Features and Functions
• A sequence may invoke another sequence, but may not invoke itself
• At the time of sequence definition, a sequence may reference another
• Up to 500 unique sequences can be stored in non- volatile memory.
• While a scan is running (see
• If the command overlap function is enabled, all switching operations
Remote Interface Operation: The following command defines a sequence
named "MYSEQ_1", which closes several channels on the module in slot 1
and opens a single channel on the module in slot 2.

levels of nesting and this is enforced at the time of execution.

undefined sequence; however, at the time of execution an error will be
generated if an undefined sequence is invoked.
Each sequence is limited to 1024 bytes.
prevents use of all channels in banks that contain one or more
channels in the specified scan list (these channels are dedicated to 
the scan). Therefore, if a sequence attempts to operate a channel in 
a scanned bank, an error is generated and the entire sequence will 
be discarded.

overlap function is disabled, all commands within the sequence are
processed in a serial fashion in the exact order in which they are
received. Note, however, that within a single command containing a
