XM-123 I/O Message
Format The XM-123 module supports Poll, Change of State (COS), and Bit-Strobe
I/O messages. The Poll response message is used by the XM module to
produce measured values, and the COS message is used to produce the Alarm
and Relay Status. The Bit-Strobe message is used by a master device to send a
trigger event to all the XM slaves on the network.
Poll Message Format
The XM-123 Poll request message contains no data. The Poll response
message can contain up to 31 REAL values for a total of 124 bytes.
The XM-123 provides two pre-defined (static) data formats of the Poll
response, as defined in Assembly instance 101 and 102. It also provides a
dynamic Assembly instance, instance 199, with which you can define a custom
data format for the Poll response. The dynamic Assembly instance can contain
any of the measurement parameters included in Assembly instance 101, as well
as several of the alarm and relay configuration parameters.
The default Assembly instance is 101 and the default size is 36 bytes. You can
change the Assembly instance and define the custom Assembly instance using
the configuration software. Refer to I/O Data Parameters on page 74 for
details.
