PLC register addresses(500-Words)?

Is there a multipoint
control unit among theconnected devices?

YES

Fixed Address Method

Flexible Address Method

Multi Address Method

Flagless Method

Minimum initial setup. 500-Words
are occupied in PLC register.
Setting changes after initial setup
are impossible.

Medium level of changes for initialsetup.Consecutive registeraddresses are not required,
so a minimum of addresses canbe used (fast response). One item
can be set at a time.

Basically the same as the Flexible
Address method, but Block
communication is possible, whichallows the fastest response when
multipoint controllers are connected.
One item can be set at a time.

Maximum workload for initial setup,
however, address changes, etc.
after initial setup are easy because
no flag is used, and setting changes
from both controllers (to PLC) andPLC (to controllers) are possible.

Multi Address Method

If consecutive PLC register addresses can besecured, this method is made easy by using thedefault values of the SIF-600, without programming.

PLC register addresses do not need to be set
consecutively. As data items can be randomly set,
the space occupied by register addresses is greatly
reduced, compared to Fixed Address Method.

PLC register addresses do not need to be set
consecutively. Block (multiple) data communication
is available and most suitable for multiple dataexchange with a multipoint controller.
