0 6000 6100 BLOCK
HEADER
Block tag
= O/S
Information about this block, including the block tag, DD
revision, execution time.
1 6001 6101 ST_REV 0 — Incremented when a change is made to the parameter settings
for the DI block to indicate the revision level of the settings, and
used to see whether there is a change in parameter settings.
2 6002 6102 TAG_DESC Spaces Universal parameter storing the description of the tag.
3 6003 6103 STRATEGY 1 Universal parameter used by an upper-level system to classify
the function blocks.
4 6004 6104 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 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 BLOCK_
ERR
— — Indicates the error statuses related to the block itself.
7 6007 6107 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 OUT_D — Man Indicates the output value and its status.
9 6009 6109 SIMULATE_
D
disable — 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 XD_STATE 0 Index to the text describing the states of the discrete value
obtained from the transducer, but not supported by YVP110.
11 6011 6111 OUT_STATE 0 Index to the text describing the states of a discrete output, but
not supported by YVP110.
12 6012 6112 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 IO_OPTS 0 O/S Settings for the I/O processing of the block.
14 6014 6114 STATUS_
OPTS
0 O/S Defines block actions depending on block status conditions.
15 6015 6115 CHANNEL 2 or 3 O/S Defines the channel number of the hardware channel
connected to the transducer block. Always set 2 for the DI1
block and 3 for DI2 in a YVP110.
16 6016 6116 PV_FTIME 0 second Time constant of filter for PV_D.
17 6017 6117 FIELD_VAL_
D
— — Status of limit switch signal obtained from the transducer block.
18 6018 6118 UPDATE_
EVT
— — Shows the contents of an update event upon occurrence.
19 6019 6119 BLOCK_
ALM
— — Shows the contents of a block alarm upon occurrence.
20 6020 6120 ALARM_
SUM
enable Shows the alarm summary (current alarm statuses,
acknowledged/unacknowledged states, masking states) for
the DI block.
21 6021 6121 ACK_
OPTION
0xFFFF 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 DISC_PRI 0 — Priority order of discrete alarm.
23 6023 6123 DISC_LIM 1 Input status of generating a discrete alarm.
24 6024 6124 DISC_ALM — Status of discrete alarm.
