3.5.15 GIO (get input/output)
With this command the status of the available general purpose inputs of the module can be read out.
The function reads a digital or analogue input port. Digital lines will be read as 0 or 1, while the ADC
channels deliver their 12bit result in the range of 0… 4095.
GIO IN STANDALONE MODE
In standalone mode the requested value is copied to the accumulator (accu) for further processing
purposes such as conditional jumps.
GIO IN DIRECT MODE
In direct mode the value is only output in the value field of the reply, without affecting the accumulator.
The actual status of a digital output line can also be read.
Internal function: the specified signal pin is read.
