3.2.10.3 System status lists (SSLs) in PROFINET IO
Chapter Content
This chapter explains the following:
• Which SSLs are intended for PROFINET
• Which SSLs are intended for PROFIBUS DP
• Which SSLs are intended for both PROFINET IO and PROFIBUS DP
Compatibility of the new SSLs
For PROFINET IO, it was necessary to create some new SSLs, among other things,
because larger configurations are now possible with PROFINET.
You can also use these new SSLs with PROFIBUS.
You can continue to use a known PROFIBUS SSL that is also supported by PROFINET. If
you use an SSL in PROFINET that does not support PROFINET, an error code is returned in
RET_VAL (8083: Index wrong or not permitted).
