Communication Interfaces Sample Clauses
Communication Interfaces. Porto will provide interfaces for accessing offline data, and as such does not need to support any communication interfaces on the application/model level – however, for running workflows and performing automated tasks it is useful to have mechanisms to exchange information between processes. For this purposes there will be scripting extensions that supports asynchronous TCP and/or UDP communication.
Communication Interfaces. Internet Internet There will be several communication interfaces between the subsystems, the high level control system (▇▇▇▇▇▇▇▇▇ PLC) and the monitoring and data storage hardware. These interfaces are shown in figure 2 below.

1) Communication between the high level control system and reformer unit and fuel supply control and monitoring will be implemented by directly connecting the instruments to PLC I/O modules.
2) Communication between the high level control system and PSA subsystem will be implemented preferably by CANopen (to be confirmed).
3) Communication between the high level control system and fuel cell subsystem will be implemented using Modbus RTU. Protocol Modbus RTU physical interface RS-485 baudrate 19200 bps
4) The interface between fuel cell and power electronics will be implemented within the FCS subsystem, and necessary communication is therefore implemented only between FCS and high level control system.
5) When the system is used to supply a 48 VDC telecom site or other similar application, no separate grid monitoring equipment is needed. All necessary monitoring of the load side (voltage, current measurement etc.) is done within the FCS power electronics. There is, however, an option to implement such equipment if the system is used to supply low-voltage AC grid directly.
6) The communication interface between the high level control system and local monitoring & data collection equipment (Cromi server) will be implemented using Ethernet local area network.
7) Remote monitoring and (possibly) cloud based data storage will connect to the local monitoring and data collection equipment using a broadband internet connection. Required connection speed and physical implementation are to be defined based on demonstration site capabilities.
