Representation The following information describes the representation of the DLOG instruction
block.
The following figure represents the block structure.
The following list provides detailed information about inputs to, outputs from, sand
the node content of DLOG.
Inputs
DLOG has two possible control inputs:
The top input should remain ON until the operation has completed
successfully or an error occurs.
The middle input stops the active operation of the instruction block.
Note that data format and its frequency of writing is determined by your
application. Note also that the DLOG block operates only with AMD flash cards.
For information about Compact Accessories for PCMCIA cards, refer to Compact
Accessories, p. 193.
Outputs
DLOG can produce three possible outputs:
The outputs from the top node goes ON while a DLOG operation is in
progress.
The output from the middle node goes ON if DLOG detects an error during a
DLOG operation.
The output from the bottom node goes ON if DLOG operation is successfully
completed.
