Function
Contains the starting bank number of EM trace memory or EM file
memory. All EM banks from this starting bank to the last bank in
the EM Area are formatted for use as file memory or trace mem-
ory. If EM Area banks are not formatted to file memory or trace
memory, this A344 will be FFFF hex.
To convert part of the EM Area to file memory or trace memory,
select PLC - Memory Allocation - EM Memory Settings from
the CX-Programmer, and then select File Memory or Trace Mem-
ory.
When A344 is not FFFF hex and this flag in ON, the banks of the
EM Area from the bank given in A344.00 to A344.07 to the end of
the EM Area are formatted to trace memory.
When A344 is not FFFF hex and this flag in ON, the banks of the
EM Area from the bank given in A344.00 to A344.07 to the end of
the EM Area are formatted to file memory.

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 executed, 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.
A346 contains the rightmost 4-digits and A347 contains the left-
most 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 the CX-Programmer, with the
DATE(735) instruction, or with a FINS command (CLOCK WRITE,
0702).
