V743-2B : Setting

the Command

Module Servant

Area

Notice the following when setting the Command Module servant area.

• For the Command Module to be the commander of a register-based

module, the register-based module’s logical address must fall within

the Command Module’s servant area. The servant area of the

Command Module is determined as:

Servant area = (logical address + 1) through (logical address +

servant area switch setting)

• The logical address plus the Command Module’s servant area cannot

exceed 255. Therefore, set the servant area based on the logical

addresses of the register-based modules in your system.

For example, if the Command Module’s logical address is 1 and its

servant area switch is set to 100, the Command Module would be the

commander for all modules with logical addresses from 2 through

101.

Servant area 255 is shown.

The servant area is the decimal sum of the switches in the

closed (1) position.
