Note: communication via Profinet/Profibus adapter ACCON-NetLink-PRO compact produced by company DELTALOGIC has been verified. Communication with multiple S-300 series PLCs on Profibus worked after firmware upgrade of adapter to version V2.54 (31. march 2015) with adapter's BIOS version V2.39 (7. June 2011). When the adapter's firmware was version V2.37 (8.august 2011), communication could not be correctly established.

Note: the protocol has a "big endian" data representation.
