Alarm Cry-out is enabled by selecting the port on which alarms will be broadcast. Selections are:
0 – Disabled, 1 - COM1, 2 – COM2
9.
The time in minutes between Cry-Outs.
10.
Set to 1 when it is time to Cry-Out.
11.
Cry-out checks the Data Carrier Detect (DCD) line to see if the communications channel is quiet
before it initiates a Cry-out. This keeps it from transmitting when the Host is trying to
communicate with the unit. Some communications equipment may not support DCD and with
nothing connected to the DCD terminal, the DCD input might float to a true state keeping Cry-out
from transmitting alarms. Setting this register to 1 will instruct Cry-out to ignore DCD.
12.
If you correct the situation that is generating an alarm, you can then set this register to 1 to clear
the alarm so that it will not Cry-out at the next scheduled Cry-out time. This command however,
causes the system to scan immediately for alarms and if there was another existing alarm
condition, it will Cry-out immediately instead of waiting for the next scheduled Cry-out time.
13.
The amount of time left before the next scheduled Cry-out as specified by the Cry-out
Frequency.
14.
How the alarm operates. ‘Normal’ indicates that while the alarm variable’s value is in alarm, an
alarm is indicated, even after the alarm is acknowledged by the host. ‘One Shot’ indicates the
alarm is logged when the alarm variable’s value goes into alarm, after the alarm is
acknowledged by the host the alarm is not logged again until the value leaves the alarm state
and then returns to the alarm state. ‘Current State’ indicates that before the alarm is sent to the
host (either by a exception request or by cryout) the current value of the alarm variable is
checked and if the current value indicates that the alarm variable is no longer is alarm, no alarm
is logged and sent to the host.
15.
Delay sending cryout alarms for the specified time period in hours.
16.
The structure of each entry when read:
typedef
struct
/* Alarm Log Record */
{
byte num;
/* Alarm Number */
uint16 user_code;
/* User's Alarm Code */
byte type;
/* Variable Type */
VAR_VALUE data;
/* Alarm Value */
VAR_REF ref;
/* Variable Reference */
JULIAN dt;
/* Date/Time of Alarm */
char
appl_id[11];
/* id of application */
} ALARM_REC;
where VAR_REF is:
typedef
struct
/* Variable Reference */
{
byte app;
/* Application Reference */
byte array;
/* Variable Type */
byte index;
/* Variable Index */
