■Importing input (X) data
When setting "Import" for "Input Status Outside Group," the ON/OFF data can be imported from an input module and
intelligent function module which are controlled by another CPU module.
The data can be imported from the following modules mounted on the main or extension base unit.
• Input module
*1
• I/O combined module
• Intelligent function module
*1 For MELSEC iQ-R series, the areas assigned to the output portion (unused area) are not imported. The ON/OFF state is retained.
Data of an input module controlled by another CPU module and data of an intelligent function module can be read with the
following functions:
Function name
mdBdRandREx
mdBdReceiveEx
For details on functions and creating user programs, refer to the following:
MELSEC iQ-R MELSECWinCPU Module Programming Manual
■Importing output (Y) data
When setting "Import" for "Output Status Outside Group," the ON/OFF data can be imported from an output module and
intelligent function module which are controlled by another CPU module.
The data can be imported from the following modules mounted on the main or extension base unit.
*1
• Output module
*1
• I/O combined module
• Intelligent function module
*1 Data cannot be imported from MELSEC-Q series modules.
Data of an input module controlled by another CPU module and data of an intelligent function module can be read with the
following functions:
Function name
mdBdRandREx
mdBdReceiveEx
For details on functions and creating user programs, refer to the following:
MELSEC iQ-R MELSECWinCPU Module Programming Manual
■Reading data from the buffer memory of an intelligent function module
Data in the buffer memory of an intelligent function module can be read with the following functions:
Function name
mdRandREx
mdReceiveEx
For details on functions and creating user programs, refer to the following:

Precautions
■Outputting data to an output module and intelligent function module
The ON/OFF data cannot be output to non-controlled modules.
If the output status of the non-controlled module is turned ON/OFF by a user program, the output status of the
MELSECWinCPU module is changed, however not for the non-controlled module.
■Writing data to the buffer memory of an intelligent function module
Data cannot be written to the buffer memory of an intelligent function module controlled by another CPU module.
