  • Page 41: Operations Arising When The Out, Set/Rst, And Pls/Plf Instructions Of The Same Device Are Used

    Operations Arising when the OUT, SET/RST, and PLS/PLF Instructions of the Same Device are Used If two or more OUT, SET/RST, and PLS/PLF instructions are executed using the same device during one scan, they operate as described in this section. For OUT instructions of the same device More than one OUT instruction of the same device must not be issued during one scan.
  • Page 42 If SET/RST instructions of the same device are used ■For SET instructions The SET instruction turns on the specified device if the execution command is on, and causes no operation if it is off. Thus, if two or more SET instructions of the same device are executed during one scan, the specified device turns on even if one execution command is on.
  • Page 43 If PLS instructions of the same device are used The PLS instruction turns on the specified device when the execution command specifies an off-to-on change. The specified device is turned off unless the execution command specifies an off-to-on change (i.e. off to off, on to on, on to off). Thus, if two or more PLS instructions of the same device are issued during one scan, the specified device is turned on when the execution command of each PLS instruction specifies an off-to-on change.
  • Page 44 • If the off-to-on changes of X0 and X1 are at the same timing PLS M0 PLS M0 PLS M0 (1) Since X0 turns on, M0 turns on. (2) Since X1 turns on, M0 remains on. (3) Since X0 is other than turning on, M0 turns off. (4) Since X1 is other than turning on, M0 remains off.
  • Page 45 If PLF instructions of the same device are used The PLF instruction turns on the specified device when the execution command specifies an off-to-on change. The specified device is turned off unless the execution command specifies an on-to-off change (i.e. off to off, off to on, on to on). Thus, if two or more PLF instructions of the same device are issued during one scan, the specified device is turned on when the execution command of each PLF instruction specifies an on-to-off change.
