Motion Block
Description
The Input Bit blocks returns the state of the input bits referenced by the parameter. A non-zero value represents a high voltage and a 0 represents a low voltage. This blocks returns a single bit which is useful for making decisions. However host communication benefits from packed information. Using a controller resident application program it is an option to consolidate input bit status into a single user word if desired.
Escapes
A Parameter Out Of Range Escape Code will be generated if the parameter references an input beyond the range of the controller.
Examples
This block list shows a prompter message if an input transitions to true:
However this would be more readable if Named IO is used instead:
This block list starts blinking when a switch connected to input 1 is pushed and continues until the switch is released.
Again, compare with the improved readability of Named IO. Note that the condition of "on" or "off" can be selected:
