DeviceNet Master Protocol API

DeviceNet-Master Dual-Port Memory • 43
3.3.2 Extended Status
The content of the channel specific extended status block is specific to the implementation. Depending
on the protocol, a status area may or may not be present in the dual-port memory. It is always
available in the default memory map (see section 3.2.1 of netX Dual-Port Memory Manual).
Note: Have in mind, that all offsets mentioned in this section are relative to the
beginning of the common status block, as the start offset of this block depends
on the size and location of the preceding blocks.

For the DeviceNet Master protocol implementation, the extended status area is structured as follows:
