PROFIBUS Interface

5 PROFIBUS Variables

In the Variables directory of the LinMot-Talk there is a section \PROFIBUS which contains
some information about the actual state of the PROFIBUS interface:
•
Node Address:
•
Baud Rate:
•
Bus Cycle Time fast:
•
Bus Cycle Time slow:
•
DP State:
NTI AG / LinMot
This shows the used node address, which can be either configured by
the two rotary hex-switches S1/S2 or by parameter settings, as a
decimal number.
The baud rate is auto detect. This shows the baud rate, which was
found on the bus. Zero means no baud rate found.
This shows the actual cycle time in µs. The fast Cycle time is updated
up to 10ms.
This shows the actual cycle time in ms. This value can be used when
the bus cycle time is extremely large (>10ms).
This shows the actual state of the LinMot internal DP-State machine:
- (0) Initialise: The firmware is initialising the PROFIBUS Interface
- (1) Searching Baud rate: The detection of the baud rate is in
progress.
- (2) Wait for Parameter Telegram: No valid parameter telegram has
been received.
- (3) Wait for Configuration Telegram: No valid configuration telegram
has been received.
- (4) Ready for Data Exchange: The PROFIBUS is ready for Data
Exchange, but the master has not done the transition.
- (5) Data Exchange: The PROFIBUS is running and exchanging
cyclic data with the master.
