Memory Area Allocation CIO Area words allocated for the
CPU Bus Unit
Fixed allocation of 25 words per Unit.
Start address: CIO 1500 + (25 * Unit number)
DM Area words allocated for the
CPU Bus Unit
Not used
I/O data allocations Maximum total size: 7168 words.
I/O Data can be allocated to up to 2 input and 2 output
Input and output areas can be mapped to CIO, DM, WR,
and HR areas, as well to EM banks. Mapping must be
defined through the configuration software.
FINS Messaging Reading IO Device Alarm The MEMORY AREA READ FINS command can be used to
obtain the last received IO Device Alarm message.
Reading and controlling the error
Catalogues the history of error events. The Unit supports
the following Error Log related FINS commands:
FINS Services FINS/UDP Supported
Maximum packet size is 1500 bytes
Other functions Error history size and storage The PROFINET IO Controller Unit supports storage of up to
80 error events, including time stamps, in volatile memory.
16 error events can be logged in non-volatile memory.
Memory Card backup function Allows PROFINET IO Controller Unit’s Configuration to be
backed up as a file to a Memory Card in the CPU Unit.
The backed up configuration data can later be restored from
the Memory Card into the PROFINET IO Controller Unit.
