Rockwell Automation 2708-DH5B2L_DH5B4L Attended Workstation - Manual (Page 32)

Chapter 4
Status Displays
4–2
With the display, the workstation can show two status displays at the same
time. In Figure 4.1, the summary status display is on the left hand side along
with the reserved status on the right hand side. The ‘< 0’(in Figure 4.1) is
associated with the summary status (left hand side), and signifies that the
summary status is status display number zero. The ‘2>’ tells us that the right
hand display is status display number 2.
On the display, as the user selects a new status display, the new status screen
will be displayed on the left hand side, and the display on the right hand side
will be replaced by the one from the left hand side.
Invoking Status Display – Status displays are visible under these
circumstances:
1. After power-up for 15 seconds.
2. When the workstation has a non-zero terminal number, but is without an
A-B VBASIC program.
3. When the A-B VBASIC program terminates.
4. When manually invoked during a power up. This method will present the
status display for 15 seconds after the last keystroke. The A-B VBASIC
program, if loaded, will resume execution after this 15 second status
display.
The Status Display 0 summarizes the status of the other nine status displays.
The numbers 0-9 on the lower line represent the ten status displays. The
information above each number refers to the number under it, i.e. the ’.’ over
the 3 refers to the status display 3 – the time display.
