Logix 3400IQ Digital Positioner FCD LGENIM3402-00 – 0/07
Table 10.16 Transducer Block Signature Parameters
Parameter
Description
STROKE_
Stroking time during
OPENTIM
opening
STROKE_
Stroking time during
CLOSEDTIM
closing
* Special Note: Because of the internal Database size limit of 10K within the Fieldbus device, the values for
RAMP_RATE or STEP_TIME may be recalculated to the most reasonable value to allow using the database.
The new value will appear in the parameter after the desired one is written. This is done to prevent accidental
overflow of the database.
It is still possible that the database may overflow, because of timing constraints. If this should happen,
SIG_COMPLETE will not appear, but BEGIN_SIG will be turned off. BLOCK_TEST element 6 will be set to 10
(0x0a) as an error indication. Since this does not affect operation of the positioner itself, no actual error will be
reported over Fieldbus.
