Importing input (X) data
When "Import" is set for the input status in "I/O Setting Outside Group", the ON/OFF data from an input module or an
intelligent function module controlled by another CPU can be imported.
■
Modules from which input (X) data can be imported
Input (X) data can be imported from the following modules mounted on the main/extension base unit.
• Input module
• I/O combined module
*1
• 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.
Input (X) data can also be imported from a user program with the C Controller module dedicated functions
(CCPU_X_In_BitEx, CCPU_X_In_WordEx).
Importing output (Y) data
When "Import" is set for the output status in "I/O Setting Outside Group", the ON/OFF data from an output module or an
intelligent function module controlled by another CPU can be imported.
■
Modules from which output (Y) data can be imported
*1
Output (Y) data can be imported from the following modules mounted on the main/extension base unit.
• Output module
• I/O combined module
• Intelligent function module
*1 Data cannot be imported from MELSEC-Q series modules.
Output (Y) data can also be imported from a user program using the C Controller module dedicated functions
(CCPU_Y_In_BitEx, CCPU_Y_In_WordEx).
Output to an output module/intelligent function module
ON/OFF data cannot be output to non-controlled modules.
If the output state of the non-controlled module is turned ON/OFF by a program, the output state in the CPU module is
changed; however, the output state of the non-controlled module is not changed.
Accessing the buffer memory of an intelligent function module
■
Reading data in buffer memory
Use the following functions to read data from the buffer memory of an intelligent function module.
• C Controller module dedicated function (CCPU_FromBuf)
• MELSEC data link function (mdReceiveEx, mdRandREx)
■
Writing data to buffer memory
Use the following functions to write data to the buffer memory of an intelligent function module.
• C Controller module dedicated function (CCPU_ToBuf)
• MELSEC data link function (mdSendEx, mdRandWEx)
