SYSMAC and SYSMAC-CPT Support Software
Refer to 3-4-10 Programming Device Connections for details on connecting a personal computer to the
CPM2C.
Limitations and Precautions
When programming a CPM2C PC with the SSS, set the PC model to "CQM1." There are some software limita-
tions because of differences between the CPM2C and CQM1 CPUs.
CQM1
Program Input and Program Check
CQM1 data areas are larger than the corresponding CPM2C data areas, so the data area addresses that don't
actually exist in the CPM2C or instructions not supported by the CPM2C can be input and won't be detected in
the program check. Be sure that the word and bit addresses are within the specified ranges and that all instruc-
tions are supported.
If a program contains a data area address that exceeds the range of a CPM2C data area, a memory error will
be generated when the program is executed and the Memory Area Specification Error Flag (AR 1308) will be
turned ON.
Data area
Input words IR 000 to IR 011
Output words IR 100 to IR 111
Work words IR 012 to IR 099
IR 112 to IR 227
SR area SR 228 to SR 255
HR area HR 00 to HR 99
AR area AR 00 to AR 27
LR area LR 00 to LR 63
Timer/Counter area TIM/CNT 000 to 511
DM area Read/write DM 0000 to DM 6143 DM 0000 to DM 1999,
Read-only DM 6144 to DM 6568 DM 6144 to DM 6599
Error Log DM 6569 to DM 6599 DM 2000 to DM 2021
PC Setup DM 6600 to DM 6655 DM 6600 to DM 6655
Since the PC model is set to "CQM1," a program that will run properly in the CQM1 will pass the program check
even if it won't run properly in the CPM2C.
Monitoring, Online Editing, and Set Values
An error message will be displayed and the values will not be accepted if a data area address that exceeds the
range of a CPM2C data area is entered for monitoring, time charts, an instruction operand, or a timer/counter
SV.
