Hello Yingsak,
On control logic, CMC and XE are identical. But the way the job are created are different. XE are designed so that Application Engineers can also create XE jobs unlike CMC which depends solely on Engineering which takes a long time in the past. Therefore CMC can be easily customized but not for XE. That’s the reason Mass Flow Logic has not been successfully ported to XE. Also, special logic will needs Engineering to review and decide if it can be implemented. Further, PnP are designed for single board machine, these machines at site are dual board configuration and therefore requires additional modification locally.
