closed state/valid in the open state
The terminals VX1 to VX8 essentially have the same function, but there are no
corresponding physical terminals actually. They all have the positive and negative logic
functions. The terminals VX1 to VX4 have the delay function, and their statuses can be
confirmed in the same way. They can be set separately. The terminal VX1 is taken as an
example below.
VX1-VX8
status setting
options
0: the VXn status is the same as VYn
output status
1: status set by F17.10
When F17.09=xxxxxxx0, the VX1 status is the same as the VY1 output status.
As stated literally, the status of the virtual input terminal is the same as that of the
virtual output terminal, so this should be used in conjunction with the virtual output
terminal.
If F17.19=16 (reach the length) and F17.28=xxxx xxx1 (the VY1 status depends
on the output function status) under the default conditions, and “16: reach the length”
is valid, the VY1 output and VX1 synchronization will be valid. The corresponding
operations (length count clearing and VY1 output status resetting) can be performed
according to the VX1 setting (assuming “39: length clearing”). Then the fixed length
count function can be enabled again to meet the requirements for repeated processing.
If there are certain intervals between repeated processing procedures, you can also
