Figure 5.1 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 EJA blocks, see “APPENDIX 1.
LIST OF PARAMETERS FOR EACH BLOCK OF
THE EJA.” in Appendix 1. 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:
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 5.2 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 EJA blocks,
see “APPENDIX 1. LIST OF PARAMETERS FOR
EACH BLOCK OF THE EJA”. The following de-
scribes the basic parameters of the AI block.
