“Managementkanal 3 Byte E/A“.
13.Choose as third identification from the dialogbox “ID“ the identification the appro-
priate length for user flag bytes.
14.If the AS-i Control user memory field is bigger than 16 bytes the identification has

The fields “I Addr.“ and “O Addr.“ hold the start addresses for the AS-i data, the
management channel and the user memory bytes. The easiest way to set the ad-
dresses is with “Auto Addr.“
