(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 SM 776 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.
