● Bit assignment of the handwheel
– A setpoint is not specified for the handwheel.
– After start-up of the HMI device, the bytes "n+4" to "n+5" are set to zero.
Turning the handwheel triggers positive or negative pulses, depending on the direction of rotation. The number of
positive pulses are stored in bits I0 to I7. The number of negative pulses are stored in bits D0 to D7. The values are
entered in binary format, where bit 0 is the lowest and bit 7 is the highest valued bit.
A complete handwheel revolution yields 50 pulses.
– Every pulse of the handwheel is added to byte "n+4" or "n+5", depending on the direction of rotation. There are no
negative values. When the possible value range is exceeded, there is an overflow:
If a value of 255 is increased by one pulse, a value of 0 results.
● Bit assignment of the override rotary switch. With Gray coding, the following codes are assigned to the individual switch
positions:
