DIGITAL INPUT MODULE BLOCK (DIM)
5-8
11 Mode (MODE)..................................................................................................................... CWR
The mode of the block is determined by configuring and/or writing this attribute. Changing
mode is an informational event.
AUTO 1 The block input is processed using the input module data.
MAN 0 The block input is the manual data form of the result.
12 Field Result (FR) ............................................................................................................... – – R
This is the actual field input value to the instrument.
13 Field Result Quality (FRQ) ............................................................................................... – – R
This data quality field will go BAD if any of the blocks diagnostic errors becomes active.
14 Initial Result Value (R) ...................................................................................................... CWR
This is the field input value to the instrument when an input block is in auto. When the block is
in manual or the I/O is locked, this is the last value written to the result. The result may only
be written if the mode is manual or the I/O is locked.
15 Result Quality (RQ) ...........................................................................................................– WR
This data quality field will go BAD if any of the blocks diagnostic errors becomes active while
the block is in auto. When the block is in manual or the I/O is locked, this is the last value
written to the result quality.
