8.2.10 Communication between Components
COSPHI Control
COSPHI Control function is for controlling active and reactive power which is infused from BP Series TL3 OD
inverter to the grid with Prolog, HMI, and XCU at long distance.
Figure 101: COSPHI Control composition
COSPHI Control enables remote control of reactive and active power by setting reference of reactive and active
power by communication between Prolog, HMI, and XCU. Here are the communication methods between
each component.
1. User activates COSPHI Control by Prolog.
2. Prolog sends a COSPHI Control massage at two-minute intervals.
3. HMI interprets the COSPHI Control message from Prolog to modify parameters of XCU.
4. XCU operates according to the modified parameter by HMI.
5. COSPHI (limited to Fixed COSPHI and Fixed Q) has two overlapping parameters for RPC and Internal
modes, and HMI modifies the parameter for RPC mode only. If the relative RPC mode parameter is not
modified longer than five minutes, XCU will operate according to the parameter for internal mode.
