Mailbox Interface
This chapter describes the fieldbus specific mailbox commands in the module. Consult the AnyBus-S
Design Guide for more information regarding mailbox functionality. Note that this interface cannot be
accessed when using the serial Configuration Interface.
Fault and Status Information
