Hello. I'm looking for a description of the Organization Block 50. I use "System Software for S7-300/400 System and Standard Functions" as a reference but I cannot find a detailed description of this OB, it's Local Data and temporary variables.

Where can I find this information?

Hello,

OB50 is actually not a valid OB for S7-300/400-CPU. Does your CPU support an OB50 at all? (see Ctrl-D)
What kind of CPU do you have?

My task doesn't depend on CPU model. I'm working with SSL-ID W#16#0222 (Interrupt Status) and one of it's indexes (according to the S7-300/400 manual) is W#16#0032
(DP interrupt). It should denote OB50. I've seen this OB in other manuals as "Global Data interrupt" but without additional details.

Sorry, I don't know OB50 and SSL-ID W#16#0222. Is a record SSL-ID W#16#0222 index W#16#0032 available/readable? With "DP-Alarm" maybe they mean OB55, OB56 and OB57?
(For what task is it necessary to read SSL-ID W#16#0222 "Interrupt Status"?)

I don't have a record with SSL-ID W#16#0222 index W#16#0032. I need this SSL-ID for traffic dissection purposes.
Thank you for the response in spite of the result.
