In terms of functions, VX1 - VX8 are basically the same; they do not have an actual
physical terminal, but they all have the positive/negative logic function. VX1 - VX4 have
the delay function, with the same terminal status confirmation method; they can be set
respectively. An example is given to VX1 in the following part.
0: VXn Is Same as VYn Output
1: Status to be Set by F17.10
If F17.09=xxxxxxx0, VX1 status and VY1 output status are the same.
As mentioned above, the virtual input terminal has the same status as the
virtual output terminal. At this time, it needs to be used together with the virtual
output terminal.
If F17.19=16 and F17.28=0bxxxx xxx1 (VY1 output status is determined by
the output function status) under default conditions, then when “16: Length Reach”
is enabled, VY1 is enabled and VX1 is enabled as well; at this time, setting this
function as per VX1 (assuming 39: Length Clear) to complete corresponding
operations (clear the length count and reset VY1). Now, the fixed length count
function can start again to realize the repeated processing requirements. If time
interval is needed for repeated processing times, we can realize this function by
VX1 delay.
If F17.09=xxxxxxx1, the status of VX1 is determined by the bit0 of the
function code F17.10
The status of the virtual input terminals can be set by the function codes. This
method is mainly used for the remote control of host controller. The remote control
terminal may use the function code 0x41 to change the status setting of F17.10
