Short Description

The Processor Modules are the central units of the control system AC500. The types differ in their performance (memory size, speed etc.). Each Processor Module must be mounted on a suitable Terminal Base. The Terminal Base type depends on the number of Communication Modules which are used together with the Processor Module and on the Processor Module-own network interface type (1x Ethernet, 2x Ethernet or ARCNET).

Each Processor Module can operate up to 4 Communication Modules through its Communication Module Interface. The Communication Modules are mounted on the left side of the Processor Module on the same Terminal Base.

On the right side of the Processor Module, up to 10 digital or analog I/O expansion modules can be attached which are automatically interconnected by the I/O-Bus. Each of these modules requires its own I/O Terminal Unit, whose type depends on the module type.

Terminal Bases, Terminal Units, I/O modules, Communication Modules and accessories have their own technical descriptions AC500 Device Description (Hardware) Hardware S500.

Each Processor Module can be used as:

  • bus master within the control system AC500 together with several field buses and networks
  • stand-alone Processor Module

Note

The Processor Modules (except PM591-2ETH) can be used as a slave with

  • PROFIBUS®
  • DeviceNet
  • CANopen®

The Processor Modules are powered with 24 V DC.

Warning

:strong: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 are

  • connecting or disconnecting any signal or terminal block
  • removing, mounting or replacing a module.

Disconnecting any powered devices while energized in a hazardous location could result in an electrical arc, which could create a flammable ignition resulting in fire or explosion.

Be sure that power is removed and that an area has been thoroughly checked to insure that flammable materials are not present prior to proceeding.

The devices must not be opened when in operation. The same applies to the networking interfaces.

The Processor Module PM595 is described within a seperate device description PM595.
