*1 The "power supply 1" indicates the redundant power supply module mounted on the POWER 1 slot of the redundant
base unit (Q38RB/68RB/Q65WRB).
*2 The "power supply 2" indicates the redundant power supply module mounted on the POWER 2 slot of the redundant
base unit (Q38RB/68RB/Q65WRB).
*3 Modules whose serial number (first five digits) is "07032" or later. In a multiple CPU system, the serial number (first five
digits) of all the CPU modules must be "07032" or later.
*4 Modules whose serial number (first five digits) is "10042" or later

Explanation
• This register counts the number of times of momentary
power failure of the power supply 1/2.
• This register monitors the status of the power supply 1/2
mounted on the redundant power main base unit (Q38RB)
and counts the number of momentary power failures. The
status of the power supply 1/2 mounted on the extension
base unit for redundant power supply system and the
redundant type extension base unit is not monitored.
• When the CPU module starts, the counter of the power
supply 1/ 2 is cleared to 0.
• If the input power to one of the redundant power supply
modules is turned off, the corresponding counter is cleared
to "0".
• The counter is incremented by one upon momentary
power failure on the power supply 1 or 2. (The counter
repeats increment and decrement of the value; 0  32767
 -32768  0. (The value is displayed within the range of
0 to 65535 in the system monitor screen of programming
tool.))
• When the main base unit is not the redundant power main
base unit (Q38RB), "0" is stored.
• In a multiple CPU system, the status is stored only to CPU
module No.1.
Explanation
The cyclic transmission status of each station is stored in the
following bit pattern. (Off: Not performed, On: Being
performed)

The numbers in the figure indicate station numbers.
(Condition)
• Only the bit of the start station number turns on.
• The status is not stored for the reserved stations and the
station numbers after the maximum station number.
Use this register as an interlock for cyclic transmission. For
details on the interlock program, refer to the following.
