PROFINET® slave¶
In this tab-sheet some additional communication parameters will be edited. The parameters which are already used in other tab-sheets are grayed out here.
See also section PROFINET® timing in chapter Configuration of a ABB PROFINET® IO Device.
The following parameters are available:
| Parameter | Default | Value | Meaning | Parameter |
|---|---|---|---|---|
| Phase | 1 | 1…Reduction ratio | Defines the part of the SendCycle at which an IO frame is sent. | Phase |
| Watchdog factor | 3 | 1 …65535 | The Watchdog time is calculated as Watchdog time = SendCycle * Watchdog factor. The transfer of a IO telegram is always checked of the consumer side. Within this time the next IO telegram must be received by a consumer. Otherwise it is checked if the Datahold has been expired too. | Watchdog factor |
| Datahold factor | 3 | 1 …65535 | The Datahold time is calculated as Datahold time = SendCycle * Datahold factor. If the Watchdog time has been expired, the Datahold time will checked. If the Datahold time also has been expired, the substitution values of the IOs will be used. For RT_Class_1 communication Datahold time and the Watchdog time are usually configured with the same value. | Datahold factor |
| Frame send offset | 0xFFFFFFFF (means: as soon as possible) |
1…2^32 - 1 | Only available for RT Class 3 Data-RTC-PDU | Frame send offset |
