Appendix 1. Function Block Parameters
NOTE: Throughout the following tables, the Write column shows the modes in which the respective
parameters can be written. The legends of the entries are as follows:
O/S: Can be written when the corresponding block is in O/S mode.
Man: Can be written when the corresponding block is in Man mode.
Auto: Can be written when the corresponding block is in Auto, Man, or O/S mode.
— : Can be written in no mode of the corresponding block.
Blank: Can be written in all modes of the corresponding block.

(factory setting)
Write Description
0 1000 Block Header Block Tag
=O/S
Information about this block, including the block
tag, DD revision, execution time
1 1001 ST_REV 0 — Incremented when a change is made to the
parameter settings for the resource block to
indicate the revision level of the settings, and
used to see whether or not there is a change in
parameter settings.
2 1002 TAG_DESC Null Universal parameter storing the description of the
tag
3 1003 STRATEGY 1 Universal parameter used by an upper-level
system to classify the function blocks.
4 1004 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
specic area of the plant.
5 1005 MODE_BLK O/S Auto Universal parameter that indicates the block
operation conditions and is composed of actual
mode, target mode, permitted modes, and normal
mode.
6 1006 BLOCK_ERR — — Universal parameter indicating the hardware and
software error statuses related to the block itself
7 1007 RS_STATE — — Indicates the statuses of resource in the YVP110.
8 1008 TEST_RW Null Parameter used to test read and write access to
the YVP110

11 1011 DEV_TYPE — ID number of device; 1 or 7 (/EE) is assigned to
the YVP110.
12 1012 DEV_REV — Revision number of the YVP110
13 1013 DD_REV — Revision number of the device description (DD)
applied to this YVP110
