information
• Stores common information corresponding to the error code (SD0).
• There are three types of information that are stored.
• The type of error common information can be identified by SD4 "common
information category code". (The values of "common information category
code" stored in SD4 correspond to items 1) to 3) below.)
1) Module No.
*1 The slot number is defined as follows:
[Slot No.]
This value identifies the connected module.
The module connected to the right of the head module is considered "Slot
No. = 0", and the rest of the modules are numbered incrementally in series.
*2 If the slot number does not exist in the module No., FFH is stored.
*3 When FFFFH is stored in SD6 (I/O No.), it means that the I/O No. could not
be identified in I/O Assignment of PLC Parameter. In this case, the error
location is identified in SD5.
2) File name/drive name
3) Time (Set value)
