B.4.6.3 Control events from the command line
Starting EnerVista 650 Setup from the command line allows the transfer of control events to a file. For this purpose, we
need to indicate the event number from which event controls are to be retrieved, and the file where they are to be stored.
Communication can be established via serial communication by specifying the port and access baud rate, or via Ethernet
through the IP address and communication port. The relay number from which events are to be retrieved must also be
indicated.
For executing this Operation, 6 parameters must be written, for both cases, serial communication or Ethernet.
SERIAL COMUNICATION
EnerVista 650 Setup –e event number " File name" –com port: baud_rate relay_number
E.g.: EnerVista 650 Setup –e 6 “C:\GE Power Management\EnerVista 650 Setup\files\Events\eventos.txt” –com 1:19200 254
ETHERNET COMMUNICATION
EnerVista 650 Setup –e event number " File name" –ip “IP address”: port relay_number
E.g.: EnerVista 650 Setup –e 6 “C:\GE Power Management\EnerVista 650 Setup\files\Events \eventos.txt” –ip
192.168.37.240:502 254
The created file format looks as follows:
#Event Number, Event Id,Event Text,Event Data Time,Event Value(0,1)#
6,1,Local,09-Sep-2003 17:42:40.782,1
7,1,Local,09-Sep-2003 17:42:43.236,0
8,2,Remote,09-Sep-2003 17:42:43.236,1
B.4.6.4 Event status request (alarms)
To retrieve events that have been configured as alarms, see the following addresses:
0xF000: 24 registers, the first 12 indicate the status active/inactive and the last 12 indicate the status of
acknowledged/not acknowledged.
0xF018: 12 event alarm status (active - not active, acknowledged – not acknowledged) registers.
0xF024: date and hour of the event bits starts (groups of 16 dates and hour must be asked for).
To obtain an instantaneous snapshot of all events and alarms states, do the following:
1. Read the head of events FIFO (0x03FF).
2. Read the addresses above.
3. Finally, read the head again to confirm that it has not changed. If it had changed, restart the procedure.
NOTE: The message must request the address and the quantity of bytes indicated in each zone. If another quantity is
needed, it will not respond with the requested data.
B.4.6.5 Acknowledging alarms
For acknowledging the alarms we must simply write message to the 0xf324 address with 12 data registers. Each bit
means an event, if we want to acknowledge an alarm, its corresponding bit must be set to ‘1’ (in order within the 192 bits).
NOTE: it must be borne in mind the independence of the acknowledgement condition, for its reading and its change,
depending on the communication channel
There are 6 channels:
LOCAL: by MMI or COM-2 (front and rear accessible).
