Write Description
DI1 DI2 DI3 DI4
4 6004 6104 6204 6304 ALERT_KEY 1 Universal parameter used as a key to
identify the point from which an alert is
issued; normally used by an upper-level
system to select alerts to provide to a
particular operator who covers a specific
area of the plant.
5 6005 6105 6205 6305 MODE_BLK O/S Universal parameter that indicates
the block operation conditions and is
composed of actual mode, target mode,
permitted modes, and normal mode.
6 6006 6106 6206 6306 BLOCK_ERR — — Indicates the error statuses related to the
block itself.
7 6007 6107 6207 6307 PV_D — — Indicates the primary discrete value (or
the corresponding process value) used
to execute the specified actions, and the
status of that value.
8 6008 6108 6208 6308 OUT_D — Man Indicates the output value and its status.
9 6009 6109 6209 6309 SIMULATE_D disabled — Used to determine whether to use the limit
switch signal input from the transducer
block or use the user-set value. When this
parameter is set to disable, the block uses
the actual input value and status.
10 6010 6110 6210 6310 XD_STATE 0 Index to the text describing the states
of the discrete value obtained from the
transducer, but not supported by YTA.
11 6011 6111 6211 6311 OUT_STATE 0 Index to the text describing the states of a
discrete output, but not supported by YTA.
12 6012 6112 6212 6312 GRANT_
DENY
0 Used to check whether various user
operations can be put into effective.
Before operations, in the GRANT
parameter component, set the bits
(to 1) corresponding to the intended
operations. After the operations, check
the DENY parameter component. If the
corresponding bits are not set (to 1) in
DENY, it proves that the corresponding
operation has been put into effective.
13 6013 6113 6213 6313 IO_OPTS 0 O/S Settings for the I/O processing of the
block.
14 6014 6114 6214 6314 STATUS_
OPTS
0 O/S Defines block actions depending on block
status conditions. In YTA, bit 0: Invert
alone is available.
15 6015 6115 6215 6315 CHANNEL 7/8/9/10 O/S Defines the channel number of the
hardware channel connected to the
transducer block.
16 6016 6116 6216 6316 PV_FTIME 0 second Time constant of filter for PV_D.
17 6017 6117 6217 6317 FIELD_VAL_
D
— — Status of limit switch signal obtained from
the transducer block
18 6018 6118 6218 6318 UPDATE_
EVT
— — Shows the contents of an update event
upon occurrence.
19 6019 6119 6219 6319 BLOCK_ALM — — Shows the contents of a block alarm upon
occurrence.
20 6020 6120 6220 6320 ALARM_SUM enable Shows the alarm summary (current alarm
statuses, acknowledged/unacknowledged
states, masking states) for the DI block.
21 6021 6121 6221 6321 ACK_OPTION 0xffff: unack Defines the priority of WRITE_ALM as well
as allows for notification to be disabled and
makes acknowledement unnecessary for
WRITE_ALM .
22 6022 6122 6222 6322 DISC_PRI 0 — Priority order of discrete alarm
23 6023 6123 6223 6323 DISC_LIM 0 Input status of generating a discrete alarm
24 6024 6124 6224 6324 DISC_ALM — Status of discrete alarm
