– CAM state register
The CAM-state-register (attribute 113d) is used to represent the cam switching states
depending on the position of the encoder shaft. For this purpose, the value of the
register must be broken down in binary notation (see below). Each bit of the octet from
attribute 113 shows the status of a specific switching position.
The following example shows a CAM-state-register with the value 89h:
