Replacing the C200HW-NC
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 differences are
explained below. For more details on the differences to the ladder program, refer to Sections 4 and 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.
• Operating Memory Area
Unit numbers 0 to 9: 100 + (unit number × 10) → 2000 + (unit number × 10)
Unit numbers A to F: 400 + (unit number × 10) → 2000 + (unit number × 10)
• DM Area
DM 1000 + (unit number × 100) → D20000 + (unit number × 100)
Settings Exchanged between the Operating Memory Area and Operation
Data Area
• The following data has been moved from the operating memory area to the operating data area: positioning
sequences, output codes, present positions.
• The following data has been moved from the operating data area to the operating memory area: monitoring
information for I/O signals, error codes.
Data Conversion for Operating Data Area
• The format has been changed from BCD to binary.
• The following data has been changed to a 1-word configuration: positioning sequences, output codes, teaching
addresses.
• In addition to conversion to binary format, area designations have been added to the following data used for data
transfer: number of transfer (read or write) words, transfer (write) destination address, transfer (write) source
word, transfer (read) destination word, transfer (read) source address.
• The acceleration and deceleration times used in direct operation and origin return were specified by number, but
are now time settings.
• The speed designations used in direct operation and origin return consisted of one word of data containing a
multiplication factor, but now consist of two words of binary data without a multiplication factor.
Changes in PCU Addresses
• At data transfer, PCU internal addresses were specified in decimal but are now specified in hexadecimal.
• With the change to hexadecimal format, although the beginning address for axis parameters and the beginning
addresses for the operating data of each of the axes are the same, addresses after that have changed.
IOWR Instruction
Previously, even if the IOWR instruction was used more than once in the ladder program, all the data transfer
operations were completed within one scan. With CS1-series PCUs, however, it may take several scans before all
the data is transferred. When executing the IOWR instruction with CS1-series PCs, two words are used to specify
the destination unit number and the number of transfer words. For details, refer to 5-4 Writing Data with IOWR.
STOP Bit
Previously, axis operation was possible even with the STOP Bit turned ON, but with CS1-series PCUs, it is not.
Also, when the STOP Bit and FORCED INTERRUPT Bit were turned ON simultaneously, the FORCED INTER-
RUPT Bit would take priority, but with CS1-series PCUs, the STOP Bit is given priority. For details, refer to 9-5
Deceleration Stop.
Releasing Pulse Output Prohibition
Previously, it was not possible to clear only error codes to 0, but with CS1-series PCUs, it is possible to clear error
codes to 0 by turning ON the ERROR RESET/RELEASE PROHIBIT Bit.
