EPC7-4B : Set the Command Module’s 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 address from 2 through 101.
See Appendix A, "Terms and Definitions," for more information on the
servant area.
