Blog Post: Listening for Leaky Valve Seats
Control valves are the workhorses of process automation. They touch the process and execute the control strategy coming from the automation system. Any valve seat leakage can impact the level of control and lead to safety issues, unplanned downtime, quality issues, increased maintenance costs, and more. To avoid seat leakage, control valves typically have been [...]

Blog Post: A Unified Approach to PID Control Steps 12-16 Tips
A unified approach to tuning has been found that enables a common and simplified method for setting PID tuning parameters. Key features can be used to eliminate the need for retuning to deal with different dynamics and objectives. Here are steps 12-16 in a methodology that integrates a unified tuning approach and key features to minimize implementation and maintenance efforts.
12. Add output tracking for equipment protection and a full throttle (bang-bang control) strategy for the fastest possible time to reach setpoint on startup and for batch operations.

Hi Andy,
Yes, I mean 3095MV and 3051SMV. We have both types in our company.
Can I understand as below:
For 3095, the flow accuracy will be bad as far as the P and T away from its configured P and T range.
For 3051SMV, it will not impacte by this.

Forum Post: RE: Virtualization Delta V (production Environment)
I see DVVS supports the use of 9.3 ~ 12.3 DV versions, but can I live migrate an existing 9.3 system to VMs?
Is High Availability supported for other versions or only DV12 (as per the note reference to six month after V12.3 ships)? Failover is a technology of windows so it should be supported for all VM’s.
I can create the same configurations without DVVS, either manually or with System Center VMM, is DVVS really required?

Forum Post: PVX-I/O with Deltav SX controller inverting analog inputs
Does anyone know how to easily invert an analog input with PVX-I/O on a Deltav SX controller? In Provox there was an invert option on the IST. We have had to bring the input into a scaler function block to invert it and then to a pseudo AI custom composite block. Also, in Provox you could make the 0-100% eng. units on an AI any direction and positive or negative. We have vacuum readings that were scaled in Provox at 20 for 0% and 30 for 100%. The top end of 30 is more vacuum. These we had to change on the DV AI block to be -20 at 100% and -30 at 0%.
Anyone else encounter these issues and find another way to work around them? Thanks

Dear All,
im new to this forum, and i have problem with deltav.
Since i installed the Kepware OPC on the Engineering Work Station, i cant use the export function.
if i use export then there is pop um message say "No Such Interface Supported"
maybe there is .dll file missing but i dont know exactly.
as you can see in the Picture
hope there is an answer for my problem.
thanks

Forum Post: RE: DeltaV FHX Export issue "No Such Interface Supported"
There is a chance that a DeltaV dll registration was replaced with a dll registered from the Kepware install. Try the following:
1) Close all DeltaV applications.
2) Stop the DeltaV service and any other DeltaV related services that may be running.
3) Run the command “regall /register” from the command prompt (If your DeltaVAdmin user password has been changed you will need to know that password).
If that doesn’t work, the next step would be to try an extended clean of the database.
If that fails or doesn’t fix the problem, try doing a manual export of the database using the command line utility dbimpexpclient. The structure of the command would be:
Dbimpexpclient.exe –de [Path to where export should go]
If that fails, try making a backup of the database and restoring it to a new database.
If all of the above fails you will likely have to uninstall and re-install DeltaV on your ProPlus. That will mean having to re-run workstation config on all of your operator stations and application stations. You should only do this if you have a known good backup of your configuration. I would suggest getting in touch with your Local Business Partner or Emerson rep or the Global Service Center for support in this last step or for any of the other steps I’ve described if you have any doubts or questions. Your issues are really beyond what should be handled on an open forum if the regall and extended clean don’t fix the problem.
