EL673146 Version: 2.8
ADS-WriteControl for local FC310x/EL6731 addressing (port 200)
AdsState DeviceState State of the
FC310x/
EL6731
Description
STOP (6) 0x00 RUN (5) This will stop the FC310x/EL6731, i.e. the process data
connections to all DP slaves (Data_Exchange) are removed (with
SetPrm,Unlock).
RUN (5) 0x00 STOP (6) This will restart the FC310x/EL6731 after a stop, i.e. the process
data connections to all DP slaves (Data_Exchange) are re-
established (normal DP start-up).
ADS-WriteControl for addressing a configured PROFIBUS device (port 0x1000-0x107E)

Description
STOP (6) 0x00 RUN (5) This will stop the slave, i.e. the process data connection to the
relevant DP slave (Data_Exchange) is removed (with
SetPrm,Unlock).
RUN (5) 0x00 STOP (6) This will restart the slave after a stop, i.e. the process data
connection to the relevant DP slave (Data_Exchange) is re-
established (normal DP start-up).
ADS Error Codes
The 32 bit ADS error code always consists of a general ADS error code (Low Word, see ADS
documentation) and a FC310x/EL6731-specific, unique error code (High Word, -> chapter ADS error codes
[}127]). The appropriate text message will also be displayed in the TwinCAT System Manager Logger.
5.1.5.2 PROFIBUS DPV1
On a C1 connection, the master supports the Read and Write services, and on the C2 connection it supports
the Read, Write, Data_Transport, Initiate and Abort services.
C1 Connection (MSAC-C1)
The C1 connection is reserved for the master that cyclically exchanges data with the slave (C1 master). In
order for a slave to be able to use the C1 connection, the slave must support DPV1 (this means that the line
"DPV1_Slave = 1" and the key word "C1_Max_Data_Len" with an appropriate length must be in the GSD
file). If it is also generally necessary to activate the C1 functionality by setting bit 7 in the PrmData byte 0
(see the slave's Profibus [}96] tab) for the corresponding slave (this is done automatically for those
Beckhoff devices that support DPV1).
MSAC-C1-Read is shown in ADS-Read, and MSAC-C1-Write is represented in ADS-Write:
