3-Point-B Verification Function
This function is used to compare and verify the master data in the order that the data is read, and the data is
counted as one group.
Verify OK is output each time the data is read.
3-Point-B Verification Function
The 3-point-B function verifies three registered master data items and three read data items. Regis-
ter the data “123”, “456”, and “789” first. When the read data is “123”, “456”, and “789” as well,
OK is output each time the data is read.
When the read data does not match the registered data, NG is output at the time the unmatched data
is read.
In 3-point-B verification, three data items of Master data 1 to 3 can be registered with one record
number. Each time the data is read, the verification is performed with Master data 1 to 3 in that
order. Then, the OK/NG result is output.
The operation flow for working with the 3-point-B verification function is as follows.
