Communication with the Host
TRIG A Signal as Reading Trigger
The trigger is used to cause the V530-R160 to read data and the data is written to the program-
mable controller.
Set the
Read Area
to
None
.
Time the input of TRIG A considering the image processing time and data output time, allowing suf-
ficient leeway. An error will occur if the next input occurs before communications have been com-
pleted.
While the command is being executed,
the BUSY signal of the parallel I/O interface is ON.
TRIG A
A timeout error occurs if there is no response within
5 seconds and it is assumed that the line is broken or
the programmable controller is not working correctly.
An error message is displayed on the screen and the
ERR signal of the parallel I/O interface is turned ON.
