Note
When simulate is active, the output block no longer writes values to the transducer block. If the Output Blk Timeout period is
exceeded, the transducer block may move the valve to the Zero Power Condition depending on the configuration of the Output
Block Timeout Alert.
The SIMULATE_D [10] parameter has three components:
D Simulate Enable_Disable determines whether the function block will use the actual valve position value and status,
or Simulate Value and Simulate Status.
D Transducer Value and Status reflect the process values provided by the transducer block.
D Simulate Value and Status may be entered by the user when Simulate Enable_Disable is set to Enabled.
To use simulate, first install the simulate jumper in the terminal box, then set Simulate Enable_Disable to Enabled,
then enter the desired values for Simulate Value and Status.
When SIMULATE_D [10] is Enabled, the Simulate Active bit of the BLOCK_ERR [6] parameter is set (refer to the Block
Errors description). When the simulate jumper is installed, the Simulate Jumper bit of the transducer block parameter
SELFTEST_STATUS [78] is set.

Description
Data Type: Unsigned16
The revision level of the static data associated with
the function block. The revision value will be
incremented each time a static parameter value in
the block is changed.
Data Type: Octet String
The user description of the intended application of
the block.
Data Type: Unsigned16
The strategy field can be used to identify grouping
of blocks. This data is not checked or processed by
the block.
Data Type: Unsigned8
The identification number of the plant unit. This
information may be used in the host for sorting
alarms, etc.
