= O/S
Information on this block such as the block tag, DD revision,
and execution time
1 6001 6101 ST_REV 0 — The revision level of the static data of the DI block. The
value of this parameter is incremented each time a static
parameter value is changed.
2 6002 6102 TAG_DESC (Spaces) AUTO The user description of the intended application of the block
3 6003 6103 STRATEGY 1 AUTO Used by an upper-level system to identify grouping of the
block. Not checked or processed by the block.
4 6004 6104 ALERT_KEY 1 AUTO The identication number of the plant unit. This information
may be used in the host for sorting alarms.
5 6005 6105 MODE_BLK O/S AUTO The actual, target, permitted, and normal modes of the block
6 6006 6106 BLOCK_ERR — — Indicates the error statuses related to the block itself.
7 6007 6107 PV_D — — The primary discrete value (or process value) for execution
of the block’s functions.
8 6008 6108 OUT_D — MAN Indicates the value and status of block’s output.
9 6009 6109 SIMULATE_D 1 (Disabled) AUTO Allows use of values manually set instead of the limit switch
input from the transducer block. When Disable is set for this
value, the block reects the actual input value and status.
1 = Disabled, 2 = Active
10 6010 6110 XD_STATE 0 — Not used in a digitalYEWFLO.
11 6011 6111 OUT_STATE 0 — Not used in a digitalYEWFLO.
12 6012 6112 GRANT_DENY 0 AUTO Option to control access from the host computer and local
control panel to tuning and alarm parameters. Before write
access to a parameter, set the GRANT bit in this parameter
to have the operation right to be granted. Then after write
access, check the DENY bit in this parameter. If the write
access is complete successfully, it is not ON.
13 6013 6113 IO_OPTS 0 O/S Sets the block input/output options.
14 6014 6114 STATUS_OPTS 0 O/S Denes block actions depending on block status conditions.
For DI blocks of a digitalYEWFLO, only bit 0 (Invert: on/off
state inversion) is effective.
15 6015 6115 CHANNEL 3 (DI1)
4 (DI2)
O/S The channel number of the transducer block’s logical
hardware channel connected to this block. Fixed to 3 for
DI1, 4 for DI2 in the DI blocks of a digitalYEWFLO.
16 6016 6116 PV_FTIME 0 s AUTO Sets the time constant of damping for PV_D.
17 6017 6117 FIELD_VAL_D — — The status of the limit switch signal transferred from the
transducer block
18 6018 6118 UPDATE_EVT — — Shows the contents of an update event (a change to the
setpoint) upon occurrence.
19 6019 6119 BLOCK_ALM — — Shows the contents of a block alarm upon occurrence.
20 6020 6120 ALARM_SUM 0 AUTO Indicates the current alarm statuses.
21 6021 6121 ACK_OPTION 0xffff (Unack) AUTO Selects whether alarms associated with the block will be
automatically acknowledged.
22 6022 6122 DISC_PRI 0 AUTO Sets the alarm priority level.
23 6023 6123 DISC_LIM 0 AUTO Indicates the status of the input for the discrete alarm.
24 6024 6124 DISC_ALM — — Indicates the status related to the discrete alarm.
