CJ-series PROFIBUS Master Unit Operation Manual for NJ-series CPU Unit (W509)
The Slave New Diagnostics flags indicate for each slave device that it sent a new diagnostics message
to the PROFIBUS Master Unit since the last time it was read or cleared by the NJ-series controller unit.
An Array data type is used to access individual slave diagnostic status with the Device Variable
*_SlvNewDiag.
The flags are also allocated to a block of eight CIO words and each bit in the block corresponds to a
device address. The flags are allocated to a block of eight CIO words and each bit in the block corre-
sponds to a device address.
Bits 00 to 63 of LWORD-type *_SlvNewDiagL and bits 0 to 61 of LWORD-type *_SlvNewDiagH Device
Variable for CJ-series Unit correspond to slaves at node addresses.
