User-set Allocations Section 4-4
d) The start bit for node addresses can be bit 00 or bit 08. If it is bit
08 however, 2 or more bytes cannot be allocated as shown below.
e) Multiple masters cannot share the same slave.
You can determine whether there are duplicate node addresses in the
I/O allocations (scan lists) that were created simply by conducting a
master parameter file duplicate check from the Configurator.
f) Be sure to use user-set allocations and operate with the scan list
enabled if multiple masters are connected to a single network. A
Bus OFF errors will occur if multiple fixed allocations masters op-
erating with the scan list disabled are present on a single network.
g) Multiple Master Units can be included in a single PC as shown be-
low using user-set allocations (16 Units max.).
Note Use Configurator Ver. 2.10 or later for the CJ1W-DRM21.
