FbEq Description
Mailbox interface
Defines the address where the input data will be written to. If the
address is greater than 10000, an offset of 10000 is subtracted
from it, and the result is forwarded to the Inverter control program.
Example: If the address is 2402, the write command will be
targeted to Master control program parameter 24.02 Q POWER
RED. If the address is 11901, the write command will be targeted
to Inverter control program parameter 19.01 DATA 1.
1 = 1 Address to be written. The address format is: (group number *
100) + index number.
Defines the value which will be written to the address defined by
parameter 28.01 WRITE
1 = 1 Data value
Defines the address where the output data will be read from. If the
address is greater than 10000, an offset of 10000 is subtracted
from it, and the result is forwarded to the Inverter control program.
Example: If the address is 134, the read command will be
targeted to Master control program parameter 01.34 PV MODULE
DC MEAS. If the address is 10110, the read command will be
targeted to Inverter control program parameter 01.10 DC
VOLTAGE.
1 = 1 Address to be read. The address format is: (group number * 100) +
index number.
1 = 1 Shows feedback for the write operation:
• Original write address if the write operation was successful
• Zero if the write operation was not successful.
1 = 1 Shows the data that has been read from the given read address.
Note: If the read operation is not successful, the data in this
parameter is not valid and it must be discarded.
1 = 1 Shows feedback from the read operation:
• Original read address if the read operation was successful
• Zero if the read operation was not successful.
