Allocated CIO Area Words

Slave New Diagnostics Flags (Word n+17 to Word n+24)
The Slave New Diagnostics flags indicate for each slave station if it sent a
new diagnostics message to the PROFIBUS-DP Master Unit, since the last
time it was read or cleared by the CS/CJ-series PLC. The flags are allocated
to a block of eight CIO words, and each bit in the block corresponds to a sta-
tion address.
Word n+17 to n+24 [n = CIO 1,500 + (25 x unit number)]

Slave New Diag-
nostics flags
ON
Unit
If the bit corresponding to a slave station address is ON, it indicates that
this slave station
• is allocated to the PROFIBUS-DP Master Unit, and
• has sent new diagnostics message to the PROFIBUS-DP Master
Unit.
In this case, the PROFIBUS-DP Master Unit must be in CLEAR mode
or OPERATE mode.
OFF
Unit
If the bit corresponding to a slave station address is OFF, it indicates
that
• the slave station has not sent a new diagnostics message to the
PROFIBUS-DP Master Unit, since the last time it was read or cleared,
or
• the slave station has not been allocated to this PROFIBUS-DP Master
Unit, or
• the PROFIBUS-DP Master Unit is not in CLEAR or OPERATE mode
Note
In case an allocated slave station is not responding, and there-
fore not sending a diagnostics message, the PROFIBUS-DP
Master Unit itself will provide a diagnostics message to the PLC
CPU containing the mandatory first 6 bytes. This diagnostics
message will then indicate that the slave is not responding.
