Error common
information
• This register stores common information corresponding to the error
code stored in SD0.
• The following five 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 5).)
1) Module No.
*1 For the multiple CPU system using the Basic model QCPU, High
Performance model QCPU, Process CPU, and Universal model
QCPU, the slot No. or CPU No. is stored according to an error.
(For details, refer to each error code.)
CPU No. 1: 1, CPU No. 2: 2, CPU No. 3: 3, CPU No. 4: 4
*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
