Parameter description

7 Parameter description

7.1 General

The section is based on:
Fieldbus Foundation Specification "Function Block Application Process Part 1 to 3"
Revision 1.4.
Fieldbus Foundation Specification "Transducer Block Application Process Part 1 to 2"
Revision PS 3.0.

7.2 Device Description (DD)

The following Device Description files are required for integrating the device described into
host systems:
Device Description:
Capabilities File:
You can order these Device Description files on disk (3 1/2") from SAMSON under the pro-
duct number 1400-7705 or you can download them from the Internet at www.samson.de
or www.fieldbus.org.
Note: The file < Positioner 3787_Rev2.fhx > is required for integration into the System Del-
taV from Fisher-Rosemount, instead of the capabilities file from Fieldbus Foundation.
This file can be provided by SAMSON.

7.3 Notes on the parameters

All times specified in the Resource Block are in 1/32 ms units in accordance with the
Fieldbus specification Version 1.4.
In the Device Description Library supplied by the Fieldbus Foundation on which the Device
Description of the Type 3787 is based, these parameters are incorrectly shown with the ms
unit. The numerical values supplied by the device should, however, always be interpreted as
units of 1/32 ms.
Due to the same reason, the IO_OPTS parameter in the AO Block displays "Fault state to
value" as "Fault state type".
Several parameters can only be altered in certain modes (see "Access" in Parameter descrip-
tion).
Therefore, it is important that the Target Mode is set and not the Actual Mode.
