XM-440 I/O Message
Formats The XM-440 module supports Change of State (COS) I/O messages. The
COS messages are used to produce the Alarm and Relay Status.
COS Message Format
The XM-440 COS message contains two bytes of data as defined in the table
below. The COS data can also be requested explicitly through Assembly
Object (Class ID 0x4), Instance 100 (0x64) Data Attribute (3).
0A Too many alarms associated with a single measurement.
0B Invalid node address in the alarm list.
0C Too many alarms in the alarm list. Or, no alarms in the alarm list.
0D Alarm levels cannot be zero for alarms that are enabled.
0E Too many slaves in the scanner’s input data table.
0F The FMAX and Number of Lines do not yield correct vector calculations.
10 Phase (vector) alarms prohibited with synchronous sampling and more
than 1 pulse per revolution.
11 Order-based bands are prohibited with asynchronous sampling.
12 Unsupported Sensor Type and Channel ID combination.
13 Invalid Alarm Type for the associated measurement ID.
14 Synchronous sampling is required for alarm on synchronous
measurements.
15 Integration is not supported with the Bypass High Pass Filter option.
