Configuration of the Fieldbus

The fieldbus section consists of information about the fieldbus type in use. This part is hardware dependent and read-only. The configuration section with general settings for the fieldbus in use is possible to edit.

In POWER FOCUS 8 controllers, the fieldbus only works if the Anybus module inside is supported. Only modules coded with an Atlas Copco unique Provider ID are supported and these can only be purchased from Atlas Copco. If a module is purchased from Atlas Copco, then it has a correct Provider ID.

The Atlas Copco Anybus modules supported for POWER FOCUS 8 are the following ones:

  • Profibus M40 (product number 8436 0941 05)

  • DeviceNet M40 (product number 8436 0941 10)

  • EtherNet/IP 2 Port M40 (product number 8436 0941 15)

  • Profinet I/O 2 Port M40 (product number 8436 0941 20)

  • CC-Link M40 (product number 8436 0941 25)

  • CC-Link IE M40 (product number 8436 0941 30)

The fieldbus mapping and the assigning of fieldbus maps to virtual stations are done with ToolsTalk. For more information refer to the ToolsTalk configurations manual.

Description

Default value

Fieldbus type

The supported modules are:

  • Profibus M40

  • DeviceNet M40

  • EtherNet/IP 2 Port M40

  • Profinet I/O 2 Port M40

  • CC-Link M40

  • CC-Link IE M40

None

Connection Status

  • Online: the module is connected.

  • Offline: the module is disconnected.

  • Provider ID mismatch: the module is not purchased from Atlas Copco and therefore it is not supported.

Offline

Set by network

Selection switch On-Off. Determines how the fieldbus module communication is configured.

  • On: Communication parameters set automatically in the fieldbus module. Parameters are determined by the network during the initial connection with the far end station.

  • Off: Communication parameters must be entered during the configuration.

Off

Read result handshake

Selection switch On-Off. When turned On, the setting will affect all virtual stations. The signal Read Result Handshake has to be mapped in the fieldbus configuration.

Any results produced when there are no results to acknowledge will immediately be sent to the PLC.

Results to acknowledge will be put in a queue and when acknowledged it will be cleared and the next result in the queue is sent. The time between the cleared result and the next result in the queue is dependent on the cycle time for the fieldbus set in the general fieldbus settings. If the setting is changed, or if the fieldbus mapping for the virtual station is changed, the results still in the queue will be flushed and not sent to the PLC.

Off

Lock tool when fieldbus offline

Selection switch On-Off. Determines the action taken by the controller if the fieldbus module loses communication with the fieldbus master (PLC).

Off

Sync on task selected

Selection switch On-Off.

If enabled, the fieldbus frame shall be re-synced at task changes.

Off

Byte order Cyclic Data

Select which order of bytes is used for the cyclic data:

  • Set by network

  • Intel (little)

  • Motorola (big)

Set by network

Extended mode

Chooses between the backward compatible152 bytes data mode and the 368 bytes data mode:

  • On: 368 bytes data mode.

  • Off: 152 bytes data mode.

Off

Device address

Specifies the offset in the PLC area of the first byte to write to. Range 0 – 999.
