Output to output/intelligent function module
On/off data cannot be output to non-controlled modules. When turning on or off output of the output module and/or intelligent
function module controlled by other CPU modules by the program or others, the output is turned on or off within the CPU
module. However, it is not output to output/intelligent function module.
Accessing buffer memory of intelligent function module
■Reading data on buffer memory
The following instructions can be used to read data stored in the buffer memory of the intelligent function module.
• FROM instruction
• Instruction using the CPU module access device (Un\Gn)
■Writing data to buffer memory
The following instructions cannot be used to write data to the buffer memory of the intelligent function module.
• TO instruction
• Instruction using the CPU module access device (Un\Gn)
Accessing a module by using link direct devices
