Series 275 Convectron Module with DeviceNet
Instruction Manual - 275502 25
4 Operation
4.2.4 Data Rate (Baud Rate) Switches
The Baud Rate switch must be set according to the length of the cable between the DeviceNet
controller and the Mini-Convectron Module. See Table 4-4.
The maximum number of devices on a network is 64.
Table 4-4 Baud Rate Switch Settings
Maximum Cable Length Baud Rate Setting
500 meters 125 K
250 meters 250 K
100 meters 500 K
4.2.5 MAC ID Address Switches
Use the address switches to set the media access control identifier (MAC ID), which the network
master uses to address the module. When the device powers up or is reset by the network, the
device firmware will read the address switch settings.
Specific address values range from 0 to 63.
•
Set the switch labeled “MSD,” to a value of 0 to 6 for the most significant (first) digit.
•
Set the switch labeled “LSD,” to a value of 0 to 9 for the least significant (second) digit.
If a valid address between 0 and 63 is set, and it differs from the current address stored in
non-volatile RAM (NVRAM), the new address will be saved in memory. If the data rate switch is set to
the PGM setting, the firmware will use the data rate that is stored in NVRAM.
Upon connection to the DeviceNet network, the module requests a duplicate address check.
•
If another device on the network has the same address as the module, the module will not join the
network.
•
If the address is unique, the module will join the network and the net status indicator will blink
green until a connection to the master node is established.
