(3) Service Scan: Normal/High-speed
Two types of service scans are available: normal and high-speed . A service scan
is recommended when using the high-speed segment function. The I/O module is
activated before the ladder decoding of the high-speed segments. The I/Os that are
processed in synchronization with the high-speed scan are called
High-speed Seg-
ment I/Os . The MEMOSOFT is set by default to “ NORMAL .”
d) Input Signal Status
Error signals are generated by the Analog Input Module when an input signal
exceeds the input signal range.
