Short Description

The processor modules are the central units of the control system AC500. The types differ in their performance (memory size, speed etc.) Assortment. 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’s network interface type (1x ETHERNET, 2x ETHERNET or ARCNET).

Each processor module can operate multiple communication modules through its communication module interface (defined by the terminal base).

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 connected to the I/O bus. Each I/O module requires a suitable terminal unit depending on the module type.

Terminal bases, terminal units, I/O modules, communication modules and accessories have their own technical descriptions.

Each processor module can be used as:

  • Stand-alone processor module
  • Stand-alone processor module with local IOs
  • Remote IO Server
  • Remote IO Client

Note

The processor modules (except PM591-2ETH) can be used as a slave with

  • PROFIBUS
  • DEVICENET
  • CANOPEN

The processor modules are powered with 24 VDC.

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

  • 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.

Note

The processor module PM595 is described in a separate device description PM595.
