varx_specs

Purpose:

Configure real variable transfers for the var_transfer program by processing a specification file.

Enter:

varx_specs [filename]

Where:

filename

Optional. Specify the pathname of a specification file. The default filename is /specs/varx_specs.NNN where NNN is the test cell name.

Example:

varx_specs
The above processes the default specification file and send messages to all the var_transfer applications that are running. Depending on the contents of the file, one of the instances will process the specifications.

Spec file format:

############ example spec file ############
#
# registered name of the instance of var_transfer which will
# process these specifications
# the @REG_NAME specifications is optional – default name is “VarTransfer”

@REG_NAME
   VarTransfer

#input_label  output_label   bias      gain     filter
   my_label    my_out_label   0        1.0      0.0
   ..etc

# All variables specified above the first @SYNC_EVENT keyword
# will be processed at the process interval specified on the
# command line of the var_transfer task – those below @SYNC_EVENT
# will be processed only when the sync event is received

#Note: the specified sync events must exist before this spec
#         file is processed

@SYNC_EVENT
   my_sync_ev

#input_label  output_label   bias      gain     filter
   my_ins1    my_outs1   0        1.0      0.0
   ..etc

# Variables specified after this keyword will be
# processed whenever the “my_sync_ev2” event is received

@SYNC_EVENT
   my_sync_ev2

#input_label  output_label   bias      gain     filter
   my_ins2    my_outs2   0        1.0      0.0
   …etc

Notes:

The var_transfer program uses specifications from this program to transfer variables with optional bias, gain, and filter.
