Explanation
• Common information corresponding to the error codes (SD0)
is stored here.
• The following six types of information are stored here:
1)

*1: The storing value "255" in SD5 (Slot No.) indicates that the
slot number for a module specified by an instruction cannot
be identified. When storing the base number to SD5, store 0
(main base unit).
*2: The storing value "FFFFH" in SD6 (I/O No.) indicates that the
I/O number cannot be identified on the I/O assignment setting
tab of PLC parameter due to overlapping of I/O numbers or
that the I/O number cannot be identified from the network
number specified by an instruction. In this case, the error
location can be identified in SD5.
