1.3 SETTING SLAVE FUNCTIONS
To use the DeviceNet slave functions, you must set the MAC-ID,
baud rate and address assignments.
The "MAC-ID (Media Access Control ID)" is the ID used for
identifying on the network the DeviceNet communications board that
is currently mounted on the CNC.
This MAC-ID is set to a value within the range 0 to 63, and must not
duplicate the ID of another node on the network. The "baud rate" is
the network's communicating speed. Set the same value as the baud
rate currently set for communications on the network. (Refer to the
baud rate setting of the master device currently used on the network.)
"Address assignment" refers to setting of the DI/DO sizes when I/O of
the DI/DO signals is performed and to setting of the PMC addresses
(addresses of R areas) that are used.
