Special Register List (Continued)
• This register stores the error code where the error reset is
performed.
• A value stored in this register is incremented by 1 whenever the
input voltage falls to or below 85% (AC power)/65% (DC power)
of the rating during operation of the CPU module. The value is
stored in BIN.
• The counter repeats increment and decrement of the value;
0→32767→-32768→0.
• This register stores the lowest I/O number of the module with a
blown fuse.
• This register stores the lowest I/O number of the module where
the I/O module verify error has occurred.
96 : 9600bps, 192 : 19.2kbps, 384 : 38.4kbps
576 : 57.6kbps, 1152 : 115.2kbps
The data of the RS-232 connection is used for any other
connection. (When an external device is not connected, the
default is 1152).
1: This applies to Universal model QCPUs except for the Built-in Ethernet port
QCPU.
