Figure 4.1 Overview of Physical Block
Physical block parameters contain the characteristic
data of a device such as the tag number, device name,
version, and serial number, etc. For a list of the
parameters in the AXF blocks, see “Chapter 9”. The
following is a list of basic parameters of the physical
block.
TARGET_MODE:
Indicates the physical block mode: Out of Service (O/
S) or AUTO. In Out of Service mode, the block does
not operate. Under normal circumstances, this is set to
AUTO mode.
TAG_DESC:
Tag description parameter (32chars.)
DESCRIPTOR:
User-definable text (a string) to describe the device
application (32chars.)
WRITE_LOCKING:
Locks the software in read-only mode.

Figure 4.2 Overview of AI Block
The AI block contains all the data for final processing
of measured values prior to transmission to the master
system. For a list of the parameters in the AXF blocks,
see “Chapter 9”. The following describes the basic
parameters of the AI block.
