Sub-Station Control and Deterministic Network Clock Alignment
The 1MRK002305-AAr00 hardware sub-assembly introduces synchronized timebase injection paths designed to track system variables across backplane bus communication velocity Licences. By processing raw external IRIG-B signals down to precise timestamps, the module distributes deterministic time updates over Profinet / EtherNet/IP deterministic networks via the master chassis backplane connector rail.
