<p>Sorry for mixing this topic with profibus questions: I'm trying to get the acyclic communication working but I can't figure out where to find all information to get the ID used for the function blocks below:<br/>
RALARM <br/>
RDIAG <br/>
RDREC <br/>
WRREC </p>
<p>Scope Name Type Initial Comment <br/>
Return ID DWORD <br/>
Input EN BOOL TRUE <br/>
MASTER BYTE ID of the DP system <br/>
SEGMENT BYTE Number of the DP segment <br/>
STATION BYTE Number of the DP-slave(station address) <br/>
SLOT BYTE Slot number</p>
<p>The station byte is the slave dp address but where do I find the values for the rest?`</p>
<p>I'm running with the EL6731 Profibus master from Beckhoff.</p>

I just got the ID of the Profinet buscoupler from the Profinet name <br/>
(in my case of a Phoenix Contact buscoupler = "il_pn_bk.ID")<br/>
and with the function IoDrvProfinet.SUBSLOT_ID, I got the ID</p>
<p>Thanks again Mr Schwellinger</p>

(Im currently testing it on a Raspberry Pi)<br/>
To be able to configure the IO Link sensors, I need the acyclic communication to work.<br/>
=I need to use the functions RDREC and WRREC.<br/>
For these to work correctly, I need the adress of the I/O module in the form of a DWORD<br/>
For Profibus communication there is a functionblock, CommFB.ID, that I have used before.</p>
<p>dwAdrID := CommFB.ID(EN := TRUE,<br/>
MASTER := PN_Master_ID, <br/>
SEGMENT := BYTE#16#0,<br/>
STATION := iSTATION, <br/>
SLOT := iSLOT);</p>
<p>1) Is acyclic communication implemented of the Raspberry?<br/>
2) Can I use the CommFB.ID functionblock?<br/>
3) In that case, how do I find out the STATION number of a Profinet buscoupler?</p>
