Simulation
To support testing of the control strategy, you can enable the SIMULATE_D [17] parameter. Normally, the valve
position value and status used for READBACK_D [16] in the DO block reflect actual process values to the nearest 5%, as
provided by the transducer block. When the SIMULATE_D [17] parameter is enabled, value and status used for
READBACK_D [16] is supplied by the user manually. To enable simulation in the DO function block, the simulate
jumper must be installed. Refer to page 15 of the Installation section for information on the installation of this jumper.
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.
