First word (Word n): Set with the Support Tool when the screen is created.
The PT Status Status Notify Area is set by choosing Direct or Direct Specify In-
formation under the Expansion Function from the Screen List on the Support
Tool.
Any changes in PT status are written to the PC PT Status Notify Area.
The PT Status Notify Area is configured as ten consecutive words, as shown in
the diagram below.
First word (Word n): Set with the Support Tool when the screen is created.
The screen number of the screen displayed on the PT is written to this word. Si-
multaneously, the PT Status Screen Switch Strobe Flag is set ON (1). After the
PC is notified, this flag reverts to OFF (0). Checking the status of this flag pro-
vides a simple method of checking if the PT display has switched.
The number of the numeral table is written to this word when the numeral table
contents change due to PT switch operation. The input value appears in the
word allocated for the appropriate numeral table. As the number of the numeral
table is written, the PT Status Number Setting Strobe Flag is simultaneously set
ON (1). After the PC is notified, this flag reverts to OFF (0). Checking the status
of this flag provides a simple method of checking if a number has been input from
the PT.
The bits shown in the following table are turned ON or OFF in response to the PT
operating status and battery level.
