Allocation of the Device Name

General Information

There are 2 possibilities for the allocation of the device name of the modules CI50x-PNIO and CM589-PNIO(-4):

• Allocation of the device name via DCP (Engineering Tool needed)
• Allocation of the device name via address switches (without Engineering Tool)

For the start-up of PROFINET, the address information “MAC address” and an unique “device name” is sufficient. The allocation of the IP address is performed via the IO Controller automatically during start-up of the bus communication.

Caution

:strong:Malfunctions due to wrong device name settings!

Each device name can only be used once in a network to be explicit.

Make sure that each device has an unique device name.

Note

A maximum of 256 PROFINET IO devices can be used within the same network. The ABB CM579-PNIO PROFINET IO Controller can handle up to 128 PROFINET IO Devices.

Allocation of the Device Name \ via DCP

The allocation of the device name via DCP is standard for PROFINET networks. For this possibility of allocation, it is absolutely necessary to set both address switches must to “00”.

A device name set via DCP will be also present after a restart of the device (is stored permanently).

Note

If the address switches are not set to “00”, the device name via DCP is also stored permanently. But after a restart, the stored device name is not used.

Allocation of the \ Device Name via Address Switches

The AC500 PROFINET IO RT Devices (CI50x-PNIO and CM589-PNIO(-4)) are equipped with 2 rotary switches to set an explicit name to the IO Devices before commissioning. No engineering tool is needed.

The device gets its name (including the fixed part of the device name) directly from the setting of the switches (01h…FFh). This name can be used directly within the device configuration.

This name is for example:

ci501-pn-xx / cm589-pn-xx

ci501-pn / cm589-pn is the fixed part of the device name and xx represents the position of the rotary switch (0..255d or 0..FFh).
