
allow typing direct on the screen.
• CX-Supervisor Login dialog box has a popup keyboard.
• Project setting for 'Large dialog boxs' to increase font size on high
resolution touchscreens giving a larger contact area.
Projects can be built on a development machine and deployed using
"Create Runtime Install Disk" to copy required files to a shared drive or
USB memory stick.
It is also commonplace to copy a shortcut to the SR2 application to the
'Startup' folder. If the keyboard is to be detached see also "How To Enable
Automatic Login in Windows"
• How do you enable automatic login in Windows?
The initial Windows security screen can be bypassed which may be useful
on systems with no keyboards, or systems that should start automatically
on boot up. Information on how to achieve this is published by Microsoft
on its Web site - see Q253370 How to Enable Automatic Logon in
Windows 2000 and Q315231 How to Enable Automatic Logon in Windows
XP.
Please note the cautions included on registry editing and security.
• What is the functionality of "On Condition" scripts?
ON CONDITION scripts will be executed whenever any of the points
mentioned in the expression change value (or are re-evaluated as a result
of being input) AND the result of the expression is TRUE.
For example, if the expression was $Second, then the script would be
executed 59 times a minute. The expression would be evaluated every
second when the value changes, but when $Second was 0, the result of
the expression would be FALSE.
• What is the scan time of "On Condition" scripts?
There is no scan rate directly associated with the script processing itself.
In fact the execution is instant, as soon as the value has changed. The
script expression will be checked whenever any of the points are updated
(a value is input, or the value is changed in some way).
CX-Supervisor is an "event-driven, object-oriented" system meaning is
that it is actually the points changing that force the script code to re-
evaluate the expression. They do this whenever a point changes value, or
is re-evaluated (e.g. a value is received from the PLC at the point's usual
scan-rate). This removes any sampling error associated with polling and
also makes CX-Supervisor very efficient.
