2.1 General
The PPC-57 PC-based system can monitor and sample the data of
several traditional PLC controllers simultaneously. It is able to
take full advantage of a wide range of available software pro-
grams, and upgrading can be achieved quickly and easily with the
use of various optional modules.
Customizing the PPC-57 is a simple matter. The DRAM, power
supply and I/O adapter are all readily accessible by removing the
front or rear panel.
Warning! Verify that all power sources have been discon-
nected from the PPC-57 before you install or
service it or any of its components or accesso-
ries. No power must be flowing within the PPC-57
at the start of any installation or servicing.
