On the MC Unit, the custom I/O area can be treated as I/O variables in the
motion program.
When transfer direction is [MC Unit _ CPU]: Output variable
When transfer direction is [CPU _ MC Unit]: Input variable
Area Input variable
General I/O A IW0B00
General I/O B IW0BA0
General I/O C IW0C40
General I/O D IW0CE0
General I/O E IW0D80
General I/O F IW0E20
General I/O G IW0EC0
General I/O H IW0F60
Name
Port_A Area type CPU Unit area type for General I/O A:
0: Not used (no transfer).
1: CIO
2: WR
3: DM
4: EM (fixed at bank 0)
5 and higher: Reserved for system.
Port_A Direction Transfer direction for General I/O A:
0: MC Unit to CPU Unit
1: CPU Unit to MC Unit
Port_A First Address CPU Unit first address for general I/O A:
0000H-(Upper limit varies depending on Port_A Area type.)
• General I/O area allocation is performed using [PORT_* Number of trans-
ferred words], [PORT_* Area type], [PORT_* Direction], and [PORT_*
First address].
• The destination of allocation in the MC Unit is:
When [PORT_* Direction] is 0 (MC Unit to CPU): Output variable
When [PORT_*Direction] is 1 (CPU to MC Unit): Input variable.
• The above data can be used only for PC21 Bus Initialization. It will be
ignored if it is changed after the power is already ON.
(1) Make sure that values of the data are appropriate for operations.
(2) Make sure to confirm the safety of devices prior to changing the allocation
areas.
CS-series CPU Units have the following three operating modes:
1. RUN Mode
Programs can be executed normally.
2. MONITOR Mode
Programs can be executed normally. Data saved in the memory can be
modified.
3. PROGRAM mode
Programs cannot be executed. Programming and debugging are possible.
