• CPU Operating Mode (Attribute ID = 64 Hex)
Changes the CPU Unit operating mode.
The Attribute Values are as follows:
0001 Hex: PROGRAM mode; 0002 Hex: MONITOR mode;
0004 Hex: RUN mode
Note The specified code for the above operating modes are 1-word (2-byte
data, and are specified with the low byte first. For example, for PRO-
GRAM mode, the code is specified as 01 Hex followed by 00 Hex. Ac-
cordingly, the low to high bytes for the above codes are set as high
to low bytes in I/O memory, when setting the codes as data for oper-
and S of CMND(490).
• Clearing CPU Unit Errors (when Attribute ID = 65 Hex)
Clears any fatal or non-fatal errors in the CPU Unit. Sets the error clear
code to Attribute Value. The error clear codes are listed in the following
table.
Note Error clear codes are 1-word (2-byte) data, so the above codes are
specified with the low byte first. The low to high bytes for the above
codes are set as high to low bytes in I/O memory, when setting the
codes as data for operand S of CMND(490). For example, to specify
battery error 00F7 Hex, specify the error code as F7 Hex followed by
00 Hex, as shown in the following diagram.
