(c) Precautions
• When SM776 is on, local device data are read out when a subroutine program is called, and the data are
saved after execution of the RET instruction.
Because of this, the scan time is increased if one subroutine program is executed with SM776 set to on.
• The on/off status of SM776 is set for each CPU module.
It cannot be set for each file.
• If the on/off status of SM776 is changed during sequence program execution, control is implemented
according to the information after the change.
Remark
For details of SM776, refer to CHAPTER 12.
