We used the RET function block to control the operation of two dryers. Each dryer is expected to operate for a number of hours before switching to the second dryer. The operation is seamless with the present configuration. My challenge is when there is power failure or controller download, the RET blocks reset to zero thereby interrupting the sequence.
We've checked the "Restore parameter values after restart" check box yet the problem persist.
Kindly assist with suggestion on how to solve this problem.
Thank you

Update from Emerson Exchange 365 David Nelson For power failures, the "Restore parameter values after restart" checkbox on the module property page only covers certain parameters on blocks, such as a PID block (there is an extensive list of the covered parameters in Books On-line). For parameters added to a module - such as Input Parameters - there is an separate checkbox that needs to be selected on the Parameter Properties page. For downloads, select "Preserve user-defined and critical block values" on the module property page. View online You received this notification because you subscribed to the forum.
