# Fieldbus Parameters General

Field | Description | Default value
--- | --- | ---
Fieldbus type | Select the fieldbus type from drop-down menu: DeviceNet EtherNet/IP ProfinetIO Profibus CC Link CC Link IE EtherNet/IP M40 | Undefined
Update interval | Set how often a Process Data Frame should be sent. The value is expressed in milliseconds. Minimum value is 100 ms. |
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
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
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
Sync on task selected |  | 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
Byte order Acyclic Data | Select which order of bytes is used for the acyclic data: Intel (little) Motorola (big) | Motorola (big)
Load async data automatically | Selection switch On-Off. When turned On, the first and only package of the async data is automatically loaded. When enable this function, the fieldbus master must ensure that it is done reading data before starting a new cycle. | Off
To controller | Total receive Process Data Frame. The frame size is a combination of all the virtual station receive frames. The size is expressed in number of bytes. |
From controller | Total transmit Process Data Frame. The frame size is a combination of all the virtual station transmit frames. The size is expressed in number of bytes. |
