Note	1. The words corresponding to the node address of the Master Unit are not actually used by the
		Master Unit, so they can be used by other Slaves. The actual node address of the Master Unit,
		however, cannot be the same as the node address of another Slave.
Note	2. When Slaves made by other companies are used that are for either output only or input only,
		both the output area and the input area may be used depending on the status information.

Therefore, be sure to check the specifications of the Slave before using any word allocated to a Slave.

HI/O Allocations and Errors

A setup error may occur when the scan list is disabled or a verification error may occur when the scan list is enabled if I/O allocations are not correct.

DSetup Error: I/O Area Overlap

A setup error (I/O Area Overlap) will occur and it will not be possible to start CompoBus/D communica- tions if the same word is used by more than one Slave connected to a SYSMAC Master Unit. This error will occur only when the scan list is disabled.

To eliminate the I/O area overlap and clear this error, change the node address setting on one of the Slaves and restart the Master Unit by turning ON the power again or restarting.

DSetup Error: I/O Area Range Violation

A setup error (I/O Area Range Violation) will occur and it will not be possible to start CompoBus/D com- munications if node addresses are set at values that exceed the specified range, or if Slaves that use multiple words are using more words than are specified in the I/O area. This error will occur only when the scan list is disabled.

To eliminate the above problems and clear this error, change the node address setting on the Slaves and restart the Master Unit by turning ON the power again or restarting.
