Set Up the DeviceNet I/O Connections
Set up the serial link before setting up the connection. To set up communication
with the network configuration tool, you typically need to know the connection
input and output sizes.
See Set Up the Serial Link on page 19 for instructions on setting up the serial
connection and receive and transmit sizes.
If you are using a network configuration tool with some type of scanner or
scanning software, the scanner must be directed to set up the connections. This
often requires some device information, such as input and output sizes. The input
and output sizes are computed from the transmit and receive sizes. These sizes are
defined in the parameter object of the device. The transmit size of the poll
connection is computed by adding 2 to the transmit buffer size on the 1799-DASCII
module. The transmit size for the change-of-state and cyclic connections are set to
0, because these connections do not initiate a transmission on the serial link. The
receive size of all three connections is computed by adding the number of option
bytes to the receive buffer size.
