System Integration
In the configuration example above, the control byte of the VS 130 was set to
output address 0 and the status byte of the VS 130 was set to input address 0 of
the CPU (DP master, slot 1). If these addresses are in the process image of OB1
(process image partition "OB1 PI"), you can work here in OB1 with process image
access (for example "A I0.6" or "S Q0.1"). If this is not the case, you must work
with direct I/O access (for example "L PIB 0").
In the configuration example above, the start of the 16 word long consistent
communication area of the Vision Sensor VS 130 was set to input address 1 and
output address 1 (slot 2). If these addresses are in the process image of OB1
(process image partition "OB1 PI"), you can work in OB1 with process image
access (for example "L IW 2", "T QB 1") without violating the consistency. If, on
the other hand, these addresses are not in the process image of OB1, you must
access the communication area of the VS 130 using SFCs 14 "DPRD_DAT" and
15 "DPWR_DAT" to ensure consistency.
The Vision Sensor VS 130 detects the transmission rate on PROFIBUS
automatically. Even if the transmission rate has changed, this is detected
automatically. The following values possible:
•
9.6 kbps
•
19.2 kbps
•
45.45 kbps
•
93.75 kbps
•
187.5 kbps
•
500 kbps
•
1.5 Mbps
•
3 Mbps
•
6 Mbps
•
12 Mbps
The PROFIBUS address of the VS 130 is set in the Settings > Ports > DP Addr.
menu of the processing unit. Possible values are 1, ... 125.
Changing the PROFIBUS address via PROFIBUS is not supported.
If you assign parameter values to the Vision Sensor VS 130 via PROFIBUS, you
can only set its default values (all zero). If you enter values other than zero here, a
slave diagnostic message is generated ("Invalid DP parameters"). If you are using
an S7-CPU as the DP master, a diagnostic interrupt is triggered (No OB82 start,
because CPU is in STOP): "Faulty module" is entered in the diagnostic buffer and
the "SF" LED is lit.
If problems occur entering the device in HW Config, refer to Chapter 7.
