Communication Features and Methods
The GT100 provides three types of information to the user:
•
system status and/or fault information,
•
data logging information, and
•
oscillography.
System status and fault information can be accessed using the Universal Front
Panel Control Unit (UFCU), via an RS232 connection to a PC or via an RS485/
Modbus connection to a remote monitoring system. Data logging and
oscillography is available via the RS232 or the RS485/Modbus connection.
The GT100 communicates system status information to the user using the
following methods.
•
The Front Panel Control Unit (UFCU) Display
•
PC Connection (Remote) - GT View Graphic User Interface (GUI) Software
required (may require additional hardware)
•
External Monitoring - (Optional) via a RS485/Modbus connection for remote
plant monitoring.
System Status and Fault Reporting
Basic system status and all fault conditions rising from within the GT100
are
reported to the UFCU. The 4-line VFD will display a hexadecimal value and a
brief text description of the fault. Additionally, the CCU2 stores the time and
details of all faults in non-volatile memory for later retrieval.
The fault value is also made available to the GT View Graphic User Interface
(GUI) via the RS485/Modbus protocol and will include a more extensive
description of the fault.
Types of status information include:
•
Current Operating State or Goal State
•
Fault Code (if applicable)
•
Inverter State
•
Line Voltage and Current
•
Inverter Matrix Temperature
•
Inverter Power
•
PV State
•
PV Voltage and Current
•
PV Power
•
Grid Frequency
•
Peak Power Tracker Enabled
