The following services are implemented for the DeviceNet Object.
Assembly Object
CLASS CODE 0x0004
The following class attributes are supported for the Assembly Object:
I/O Modules and “Byte-wise” I/O Assemblies
When “Byte-Wise” I/O Assemblies are chosen, each I/O Module on an MDSA back-plane
generates one byte of data in the assemblies. The “byte-wise position” within the assembly is
dependent upon the I/O module position on the back-plane. The I/O module that is
physically closest to the DeviceNet Module appears at the lowest “byte-wise position” within
each assembly.
The following table lists the “Output” or “Consumed” byte-wise data for each I/O Module
