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 FC310x ADS error codes
[} 37]). The appropriate text message will also be displayed in the TwinCAT System Manager Logger.

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:

Description
FC310x
RUN (5) This will stop the FC310x, i.e. the process data connections to all
DP slaves (Data_Exchange) are removed (with SetPrm,Unlock).
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).
Description
FC310x
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).
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).
