Explanation
• Common information corresponding to the error codes (SD0) is stored
here.
• The following five types of information are stored here:
• The error common information type can be judged by the "common
information category code" in SD4. (The values of the "common
information category code" stored in SD4 correspond to following 1) to 5).)

*1: Definitions of slot No.
<Slot No.>
Value used to identify the slot of each base unit and the module mounted
on that slot.
• The I/O slot 0 (slot on the right side of the CPU slot) of the main base
unit is defined as the slot of "Slot No. = 0".
• The slot Nos. are consecutively assigned to the slots of the base units in
order of the main base unit and extension base units 1 to 7.
• When the number of base unit slots has been set in the I/O assignment
setting of the PLC parameter dialog box, the slot Nos. are assigned for
only the number of set slots.
*2: When 0FFFFH is stored into SD6 (I/O No.), the I/O No. cannot be
identified due to overlapping I/O No., etc. in the I/O assignment setting of
the PLC parameter dialog box. Therefore, identify the error location using
SD5.
