4) Parameter Setting
a) 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.”
b) Timeout Output (Clear/Hold)
The data that is output when the CPU Module changes from a running status to a
stopped status can be specified. Either of the following settings is possible.
• Clear: “0” is output.
• Hold: The data just before entering stopped status is output.
c) Mode
The number of data output from the Register Output Module can be set.
Either 8CH or 16CH can be specified.
The MEMOSOFT is set by default to “16CH.”
d) Cycle
The cycle to read the output data can be set.
Any of five cycles listed in the following table can be set.
The MEMOSOFT is set by default to 32/64 ms.
When a specified value is set for the cycle, the values of select Timing T1, T2, T3,
and T4 are set according to the set cycle.
The following table shows the values of Select Timing when the cycle is set to a
specified value.
