information information
Explanation
• This register stores common information corresponding to
the error code stored in SD0.
• The following ten types of information are stored here:
• The error common information type can be determined by
"common information category code" stored in SD4.
(Values stored in "common information category code"
correspond to the following 1) to 8).)
1) Module No.

*1 For a multiple CPU system, the module No. or CPU No.
(CPU No.1: 1, CPU No.2: 2, CPU No.3: 3, CPU No.4: 4)
is stored according to an error. (For details, refer to
each error code.)
*2 If a fuse has been blown or an I/O module verify error
occurs in a module on the MELSECNET/H remote I/O
station, the network No. is stored in the upper 8 bits and
the station No. is stored in the lower 8 bits. To
determine a fuse-blown module or a module where an
I/O module verify error occurs, check the I/O No.
*3 If an instruction is executed from the Basic model
QCPU to a module mounted on the slot where no
module should be mounted, "255" is stored in SD5.
*4 The definitions of the base No., slot No., and block No.
are as follows:
[Base No.]
This number indicates a base unit on which the CPU module
is mounted.
Base No. Definition
0 Indicates the main base unit where a CPU module
is mounted.
1 to 7 Indicates the extension base unit. The stage number
setting made by the stage number setting connector
on the extension base unit is the base No.
When stage number setting is extension 1: Base No. = 1
When stage number setting is extension 7: Base No. = 7
[Slot No.]
This number is used to identify the slot of each base unit and
a module mounted on the slot.
The "0" I/O slot (slot on the right of the CPU slot) on the main
base unit is defined as "Slot No. = 0". The slot Nos. are
assigned in sequence numbers in order of the main base unit
and then the first extension base unit to 7th extension base
unit. When the number of slots on base units has been set in
the I/O Assignment tab of "PLC Parameter", the slot Nos. are
assigned by the number of set slots.
[Block No.]
Block No. Definition
0
Indicates the number of main block where a CPU
module is mounted.
1 to 3 Indicates the main block where a CPU module is
mounted.
Extension block 1: Block No. = 1
Extension block 2: Block No. = 2
Extension block 3: Block No. = 3
