8.2.3 Interface for the output of trending data
The COM2 X72 interface (RJ45-jack on the underside of the AZL5) can also be used as
an output for delivering trending data by setting the Type of Gateway parameter to Data
output.
The interface configuration for Modbus is also active for this.
Data protocol content (data output AZL52):
1. Phase (Byte)
2. Fuel train(byte):
0x00 ⇓ Gas direct injection
0x01 ⇓ Gas pilot ignition 1
0x02 ⇓ Gas pilot ignition 2 (combined with LOgp, HOgp)
0x13 ⇓ Light oil
0x14 ⇓ Heavy oil
0x15 ⇓ Light oil with gas pilot
0x16 ⇓ Heavy oil with gas pilot
3. Position of air actuator (word with offset 100; e.g. value 200 means 10.0°)
4. Position of fuel actuator (word with offset 100)
5. Position of auxiliary actuator1 (word with offset 100)
6. Position of auxiliary actuator2 (word with offset 100)
7. Position of auxiliary actuator3 (word with offset 100)
8. VSD speed (word with offset 100; e.g. value 600 means 50.0%)
9. O2 actual value (word, e.g. value means 20.0%)
10. Actual value (word, e.g. value 1000 means 100.0%)
11. Actual temperature / pressure (word, e.g. value 120 means 120 °C or 12.0 bar)
12. Set temperature / pressure (word, e.g. value 85 means 85 °C or 8.5 bar)
13. O2 trim controller manipulated variable (word with offset 500, e.g. 400 means
10.0% air reduction in relation to ratio control curve)
14. O2 trim controller status (byte)
15. O2 setpoint (byte, e.g. 85 means 8.5%)
16. Flue gas recirculation temperature (word, e.g. value 320 means 320 °C)
17. Flame signal (byte, e.g. value 95 means 95%)
Parameter Type of Gateway (eBus / Modbus / Data output.)
