Dear Willybong, Thanks for your help, I unlocked protect function block FC161 and FC166 also but I didn't find out any position data transfer to DB24.DBD16, I want to modify a little data before transfer to DB24.DBD16, Could you test force valve with input analog PIW176 ( when you increase value over 127 decimal, it will return negative value, I don't know why), DB24.DBD16 to display actual value on Intouch Wonderware SCADA, Could you please check programs again with unlock function block, see my attachment file Thanks and best regards, huynhhai77 Attachmentunlock_protected_myplc.zip (84 Downloads) |
