14.1.6.3 Distance and Angle Measurement Modules
The group of distance and angle measurement modules is divided into three
module types.

1DII
Digital Impulse Interface,

and status byte per signal channel, access to the

For the distance and angle measurement modules, the provider and consumer
status (IOPS, IOCS) of the input or output information are exchanged between the
IO controller and IO device in both directions. With the SSI interface 75x-630,
there is also an option to transmit the input data of the transmitter only. In this
case, the IO device only receives the consumer status (IOCS) from the IO
controller and supplies it with the provider status (IOPS) of the available input
data.
The group of distance and angle measurement modules is divided into the
following submodule types.
