DeviceNet Gateway
(2) Free assignment using a configurator
By using a DeviceNet configurator, slaves can be assigned respectively to four blocks, including
output area blocks 1 and 2 and input area blocks 1 and 2, in a desired node address order within
each block. By using this free assignment function, up to 16 master units can be installed in a single
PLC.
[1] One block has a maximum of 500 channels (i.e., there are 500 output channels x 2 and 500
input channels x 2). Each item can be assigned in desired areas within the applicable range
specified below:
I/O relay: 0000~6143CH
Internal auxiliary relay: W000~W511CH
Keep relay: H000~H511CH
Data memory: D00000~D32767
Expansion data memory: E00000~E32767
[2] The blocks can be assigned in a desired order, and the assigned block areas and node
addresses in each block can also be sequenced freely.
[3] A slave having more than 16 I/O points occupies multiple channels.
[4] A slave having no more than 16 I/O points occupies either the lower byte or upper byte.
