7 Profile specific process data objects
Two process data objects (PDO) are implemented in the device. One is used for
asynchronous transmission and the other one for the cyclic transmission functions.
The output position value is transmitted in binary code:

7.1 1st transmit Process-Data-Object (asynchronous)
This PDO transmit the position value of the measuring system in an asynchronous
way. The cyclic timer is stored in Index 1800h Sub 05h and in index 6200h.

7.2 2nd transmit Process-Data-Object (cyclic)
This PDO transmit the position value of the measuring system in a cyclic way (on
request). Request by remote frame and/or sync telegrams.
