28.14  External Input/Output Forced On/Off Function
Forced on/off timing
The following table lists the timing to reflect forced on/off registration information to the input/output devices or external 
outputs.
*1 At input/output refresh execution where input/output refresh is registered for each program, and for interrupt programs.
*2 Forced on/off is reflected only to output devices. (Since refresh to external outputs is not executed.)
*3 Forced on/off is reflected only to input devices on the standby system. (Since refresh from the CPU module to link devices is not 
executed.)
*4 Whether external outputs to the standby system are reflected or not differs depending on the standby system output setting. ( Page 
495 Reflection to external outputs of the standby system)
Input/output for which forced on/off 
can be set
Reflection timing for the input devices Reflection timing for the output devices or 
external outputs
*4
Input/output of the modules mounted on the 
base unit
• END processing (at input refresh)

input (DX) (LD, LDI, AND, ANI, OR, ORI, LDP, 
LDF, ANDP, ANDF, ORP, ORF, LDPI, LDFI, 
ANDPI, ANDFI, ORPI, ORFI)
