Master

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

Description
The PROFIBUS DP [} 11] 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).
The Synchronization [} 12] chapter describes how the TwinCAT task is
synchronized with the PROFIBUS cycle.
The slaves can receive telegrams with differing cycle times. The necessary
settings are described in the Slave Prioritization/Multiple DP Cycles [} 14]
chapter.
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 [} 14].
The diagnostic [} 16] facilities are described in this chapter.
It is possible for different error reactions [} 16] to be set in the event of a fault (a
slave fails or the task is stopped).
Activation of the sync and freeze commands is described in the Sync/Freeze
[} 15] chapter.
The slaves connected to the PROFIBUS can be read via Upload Configuration
[} 34].
The Master redundancy [} 38] chapter describes the settings required to have a
second master with the same configuration configured as a standby master (as
from TwinCAT 2.9).
Description
The MSAC_C1 [} 31] connection is established along with the cyclic connection.
The Read, Write and Data_Transport services are supported.
The MSAC_C2 [} 31] 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.
Description
The DPV2 equidistance functionality is described in the PROFIBUS MC [} 25]
chapter.
