IM 208DP - Master - Deployment at CPU 21x
Via the IM 208 master modules you may connect up to 125 Profibus DP
slaves (up to 16 at DPO) to one System 200V CPU.
The master communicates with the slaves and transfers the data areas via
the backplane bus into the address area of the CPU. There may occur a
maximum of 1024Byte input and 1024Byte output data.
With firmware versions < V3.0.0 there are only 256Byte available for input
and output data.
With every boot procedure of the CPU, this fetches the I/O mapping data
from all masters.
The alarm processing is activated, i.e. a IM 208 error message may
initialize the following alarms, causing the CPU to call the according OBs:
•
Process alarm: OB40
•
Diagnostic alarm: OB82
•
Slave failure: OB86
As soon as the BASP signal (i.e. "
B
efehls
a
usgabe
sp
erre" = command
output lock) comes from the CPU, the IM 208 sets the outputs of the
connected periphery to zero.
Note!
After a slave failure, the process image of the inputs is in the same state
than before the failure.
At deployment of the IM 208 Profibus DP master, please make sure that
this has a firmware version V3.0.0 or higher; otherwise it is not deployable
with a CPU 21x with firmware version V3.0.0 or higher.
The according firmware version is to find on the label at the backside of the
module.
Having questions to the firmware update, please call the VIPA support
(support@vipa.de).
More detailed descriptions to the inclusion into your CPU are to find in the
documentation of your CPU.
