Function
Contains the starting bank number of EM file memory
(bank number of the first formatted bank). All EM
banks from this starting bank to the last bank in EM
are formatted for use as file memory.
To convert the EM Area for use as file memory, first set
the PLC Setup's EM File Memory Function setting to
1, set the PLC Setup's EM File Memory Starting Bank
setting, and then format the EM Area from a Program-
ming Device
The PLC Setup's EM file memory settings won't agree
with the actual settings unless the EM Area is format-
ted after the PLC Setup's EM file memory settings
have been changed. In that case, the actual settings
can be determined with this word.
Turns ON if the FB program memory contains FB
program data.
Turns ON when the comment memory contains a
program index file.
Turns ON when the comment memory contains a
comment file.
Turns ON when the comment memory contains a
symbol table file.
These words contain the 8-digit hexadecimal number
of words remaining to be transferred by FREAD(700)
or FWRIT(701). When one of these instructions is exe-
cuted, the number of words to be transferred is written
to A346 and A347.
While the data is being transferred, the value in these
words is decremented.
A326 contains the rightmost 4-digits and A347 con-
tains the leftmost 4-digits.
Check the content of these words to determine
whether or not the planned number of words have
been transferred successfully.
These words contain the CPU Unit's internal clock
data in BCD. The clock can be set from a Program-
ming Device such as a Programming Console, with the
DATE(735) instruction, or with a FINS command
(CLOCK WRITE, 0702).
