Overview
Read this chapter to understand the overall operation of the PLC-5/VME
processor, how you can use it in VME systems, and how its features and
functions relate to those of other Allen-Bradley processors.
PLC-5/VME processors are programmable controllers that bring the
technology of the 1785 PLC-5 processor to the VMEbus environment.
The PLC-5/VME processor is equivalent (in terms of I/O, ladder
programming, and instruction timing) to the standard PLC-5 processor,
except that the PLC-5/VME processor:
plugs into a VMEbus system
has a VMEbus communication interface designed for use with other
VMEbus CPU modules
can access VMEbus I/O modules
has no EEPROM memory module
Figure 1.1 shows examples of the PLC-5/VME processors.
