FC310x as master
FC3101 and FC3102 31 Version: 3.0
ADS-WriteControl for local FC310x addressing (port 200)
AdsState DeviceState State of the
FC310x
Description
STOP (6) 0x00 RUN (5) This will stop the FC310x, 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 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)

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-specific, unique error code (High Word, -> chapter

3.6.2 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 keyword "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 [ } 58] 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 mapped in ADS-Write:
