1.2.2.2.1 Short Description
The processor module is a central unit for AC500 with high performance.
Each processor module can operate up to 2 communication modules via its communication
module interface. The communication modules are mounted on the left side of the processor
module. On the right side of the processor module, up to 10 digital or analog I/O modules can
be attached. Each of these I/O modules requires its own I/O terminal unit, whose type depends
on the module type.
For a description of the mounting, disassembling and the electrical connection
of the I/O modules, please refer to the System Assembly, Construction and
Connection chapter
Chapter 2.6.3.3 “Mounting and Demounting the Pro-
cessor Module PM595” on page 1266.
WARNING!
Removal/Insertion under power
The devices are not designed for removal or insertion under power. Because of
unforeseeable consequences, it is not allowed to plug or unplug devices with
the power being ON.
Make sure that all voltage sources (supply and process voltage) are switched
off before you
–
connect or disconnect any signal or terminal block
–
remove, mount or replace a module.
Disconnecting any powered devices while energized in a hazardous location
could result in an electric arc, which could create a flammable ignition resulting
in fire or explosion.
Make sure that power is removed and that the area has been thoroughly
checked to ensure that flammable materials are not present prior to proceeding.
The devices must not be opened when in operation. The same applies to the
network interfaces.
