ProTalk Cv2
Two timer ranges, seconds and minutes, are available. The seconds range has a maximum
value of 1638 seconds (27 minutes) with a resolution of 25 msec. For longer times the
minutes range should be used. When set to minutes, the timer has a maximum value of
65,535 minutes with a resolution of one minute. For short times use the seconds timer to
avoid the inaccuracy introduced by the one minute resolution.
When the command to turn on the Timed output has been received and executed, the Cv2
will announce the current state of the output port. If the timer value is set to a short
interval, it is possible that the output will have returned to the Off state by the time the
status is announced.
To make a Timed port operational for remote control it must be configured and enabled in
the Points section.
4.7.2 Points section
After the Hardware ports are configured, use the Points section to specify how activities on
these ports are processed. There are 30 points available for use as either input or output
controls. It is in the Points section that inputs are given the ability to generate alarms and
outputs are enabled to perform remote control functions. Each point can be referenced to any
of the input or output ports. When a port is selected in Points it will have the characteristics
that were set in the Hardware section. If a different type of operation is required for a port, it
must be changed in the Hardware section.
Input and output ports that have been defined as a special function in the Group section (Local
Ack New alarm, Any alarm or Ack received) or in the General section (Modem carrier detect
and Ring out) are not available as general purpose ports.
To access a point for configuration, select the Points button to bring up the summary of the
settings. Status of the 30 points will be shown along with a brief description of their settings.
Highlight the point to be edited, then select it by pressing Enter, double-clicking on the line,
or choosing the Edit Line function from the menubar. Selecting a point will bring up the
dialog box for that type.
Depending on the type of point, the contents of the dialog box will vary. There are a number
of common settings that appear in all of the point dialog boxes:
Common Settings for Points
I/O Port Selection
If you would like to change the type of input or output, select one of the other available
ports. Changing the port will force the point to its default settings and the settings for
the current point will be lost.
If a port is being used for one of the special functions, an abbreviated Function Code
will also be displayed in the port selection list. These are not available as points.
