(a) Input
On/off data of an input module are batch-input to the area for communication with the input module in the CPU
module before the start of sequence program operations.
The CPU module performs sequence program operations using the on/off data stored in the input (X) device
memory.
(b) Output
The operation results of the sequence program is output to the output (Y) device memory in the CPU module
every time program operation is performed. Then, the CPU module batch-outputs the on/off data in the output
(Y) device memory to an output module before the start of sequence program operations.
76
Before program operation, input data are collectively read out from the input modules (1), the OR processing with
the programming tool input area and remote input refresh area is executed, and then the data are stored in the
input (X) device memory.
Before program operation, data in the output (Y) device memory (2) are collectively output to the output module.
Input data in the input (X) device memory (3) are read out and the program is executed.
Output data in the output (Y) device memory (4) are read out and the program is executed.
The operation result of the program (5) are stored to the output (Y) device memory.
