Specification
Fixed allocation of 25 words per Unit.
Start address: CIO 1500 + (25 * Unit number)
Not used
Maximum total size: 7168 words.
I/O Data can be allocated to up to 2 input and 2 output
areas.
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.
The MEMORY AREA READ FINS command can be used to
obtain the last received IO Device Alarm message.
Catalogues the history of error events. The Unit supports
the following Error Log related FINS commands:
• ERROR LOG READ
• ERROR LOG CLEAR
Supported
Maximum packet size is 1500 bytes
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.
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.
