Restrictions on Duplication
The following restrictions are applied to the instance numbers.
• The input instance number and output instance number must not be duplicated at the same connection number.
• For Scanner, duplication of input and output instance numbers is permitted if the connection number differs.
• For Adaptor, duplication of input and output instance numbers is not permitted even if the connection number
differs.
An error will occur when saving the settings if the restrictions above are not observed.

remote station is replaced with the Scanner input setting.
<Examples>
If the Adaptor setting at remote station is: Input instance number 100 and Size 100, Output instance number
then, the Scanner setting must be: Input instance number 101 and Size 50, Output instance number 100 and
