7.2.9.8 Encoders M22-SWD-INC
When used together with touchscreens, M22-SWD-INC encoders open
entirely new input possibilities for industrial applications by implementing the
same type of controls that are now prevalent in consumer electronics. M22-
SWD-INC encoders make it possible to scroll through screen menus, adjust
setpoints, and use an integrated click function to confirm and apply settings
immediately with a simple hand movement.
M22-SWD-INC encoders feature two data profiles that are used to define the
scope of the corresponding cyclical data. Profile 1 has 3 input bytes and 3
output bytes, while profile 2 has 3 input bytes and 1 output byte.
Input points
The encoder's profiles are different from each other in terms of how input
bytes 1 and 2 are interpreted.
Byte 0:
The same for both profiles.
Explanation of CNS, bit 2
CNS / bit 2 is important whenever the user operates the encoder with acti-
vated limits, ￫ Section “ Parameterization”, page 185. This bit is used to
check whether the desired reset value has been successfully applied. The bit
will have a value of 1 by default and will be set to 0 as soon as the module
receives a valid reset value. If there are limits set in parameter bytes 1–4 and
the reset value that is sent falls outside these limits, the bit will be set to 1.
This makes it possible to detect instances in which the sent reset value is
not applied successfully.
