3) Protocols

yourprotocol.php (This script is called as much as possible)

• $CMD_POOLING The command that request your com. app.
  You should use the ${'ADR'.$invt_num} variable as inverter adress (IP or RS-485), ${'PORT'.$invt_num} variable as /dev port and ${'COMOPTION'.$invt_num} as parameter options.
  Those $invt_num variables are taken from the config/config_invtX.php generated files (X inverter number)
  

• $CMD_RETURN The return string. Always initialize to allow the 'Communication Error' test

• $IxV, $IxA, $IxP are strings values. Voltage, Amperage and Power. (x range 4)

• $GxV, $GxA, $GxP For grid phase x values (x range 3)

• $FRQ Grid frequency

• $EFF Inverter efficiency

• $INVT, $BOOT Inverter temperature, booster (dc/dc) temperature

• $KWHT is the total counter (a Wh precision is needed)

• $RET should equal 'OK' only if the dataset is complete

yourprotocol_startup.php (Called once a day few minutes after daily start-up)

• $CMD_INFO Command that generate a info text file
• $CMD_SYNC Command that sync inverter's time

yourprotocol_check.php (Called each x minutes defined by the admin)

• $STATE Command that return inverter's status

• $ALARM Command that return inverter's 'alarms'

• $MESSAGE Command that return inverter's 'messages'

• $ILEAK Return the ileak value in mA

• $RISO Insulation in Mohm

• $PPEAK Return the peak power of all time in W

• $PPEAKOTD Peak power of the day

• $RET should equal 'OK' if all correct

../config/sensor/your_sensor.php

• $SR irradiation sensor value W/m²
