6.11.3 Module Reservation Function
This function is used for the variable I/O number allocation method to reserve modules to be mounted. If this
function is used, the program modification is not necessary to change the I/O number.
It can be set in the I/O Parameters window of XG5000.
6.12 Program Modification during Operation
It is available to modify program or some parameter without stopping the control operation during PLC operation.
For further information, please refer to XG5000 user’s manual.
The items available to modify during operation are as below.
•
Program modification
•
Communication parameter modification
Notes
1) If a module greater than 16-point is mounted on without reservation, the I/O number will become
different and an abnormal operation will occur.
2) Only reserved points are available although larger point modules are mounted. The remainder are
ignored.
3) Program modification is not necessary because all slots are assigned as 64points in Fixed Allocation.
