period settings
Period type
- High-speed link service is used to send and receive data by user
defined parameters when the execution of PLC program is ended.
Thus, if the scan time of PLC program is as short as
㎳
or less,
the communication data will be increased since the
communication module sends data at the end of every scan, which
will cause decreased efficiency of the whole communication
system. In order to prevent this, the communication is controlled
by the specified communication period whose setting range is 20
㎳
~ 10sec, which will be automatically set to default of 200
㎳
if
not specified.
- The communication period will be applied for Send blocks.
- The communication period will be applied identically to all the Send
blocks included in the same High-speed link parameter number.
