DVerification Error: Slave I/O Size Differs

A verification error (Slave I/O Size Differs) will occur and it will not be possible to start CompoBus/D communications if a Master Unit is being used with the scan list enabled and the type of I/O (input or output) or the number of I/O points registered for a Slave in the scan list does not match the actual I/O specifications of the Slave that is connected to the Master Unit. This error will occur only when the scan list is enabled.

To eliminate and clear this error, either create the scan list again or replace the Slave with the kind of Slave registered in the scan list.

Note The scan list verification is performed in byte units (8 bits). A verification error will therefore not occur if a 1-point Input Slave is used instead of an 8-point Input Slave.

Note

1.

The above example is for allocations in a CV-series PC.

Note

2.

The Master Unit is not allocated any words, so any available node address can be used as

 

 

node address 7.

Note

3.

Slaves can be allocated to the words labeled “Allocation possible” as long as the same words

 

 

are not allocated to more than one Slave.

HBasic Application Procedure
