2.4.5 Simulation Feature
The PULSAR Model R96 with F
OUNDATION
fieldbus
™
supports the Simulate feature in the Analog Input block.
The Simulate feature is typically used to exercise the opera-
tion of an AI block by simulating a TRANSDUCER block
input.
This feature cannot be activated without the placement of a
hardware jumper. A jumper is provided in the “Run” posi-
tion of the PULSAR Model R96, and is placed under the
display module. To enable the simulation feature, remove
display module and move the jumper to the “SIM” posi-
tion. Refer to figure at left for jumper location.
NOTE: A BLOCK_ERR of “Simulation Active” in the Resource Block
does not mean simulation is active—it merely indicates that the
simulation (hardware) enabling jumper is present.
• The jumper may be removed to eliminate the
BLOCK_ERR and placed back in the “Run”
position.
2.5 PID Block
The PID Function Block contains the logic necessary to
perform Proportional/Integral/Derivative (PID) control.
The block provides filtering, set point and rate limits, feed-
forward support, output limits, error alarms, and mode
shedding.
Although most other function blocks perform functions
specific to the associated device, the PID block may reside
in any device on the network. This includes a valve, a trans-
mitter, or the host itself.
The PULSAR Model R96 FF PID Block implementation
follows the specifications documented by the Fieldbus
Foundation.
2.5.1 Pid Block Parameters
ACK_OPTION
: Used to set auto acknowledgement of
alarms.
ALARM_HYS
: The amount the alarm value must return to
before the associated active alarm condition clears.
ALARM_SUM
: The summary alarm is used for all process
alarms in the block.
ALERT_KEY
: The identification number of the plant unit.
BAL_TIME
: The specified time for the internal working
value of bias to return to the operator set bias.
Place Jumper in the
“SiM” position to
enable simulation.
