SMV 3000 Transmitter User’s Manual 1/99160
A.5 Configuration, Continued
PED Entries
Each PED parameter is defined in Appendix A of the PM/APM Smartline
Transmitter Integration Manual. While most entries are generic for all
Smartline transmitters, some entries require additional transmitter specific
data for reference. Review the following paragraphs for SMV 3000
specific data to supplement the given parameter definition. The parameters
are presented in the order in which they are encountered in the PED pages.
EUDESC Parameter
Enter the engineering unit description for each PV of the SMV 3000 that
you want the universal station to show for the given PV. (Normally, these
units will be the same as the units entered in the STI_EU parameter, which
is described on the next page.) Please note that for PV4, if rate of flow
calculation is volume flow in cubic meters per hour enter “CM_HR.” For
PV4 flow in any other units enter the engineering unit description, but
then you must provide additional values so that the PV is reranged to show
PV4 in the selected units. See subsection A.6 “PV Engineering Units
Conversions” for more information.
Table A-3 lists the base (default) engineering units for the SMV 3000.
Note that degrees Celsius is default engineering units for the secondary
variable.

STITAG Parameter
Besides serving as a transmitter identification name, the IOP uses the
number of identical STITAG names to calculate the number of PVs
associated with a given transmitter. An STITAG name must be entered for
all SMV 3000 transmitter PVs.
