Acyclic Parameter Data
6.1
In addition to the cyclic data exchange, the PROFINET encoder al-
so supports acyclic data exchange. The acyclic data exchange is
transferred over the non-real time channel and is used to read out
and write status information from and to the IO device. The acyclic
data exchange is conducted in parallel to the cyclic data commu-

Identification and Maintenance (I&M functions)
Encoders according to the encoder profile 3.162 also support I&M
The main purpose of the I&M functions is to support the end user
if the device is acting faulty or missing some of its functionality.
The I&M functions could be seen as an electronic nameplate con-
taining common information regarding the device and its manu-
According to the PROFINET specification all IO devices must at
least support the following I&M functions:
For more information regarding additional I&M functions support-
ed by the encoder, refer to chapter 7.14.6.
