FC310x - PCI Cards for PROFIBUS

Master

As master, the PROFIBUS DP, PROFIBUS DPV1, PROFIBUS DPV2, S5-FDL-AGAG communication and the PROFIDRIVE-PKW Interface protocols are supported.

 

PROFIBUS DP

A summary of the PROFIBUS-DP master functions follows:

Function
Description
Standard DP
The PROFIBUS DP chapter describes the necessary steps for establishing a DP connection (Set_Prm - parameter, Chk_Cfg - configuration) and for the exchange of user data (Data_Exchange).
Task synchronization
The Synchronization chapter describes how the TwinCAT task is synchronized with the PROFIBUS cycle.
Slave priorities
The slaves can receive telegrams with differing cycle times. The necessary settings are described in the Slave Prioritization/Multiple DP Cycles chapter.
Multiple DP cycles
In order to receive the most recent possible inputs when the task cycles are long, a number of DP cycles can be carried out for each task cycle, as described in the chapter on Slave Prioritization/Multiple DP Cycles.
Diagnostics
The diagnostic facilities are described in this chapter.
Error Reactions
It is possible for different error reactions to be set in the event of a fault (a slave fails or the task is stopped).
Sync/Freeze
Activation of the sync and freeze commands is described in the Sync/Freeze chapter.
Upload Configuration
The slaves connected to the PROFIBUS can be read via Upload Configuration.
Master redundancy
The Master redundancy chapter describes the settings required to have a second master with the same configuration configured as a standby master (as from TwinCAT 2.9).
 
 

PROFIBUS DPV1

A summary of the PROFIBUS-DPV1 master functions follows:

Function
Description
MSAC_C1
The MSAC_C1 connection is established along with the cyclic connection. The Read, Write and Data_Transport services are supported.
MSAC_C2
The MSAC_C2 connection is established independently of the cyclic connection, and can also be used by a second master (while the first one is communicating with the slave over the cyclic MSAC_C1 connection). The Initiate, Abort, Read, Write and Data_Transport services are supported.
 
 

PROFIBUS DPV2

A summary of the PROFIBUS-DPV2 master functions follows:

Function
Description
Equidistance
The DPV2 equidistance functionality is described in the PROFIBUS MC chapter.
 
 

S5-FDL-AGAG Communication

S5-FDL-AGAG communication is described in the S5-FDL chapter.

 
 

PROFIDRIVE-PKW Interface

The PROFIDRIVE PKW protocol is implemented in the PROFIBUS master, and can be used by means of acyclic ADS calls.
