PC Setup Section 1-1
Errors in the PC Setup If an incorrect PC Setup setting is accessed, a non-fatal error (error code 9B)
will be generated, the corresponding error flag (AR 2400 to AR 2402 in the
CQM1, AR 1300 to AR 1302 in the CPM1/CPM1A/SRM1) will be turned ON,
and the default setting will be used instead of the incorrect setting.
1-1-2 CQM1 PC Setup Settings
The PC Setup is broadly divided into four categories: 1) Settings related to
basic CQM1 operation and I/O processes, 2) Settings related to pulse output
functions, 3) Settings related to interrupts, and 4) Settings related to commu-
nications. This section will explain the settings according to these classifica-
tions.
The following table shows the setting in order in the DM area. For details, refer
to the page numbers shown.
