5-1-4 Switching the Screen Display Using the PT Status Control Area
Outline of Host Link and NT Link Operations
Reference
The following describes the procedure used to switch the NT30/30C screen dis-
play by controlling from the PC by using the PT Status Control Area.
The displayed screen can also be switched by other methods: by registering a
screen number for a touch switch or bit memory table entry and then pressing the
touch switch, or by changing the status of the allocated bit of a bit memory table
entry, during operation. For details on these methods, see Stand Alone Function
(pages 157, 187) or the next section, Switching the Screen Display (by Using a
Bit Memory Table Entry.
To switch the NT30/30C screen display by controlling from the PC, write a screen
number at the screen switch setting in the PT Status Control Area.
Screen Switch Settings in the PT Status Control Area
The screens numbered 1997 to 1999 are earmarked for special functions, as
shown below. The display history can be checked by calling them during opera-
tion.
These strobes turn OFF (0) automatically after notification is made to the PC.
The status of operations at the NT30/NT30C can be easily monitored using the
rising edges of these strobes.
When connected to a CVM1/CV series CPU Unit, however, if the PLC is set to
asynchronous operation, it may not be possible to determine the strobe status.
