Functional Upgrades for Unit Version 4.0
1-4-1 Online Editing of Function Blocks
Unit Version 3.0 or Earlier Function block definitions could not be changed during operation.
Unit Version 4.0 or Later Function block definitions can be changed during operation. This allows func-
tion block definitions to be quickly corrected during debugging. It also allows
function blocks to be used more easily in systems that operate 24 hours a day.
1-4-2 Input-Output Variables in Function Blocks
Unit Version 3.0 or Earlier The data size of parameters that could be passed to and from function blocks
was limited to four words maximum. It was thus necessary to separate ele-
ments with large data sizes, such as data tables.
Unit Version 4.0 or Later Input-output variables can be used to passed large quantities of data, such as
table data.
