The VME status file is a data file in the processor’s memory. It is used to
store VME setup and status information. It contains the setup information
for the continuous copy to/from VME. The VME status file number is
placed in word 15 of the PLC-5/VME status file. This file should be an
unused integer file. The PLC-5/VME processor accesses word 15 only at
initialization; thus any change of word 15 after initialization will have an
unpredictable effect.
Your programming software package should provide you with the
following types of capabilities:
monitor processor status
clear minor and major faults
monitor VME status
See your programming software documentation for specific information
about how to get to and use the software screens.
