Up to two connections can be selected from the four connection types, but only
one connection of each type can be made. For example, one polled connection
and 1 COS connection can be made, but not two polled connections. Both
polled and COS/Cyclic allow both inputs and outputs (read and write) in a
single connection.
A polled connection that uses both inputs and outputs can have 16 bytes of input
data and 16 bytes of output data. If you add another connection, you can have 16
additional bytes of data.
If you use the polled connection and then add a COS/Cyclic connection, the
output is unavailable. The maximum data configuration is shown below.
