• It is available to set by I/O module unit.
(For further information, please refer to XG5000 user’s manual.)
• As Input(I) image area stops input refresh, it keeps the value before skip setting. But, at this time, it is effective to operate the image by forced On/Off.
• Actual output of output module shall be OFF in case of skip setting but output(Q) image area is changed according to the user program operation regardless of skip setting. It is not allowed to operate output value of output module by forced On/Off after skip setting.
• The execution of skip function when using direct I/O function is same.
3) Release of Skip Function
The skip of I/O module shall be released only by the same method as setting.
• Setting release from online menu of XG5000
• Release by program
• Automatic release in case the memory backup is broken by battery voltage falling The Fault Mask shall be released even in the cases as below. Cares should be taken.
• Power Off→On
• Change of operation mode
• Program download
• Operation of reset key
• Data clear
1) When releasing a skip, if the error occurs in the corresponding module, the system may stop.
Release the skip in the state that the Fault Mask is set and check the normal operation of module before releasing the skip.

6.10 Changing Module during Operation
XGK system enables to change the module during operation. But, as the change of module during operation may occur the abnormal operation of whole system, special attention should be taken. Just follow the procedure assigned in this user’s manual.
1) Notices in Using
• Not allowed to change the base and power module.
• Some part of communication module (XGL-PMEA, XGL-DMEA) needs the network setting (Sycon used) for communication.
• In case of module change, match the joint part of the lower part of base and module correctly before inserting.
If not, it may cause the system shutdown.
2) Module Change Method
There are 2 kinds of module change method.
(1) By using XG5000 “Module Change Wizard” function.
For further information, please refer to XG5000 user’s manual.
(2) By using CPU module switch
(1) Set “Module change switch (M.XCHG)” in front of CPU module as right(ON).
(2) Remove the module. (PS LED is ON)
(3) Setup the new module. (in case of normal module setup, PS LED is OFF) (4) Check if module operates normally.
(5) Set “Module change switch (M.XCHG)” as left (OFF).
1) When changing the module, shut down the load power for safety.
2) When changing the input module, consider the setting of input image state by using the forced On/Off.
Notes
When installing the module, it may cause an abnormal operation if the lower connection is not mounted on the base completely.
Warning
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.
6-17
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.
Chapter 7 I/O Module
7.1 Notice in Selecting Module
Here describes the notices when selecting digital I/O module used for XG series.
1) For the type of digital input, there are two types such as current sink input and current source input.
For DC input module, as the wiring method of external input power varies according to such input type, consider the specification of input connecting device when selecting.
2) Max. simultaneous input point depends on the module type. It is subject to input voltage, ambient temperature. Review the specification of input module to apply before using.
3) In case that the response of high speed input is required, use Interrupt module.
But, Interrupt module is limited to use by installing only one module for one CPU module.
4) In case that open/close frequency is high or it is used for conductive load open/close, use Transistor output module or triac output module as the durability of Relay Output Module shall be reduced.
5) For output module to run the conductive (L) load, max. open/close frequency should be used by 1second On, 1 second Off.
6) For output module, in case that counter timer using DC/DC Converter as a load was used, Inrush current may flow in a certain cycle when it is ON or during operation. In this case, if average current is selected, it may cause the failure. Accordingly, if the previous load was used, it is recommended to connect resistor or inductor to the load in serial in order to reduce the impact of Inrush current or use the large module having a max. load current value.
7) For output module, fuse is not possible to change. This is to prevent of burnout of external wiring in case of short circuit of module output. This may not protect output module. In case that output module is destroyed in error mode except short circuit, fuse may not work.
