16.2.3 I/O Condition
I/O condition means the function to forcibly record a user-present value into a specific device when meeting conditions that are entered

is 1’ constitutes the condition and ‘set all the values of device %MX0 ~ %MX100 as 1’is ‘recording the user-preset value forcibly.’
XG-SIM provides I/O condition function to eliminate discomfort that to test a user-created PLC program, a user should periodically
change device value by changing the monitor current value of XG5000 or should create another PLC program to test PLC program. In
