Parameterization and commissioning
CX8030 / CX803140 Version: 1.6
6.3.3 PROFIBUS
6.3.3.1 CX8030
6.3.3.1.1 PROFIBUS Interface
PROFIBUS communication takes place via the D-sub port X101. The CX8030 supports the automatic slave
scanning function. To this end the GSD file must be stored in the folder \TwinCAT\IO\PROFIBUS.
Note
No ADS via PROFIBUS
The CX8030 does not support the ADS via PROFIBUS. The program download and debug-
ging can take place exclusively via the Ethernet interface.
PROFIBUS address (only in slave mode)
The PROFIBUS address can be assigned using the DIP switch or permanently assigned in the System
Manager. If the address is permanently defined, the address switch is ignored (see DIP switch [}32]).
GSD file
The GSD file for PROFIBUS devices should be stored in the TwinCAT folder \TwinCAT\IO\PROFIBUS.
DpState
You can display the status of the PROFIBUS communication via the DpState and ascertain whether the
slave is exchanging data (DpState=0) or whether there is an error or a problem.
0 = No error
1 = Station deactivated
2 = Station not exists
3 = Master lock
4 = Invalid slave response
5 = Parameter fault
6 = Not supported
7 = Config fault
8 = Station not ready
9 = Static diagnosis
10 = Diagnosis overflow
11 = Physical fault
12 = Data-Exchange left
13 = Severe bus fault
14 = Telegram fault
15 = Station has no resources
16 = Service not activated
17 = Unexpected telegram
