Block Errors
Table 4-79 lists conditions reported in the
BLOCK_ERR [6] parameter. Conditions in italics are
not applicable for the DI block and are provided only
for your reference.

Action on Failure

In case of hardware failure, FIELD_VAL_D [17], PV_D
[7], and OUT_D [8] change to a Bad status and the
BLOCK_ ERR [6] parameter shows Process Variable
has Bad Status. If the transducer block mode is Out of
Service, the status of FIELD_VAL_D [17], PV_D [7],
and OUT_D [8] is set to Bad:Out of Service.

Simulation

To support testing of the control strategy, you can
enable the SIMULATE_D [9] parameter. Normally the
measurement value and status used for
FIELD_VAL_D [17] in the DI block reflect actual
process values as provided by the transducer block.
When the SIMULATE_D [9] parameter is enabled,
value and status used for FIELD_VAL_D [17] is
supplied by the user manually. To enable simulation in
the DI function block, the simulate jumper must be

installed. For information on the installation of this
jumper, see the Installation section.
The SIMULATE_D [9] parameter has three
components:
D Simulate_D enable/disable determines whether
the function block will use the actual process 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 enable/disable is set to enabled.
To use simulate, first install the simulate jumper in the
terminal box, then set Simulate_D enable/disable to
enabled, then enter the desired values for Simulate
Value and Status.
