Appendix A
Precautions when Using the CX-Programmer
This appendix describes precautions and restrictions encountered when using the CX-Programmer with the Cus-
tomizable Counter Unit. When using the CX-Programmer with the Customizable Counter Unit, set the Device
type/CPU model to “CQM1H-CPU61.”
Restrictions
Due to functional differences, the following CX-Programmer functions cannot be used with the Customizable
Counter Unit (because it is set at a “CQM1H-CPU61”). Do not attempt to use these functions.
Function Operation
Editing, transferring, or comparing PC Setup PLC – Edit – PC Setup (including PLC and Transfer for
Transfer/Verify)
Reading the error log PLC – Edit – Error log – Error Log Tab
Reading setting the clock PLC – Edit – Clock
Reading/setting forced-status for PC memory PLC – Edit – Memory – Address Tab – Forced Status
Setting or executing data traces PLC – Data Trace
Displaying PC information while online PLC – Edit – Information
Correct information will not be obtained and data will not be written if the above operations are performed.
Caution A write error will occur if an attempt is made to transfer the PC Setup to the Customizable Counter
Unit. When transferring the program to the Customizable Counter Unit, remove the checkmark
from PC Setup before executing the transfer. An error will occur if this checkmark is not removed.
Set the Unit Setup Area using normal DM Area editing functions.
Always following the precautions given later in this appendix when using any of the following functions.
• Reading the error log in the Customizable Counter Unit
• Setting the Unit Setup Area (DM 6600 to DM 6655)
• Monitoring the cycle time of the Customizable Counter Unit
Precautions
Observe the following precautions when using the CX-Programmer connected to the Customizable Counter Unit.
Setting the Device Type and CPU Model
In the Change PLC Dialog Box, set the Device Type to “CQM1H,” the CPU Model to “CPU61,” and the Network
Type to “Toolbus.”
Using Instructions Not Supported by the CQM1H
The TMHH and MOVL instructions are not supported by the CQM1H. Use the following method to input them.
1. Set bits 08 to 11 of DM 6600 in the User Setup Area to 1 Hex to enable user settings for expansion instructions.
2. Double-click “Expansion Instructions” in the project workspace in CX-Programmer.
3. In the Expansion Instruction Mapping Dialog Box, select PMCR instead of TMHH and 7SEG instead of MOVL
and allocate them in the setting table.
4. Use the above instructions (PMCR and 7SEG ) in programming for TMHH and MOVL. (Use DIFU to create an
upwardly differentiated version of 7SEG for MOVL; @ cannot be used for 7SEG.)
5. Select PLC – Transfer – To PLC, check Programs and Expansion Instructions, and then click the OK Button.
