Common error
information
• Common information corresponding to the error code (SD0) is stored.
• The following three types of information are stored.
• Common error information type can be determined by "Common information category
code" in SD4.
(The value of the Common information category code stored in SD4 corresponds to 1),
3), and 7) below.)
1) Module No.
*1 For multiple CPU systems, the slot No. or CPU No. is stored, depending on the
error.
(Regarding which number is stored, refer to each error code.)
No. 1 CPU: 1, No. 2 CPU: 2, No. 3 CPU: 3, No. 4 CPU: 4
*2 Definition of the base No. and slot No.
<Base No.>
The value to identify the base unit mounted on the C Controller module.
The definition of the base No. is shown in the following table.
<Slot No.>
This value to identify the slot of each base unit and the module inserted in the slot.
*3 When FFFF
H is stored in SD6 (I/O No.), the error location is identified by SD5
because I/O numbers such as duplicated I/O numbers cannot be identified when
using I/O assignment of C Controller setting utility.

BaseNo.
Indicates the main base unit which a CPU module is mounted.
Indicates an extension base unit.
The stage number setting by a base number setting connector
of extension base unit turn to be Base No.
When a stage number setting is the first stage of extension
module: Base No. = 1
When a stage number setting is the seventh stage of
extension module: Base No. = 7
Definition
• I/O slot 0 (the right side of slot for the CPU slot) of the main base unit is the slot
of "Slot No. = 0".
• The slot No. order is the main base unit, the extension base unit numbers 1 to 7
in that order, and a serial number is assigned to each slot of each base unit.
• If I/O assignment of C Controller setting utility is used to set the number of slots
in the base unit, slot numbers are assigned for the set number of slots.
