4.1.1. I/O Assemblies
Assemblies are a collection of attributes and are an integral part of the I/O
data exchange. It is the Assembly that defines what data and how much
data is exchanged between the Master and the device in an I/O type of
connection. Assemblies are grouped into two categories: Input and Output
From a device perspective, an Input Assembly is the data PRODUCED from
the device ONTO the network (or can also be viewed as data “INPUT” to the
Master FROM the device). Again, from a device perspective, an Output
Assembly is the data CONSUMED from the network INTO the device (or can
also be viewed as the data “OUTPUT” from the Master TO the device).
A selection of pre-defined Assemblies is listed in Appendix A. Once the
desired Assemblies have been configured in the device, corresponding
changes in configuration will probably be required from the Master side of
connection.
NOTE:
For I/O Connections to be established between Master and Slave devices,
the I/O data sizes for both Input/Output must match. Selection of an
Assembly in the PC device automatically sets the I/O data sizes and no
further configuration by the customer is required.
The table below references the parameters/attributes associated with I/O
Assembly configuration.
