Maple Systems OIT Family (ASCII) - Manual (Page 40)

OITware 200 configuration software, you can select either left or right justification (line all
characters up with the left or right margin).
Hide Data Entry: This attribute is only available for read/write register monitors. This at-
tribute displays asterisks in the register monitor field instead of the true value in the OIT reg-
ister. Therefore, the current value in the OIT register is never seen by the OIT operator. This
feature is most useful for “restricted access” data.
Read Only or Read/Write: Each register monitor on the screen can either be read only or
read/write. If a register monitor has been configured as read only, the OIT operator will only be
able to read the data in the OIT register being monitored. If a register monitor has been config-
ured as read/write, the OIT operator will be able to change the data in the register monitor on
the OIT’s display, which will change the data in the OIT register being monitored. If the “No-
tify Host of Read/Write Register Monitor Updates” feature is enabled, the OIT will also no-
tify the host of the new value.
The OIT operator will be able to position the focus cursor over any read/write register moni-
tor in a screen. Only those register monitors that the cursor stops on (read/write register mon-
itors) may be altered by the OIT operator. Once the focus cursor is positioned on the correct
register monitor, the OIT operator may alter the contents in several ways:
• By using the delta keys (increment/decrement keys) to “jog” or adjust the value in the
register monitor by preset increments. The jog value that the delta keys use is determined
by the OIT programmer. The delta keys can be disabled completely. The data is sent to the
OIT register immediately, so the OIT operator does not need to press the Enter key. When
the value in the register monitor bumps against the bounds set by the register monitor’s
preset limits, the delta keys are ignored.
• By pressing the Toggle key to alternate between ‘1’ and ‘0’ values (for OIT coil registers
only). If the cursor is pointing to a coil field (either On/Off, 1/0 or ASCII string), the OIT
operator simply presses the Toggle key to change between the two binary values. The data is
sentto the OITregisterimmediately,so the OIT operator does notneed to press the Enterkey.
• By entering a new value. The OIT operator initiates this process by pressing the Clear key
which clears the current register monitor’s contents and begins the data entry mode. Once
the Clear key is pressed, the register monitor field is cleared and the cursor is positioned in
the right most character position of the data field. The OIT operator enters the new value
using the numeric keypad and then presses the Enter key. If the value is within the preset
upper and lower limits (set by the system programmer), the entry is accepted and
immediately written to the OIT register. If the value is outside the preset limits, an error
message is momentarily displayed and the entry is not allowed. Data entry mode is then
exited and the prior screen is again displayed.
