XM-320 I/O Message
Formats
The XM-320 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-320 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-320 module provides one pre-defined (static) data format of the Poll
response, as defined in Assembly instance 101. 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 8 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 65.
