Model 880 DEPOSITION CONTROLLER

SECTION 6.XX
e page 240 of 276 ^
Description: Requests return of information saved during a process run. The Model 880 saves
information for the last four completed film deposition runs. Each time a new film is completed
the information summary (detailed below) for the run is stored away as the latest result (index 0
for first argument) and the previous latest run (old index 3 before this data log operation
commenced) data is lost. Data recorded as index 0 through 2 before a new run completion are then
accessed by index numbers 1 through 3. Since each log has date/time and run number (and layer
number in the case of sequencing) information stamped with it, tracing which data applies to what
run is simple. The list of processing accounting data element access indices is below.
Returns:
[RZCD_AOK][param_value] if proper log item ident code argument was sent. Exact format of
[param_value] depends on the particular log item for which the data was requested.
[RZCD_ILDV] if improper value for parameter argument.
[RZCD_ILSN] if too many arguments, wrong delimiters, etc.
Read Process Accounting (L)
The set of L commands are used to read the process accounting information from the Model 880
to the host computer. There are 2 parameters that are passed. The first is a single digit from 0 through 3.
This indicates which set of parameters is to be read. The number 0 is the most recent and 3 is the oldest.
The second parameter defines what piece of information will be read. Table 6.18 lists the numbers and
parameters.
