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.

0: Invalid
1: valid
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 complete the aforesaid
operations by setting the VX1 delay.
When F17.09=xxxxxxx1, the VX1 status depends on the bit 0 of the function code
F17.10.
The status of the virtual input terminal is directly dependent on the function code.
This is mainly used for remote control by the host. The remote control terminal can be
used to enable and disable the input terminal status directly with the function code 0x41
by changing the value of F17.10 through communication.
