8.2 Description of the AS-i Line and AS-i Slave Calls
Overview
This section describes the calls that can be sent by the PROFINET IO controller to
the IE/AS-i LINK. With these calls, the IE/AS-i LINK provides the complete
functionality of the master profile M4 of the AS-i master specification. The
IE/AS-i LINK can be configured completely by the PROFINET IO controller using
calls.
Which calls can be executed can be found in the following two tables:
S Table 8-4 lists the calls for the “AS-i line” level.
S Table 8-5 lists the calls for the “AS-i Slave” level.
S Table 8-6 contains the calls for the “AS-i slave” level that are supported only by
slaves complying with AS-i specification V3.0 (CTT slaves).
The IE/AS-i LINK also supports calls with indexes higher than 0x8000 (decimal
32768), as described in the PROFINET specification IEC 61158.
