UNCTIONS
The Model 430 Programmer provides trigger functions which provide a
means of collecting operational data with a minimum of commands and
directing the output to either or both remote interfaces.

UNCTIONS
The Model 430 Programmer defines a
trigger enable register
,
very similar to the enable registers of the status system, which
controls which data is output and the interface to which the data
is presented. The trigger enable register is defined as shown in
the following table:
To enable the trigger functions, the
*ETE <
enable_value
>
command is written with a decimal value corresponding to the
binary-weighted sum of the desired output. Upon receipt of the
*TRG
command, the Model 430 Programmer places the return
data in the appropriate output buffer(s). Data placed in the serial
or Ethernet output buffers is transmitted immediately. Note that
trigger output data may be placed in both the serial
and
the
Ethernet output buffers if desired, but the formatting and output
selections are common to both.
