Data Conversion
Ladder Programming
Converting parameters and operating data to binary format has resulted in changes in the bits and addresses
used to exchange information commands and data between the ladder program and the PCU. The main differ-
ences are explained below. For more details on the differences to the ladder program, refer to
SECTION 4 and
SECTION 5 .
Changes in Operating Memory Area and DM Area Allocations
The addresses of the operating memory area and the DM Area words differs in the way shown below.

Previous data Details
Positioning sequences With CS-series PCUs, in addition to
changing the format for position data to
binary, a flag (the position designation)
has been added to the positioning
sequences that indicates whether the
position data is absolute or relative. For
this reason, check the position designa-
tion (i.e., whether it is absolute or relative)
for the position data in the previous for-
mat, and reflect this in the position desig-
nation in the (new) positioning sequence.
For example, if positioning sequence 0
uses X-axis position number 0, and this
position data is for relative positioning, set
the X-axis position designation for posi-
tioning sequence 0 to 1.
The total number of words of data is the
same.
Speeds Convert the 1-word settings containing
multiplication factors to 2–word,
unsigned, 32-bit binary settings (unit:
pps).
The total number of words of data will be
twice the number in the previous format.
Positions Convert to signed 32-bit binary data. In
the new format, the position designation
(relative or absolute) is set in the position-
ing sequences.
With CS-series PCUs, there is no distinc-
tion made between relative or absolute in
the position data itself. This distinction is
made in the positioning sequence.
The total number of words of data is the
same.
Acceleration times Convert to unsigned 32-bit binary data.
The total number of words of data is the
same.
Deceleration times
Dwell times Convert to unsigned 16-bit binary data.
The total number of words of data is the
same.
Zones Convert to signed 32-bit binary data.
The total number of words of data is the
same.
