Configuration of the PROFIBUS DP Slaves Connected via FBP¶
A PROFIBUS DP Slave can be added by right-clicking on Profibus_Master_x (Profibus_Master) and selecting Add object.
The slave configuration parameters can be edited in tab PROFIBUS slave:
Note
All times for the PROFIBUS parameters are given in bit time [tBit]. The bit time is the result of the reciprocal of the baudrate:
tBit = 1 / baudrate in [bit/s]
The conversion from milliseconds into a bit time is shown in following formula:
tBit = Time in [ms] * baudrate in [bit/s]
The following parameters are available:
| Parameter | Default | Value | Meaning | Parameter (Remark 1 Configuration of the PROFIBUS DP Slaves Connected via FBP) |

| Identification | ||||
| Station address | 1 | 0…126 | Station address of the PROFIBUS DP slave device. | StationAddress |
| Watchdog | ||||
| Watchdog control | Enabled | Disabled | The PROFIBUS Slave does not utilize the Watchdog Control Time setting. | SlavePrmData -> wdFact1 |
| Enabled | The PROFIBUS slave utilizes the Watchdog Control Time setting in order to detect communication errors to the assigned Master. When the Slave finds an interruption of an already operational communication, defined by a Watchdog time, then the Slave carries out an independent Reset and places the outputs into the secure condition. | |||
| Time (ms) | 400 | 0…2540 | Watchdog time in [ms]. The default value depends on the number of slaves attached to the master and their configuration. |

Remark 1:
The parameters in this column are shown in tab PROFIBUS Slave Configuration which is only visible if the parameter Show generic device configuration views is activated (open the Options dialog window with menu item Tools -> Options …, parameter is located under section Device editor):
The table shows all configuration parameters which are available for the device.
Remark 2:
Click Groups... to open the Group Properties dialog window. The relevant group(s) for the slave device can be selected by activating the corresponding item in the dialog window. The selection(s) can be confirmed with the OK button. To cancel the selection, use the cross symbol on the right of window title bar.
