Engineering Workstation communication issue with OPC and Operator Workstation DROPs

We have following DROPs for our UNIT-2 on OVATION DCS 3.5.X

  • DROP 200 - EWS
  • DROP 160 - Historian
  • DROP 180 - OPC
  • DROP 210 - Operator workstation
  • DROP 211 - Operator workstation
  • DROP 212 - Operator workstation

Any graphics or logic changes that are implemented on the DROP 200 - EWS are unable to replicate on DROP 180, 210, 211 & 212. Recently we changed a graphics (spelling mistake) on our DROP 200 - EWS and when we tried to download it on the rest of the DROPS, only changes were made successful on DROP - 160 however on the rest of the DROPs it failed with an alert message popping up as "UNABLE TO COMPLETE THE REQUESTED OPERATION. CODE: 0x80004005. SOURCE: OVATION DEVELOPER STUDIO"

 

  1. Kindly advise on the reason that why changes are not been able to download on the DROP 180, 210, 211 and 212?
  2. Please advise on the way forward to rectify this problem?
