Precautions when Using the CX-Programmer

144

Specifying Operand Addresses Not Supported by the CQM1H

The program cannot be transferred from the CX-Programmer to the Customizable Counter Unit if the following
operand values are set for STIM or ACC.
STIM: C2 = 001 or C3 = 001 to 003 when C1 = 011 or 012
ACC: M = 004 to 007
Either input the instructions from the Programming Console or use dummy operands and then correct them from
the Programming Console after transferring the program to the Customizable Counter Unit.

Note The program can be read from the Customizable Counter Unit to the CX-Programmer even if the above

operand values are set.

Setting the Unit Setup Area (DM 6600 to DM 6655)

To read or edit the Unit Setup Area, specify the DM Area addresses directly from the Memory Window. The
Memory Window can be accessed by selecting PLC – Edit – Memory from the Main Menu.

Reading the Error Log

To read the error log, specify the DM Area addresses (DM 6145 to DM 6199) directly from the Memory Window.

Checking the Ladder Program Size

The ladder program size, EM Area settings, and similar information cannot be checked from the CX-Programmer
because the “Device Type” is set to the CQM1H. To check the ladder program size, select View – Cross-Reference
Report and then subtract the unused UM size from the total UM size to determine the amount of UM that has been
used. The program cannot be transferred to the Customizable Counter Unit if the UM Area size is exceeded.

Monitoring the Cycle Time

The cycle time displayed when PLC – Edit – Cycle Time is selected will be 10 times the actual cycle time of the
Customizable Counter Unit. For example, if the CX-Programmer displays 10 ms, the cycle time is 1 ms.

Startup Operating Mode

If the User Setup Area is set to startup in the mode specified on the Programming Console (i.e., bits 00 to 07 of
allocated DM Area word m are set to 01 Hex) and the CX-Programmer is connected to the peripheral port on the
Customizable Counter Unit with an CS1W-CN226/626 or CS1W-CN118 + XW2Z-200/500S-CV Cable, the Custo-
mizable Counter Unit will start in RUN mode.

Change from Programming Console Cable to CX-Programmer Cable

If the cable connecting the Programming Console is removed and the cable connecting the CX-Programmer is
connected within 2 seconds, the CX-Programmer will not go online.

PLC Information Display

The PLC information display cannot be used. (The information for the CQM1H will be displayed.)

Symbol Names

Some of the CQM1H global symbols and memory area settings registered in advance on the CX-Programmer are
not correct for the Customizable Counter Unit. These are listed in the following tables.

The following symbols cannot be used when inputting instruction operands.
