This function is located on the Utils> Immediate menu. In an application based on a controller with high-speed outputs (HSO) supporting Step Control, Immediate Read HSO Position can be used to immediately record the current value of the Current Position parameter--without regard to the program scan.
This function may be used with Stepper via High-speed Output, and can be called within the following HSC Interrupt routines:
_Interrupt HSC 0,1
_Interrupt HSC 2,3
_Interrupt HSC 4,5v
|
Note ♦ |
Immediate: Read HSO Position CANNOT be used in an 2.5 mS or 1.25 mS Interrupt Routine. |
This function can be used, for example, in a printer application. When the printer head passes a sensor, the program can run a HSC Interrupt routine. The exact position can then be recorded, and used to control future movements
Channels
ERROR: Variable (V570V1040V1210) is undefined.
In most models, the high-speed outputs are located on the Snap-in I/O modules. In these models, in Hardware Configuration, the first HSO is Channel 0.
If the module comprises two output, the second HSO is Channel 1.
In the case of a controller with built-it I/O such as the V570-57-T34, the on-board high-speed output is always Channel 2.
V350/V130
In these controllers, the first HSO is Channel 0, the second is Channel 1, and so on.
