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.

Start byte

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.).
