5 Alencon Communication Environement (ACE)
The PODD can be used in different configurations, depending on application and
communications needs. A full communications system, designed by Alencon, is sometimes
referred to as ‘ACE’.
Communications Protocol:
Alencon devices support Modbus RTU communications to the PODD. The PODD converts
Modbus RTU to Modbus TCP for central PODD or SCADA integration.
Communications Hardware:
All configurations use Cat5e or newer ethernet cables of STP type. Each string of Alencon
devices will be terminated with an RJ45 terminator to reduce noise and reflections. More
information on wiring and cable spec can be found in section 7.4.1.
5.1 Single PODD
In this configuration, a single PODD is connected to a string of Alencon devices which will
supply power and transmit data to the PODD using Modbus RTU. The PODD will also be
connected to a local area network and provide a user interface to communicate with the
Alencon devices directly.
