Call
After proper configuration, the position value is transferred cyclically to the module. Two registers are available per
channel as a buffer. The module confirms successful receipt by setting an OK bit. The EnDat specification does not
specify in which format the parameters must be received. Therefore, the module provides the information in two
ways. Which of the two registers should be used for further processing depends on the parameters being read.
EnDatInfoOKByte
Names (pChannelName):
EnDatInfoOK01
EnDatInfoOK[02…04]
This register's bits provide information about the validity of the latest Info data in the buffer.
