How do I read the M200 or M221 Real Time Clock from the HMISTU?


29 November 2022

It is not possible to access the M221 or M200 %SW memory addresses directly. These must be mapped to %MW addresses in the PLC program. Then set the %MW memory address for the Seconds as the start address in the Dialog Table in Vijeo Designer.
