Slave New Diagnostics Flags (Word n+17 to Word n+24)

Status Controlled
by
ON Unit If the bit corresponding to a slave device address is ON, it indicates that
this slave device
• is allocated to the PROFIBUS Master Unit, and
• is exchanging I/O Data with PROFIBUS Master Unit.
In this case, the PROFIBUS Master Unit must be in the CLEAR mode or
the OPERATE mode.
OFF Unit If the bit corresponding to a slave device address is OFF, it indicates
that the slave is not in Data_Exchange with this PROFIBUS Master
Unit, due to the fact that
• the slave device is not allocated to this PROFIBUS Master Unit, or
• the slave device has been allocated to this PROFIBUS Master Unit,
but is forced out of Data_Exchange mode, due to a communication
error, or
• the slave device has been allocated to this PROFIBUS Master Unit,
but is not responding,
• the slave device has been allocated to this PROFIBUS Master Unit,
but is it has temporarily been disabled,
• the PROFIBUS Master Unit is not in CLEAR or OPERATE mode
The Slave New Diagnostics flags indicate for each slave device if it sent a new
diagnostics message to the PROFIBUS 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 device address.
