Chapter6 Communication Mode
6 - 19
Reference : Refresh of Input / Output data
Since the I/O processing system of EH-150 is refreshment processing, the data of X and Y is usually refreshed at a
scanning end. (In the case of the above program, it becomes a scanning end that X2113 and WX212 change.)
EH-150 is supporting the command refreshed for I/O data (FUN 80 – FUN 82) also in the middle of scan. Please
describe, just before referring to X and WX if needed.
