6.11 I/O No. Allocation Method
The allocation of I/O No. is to give the address to the I/O terminal of each module in order to read the data from
input module and print the data to output module when performing the operation.
For I/O No. allocation, base no., slot position, module type for setup and parameter setting etc. are related. XGK
provides 2 types such as fixed and variable.
6.11.1 Fixed I/O No. Allocation
By selecting “Assign fixed points to I/O slot” from basic parameter, 64 points shall be allocated to each slot
regardless of setup module. In this case, I/O parameter shall be applied only to judge whether the module
type installed in the system corresponds, but not applied to point allocation.
For example of point allocation, please refer to “2.3 Basic System”.
6.11.2 Variable I/O No. Allocation
By releasing “Assign fixed points to I/O slot” from basic parameter, the variable type that the point allocation is
changed per slot shall be set.
If setting I/O parameter, the point related to the setting module shall be given to the assigned slot. For the next
slot, the number following I/O no. occupied by the previous slot shall be allocated.
For example of point allocation, please refer to “2.3 Basic System”.
