EA10 SERIES

SunSpec Combiner and Input String Event Flag Values

The string combiner specific flags are defined here. Any number of events may be active at the same time, and as a result the SC_Event value is implemented as a bit-map.
The bit-map values specifically called out as SC_EVENT_COMBINER_ only apply to the combiner unit as a whole.

Event Name

Flag Value

Description

SC_EVENT_CURRENT

0x00000008

Current out of range. Set threshold in Sensor LED Blink Threshold register.

SC_EVENT_REVERSED_POLARITY

0x00002000

Reversed polarity detected

SC_EVENT_COMM_ERROR

0x00008000

Subsystem Communication Error

Vendor Event Flags

The vendor specific string combiner flags are defined here. These flags are specific to the EA10 and are not specified by SunSpec. They appear in the SC_Event_Vendor
(summary) and SC_Input_Event_Vendor (per string) registers. Any number of events can be active at the same time, and as a result the SC_Event_Vendor event value is
implemented as a bit-map. The SC_Event_Vendor field applies to the combiner as a whole, while the SC_Input_Event_Vendor field applies to the specific string combiner
input. An event in one or more of the SC_Input_Event_Vendor registers associated with each string activate the same event in the summary SC_Event_Vendor register. Users
trigger on the combiner level SC_EVENT and then drill down to the SC_Input_Event_Vendor level to determine which string(s) are at fault. The bit-map values specifically
called out as SC_EVENT_COMBINER_ only apply to the combiner unit as a whole.

The SC_EVENT_LED_ bits indicate the state of the LED indicators on both the sensing module and communications units. These are bi-color LEDs that can be off, red or green.
When the indicator is on, it can either be on constantly or blinking. See LED Indicators section.
