System Details: We use hot redundant Modicon Quantum PLC with dual redundant communication having Remote IO racks (using CRP + CRA cards and coaxial cable). One rack is for Hot Redundant CPUs and other 12 racks are for Remote IO Drops (total 13 Drops). The model numbers of installed cards are...

Two frame V gas turbines, one having Mark V while other having Mark VIe control system, are installed at our site. Both turbines were installed with Mark Mark V, but one of the Mark V was upgraded to Mark Vie in 2019. Mark V was initially configured with I but in 2008 I was upgraded to HMI...

The turbine was synched first time after the upgradtion of MarkV to MarkVIe control system. The turbine was running on Droop mode. It was decided to check the ISO mode and turbine was put on ISO mode. Number of things happened when the ISO command was given. 1. Turbine did not go into the ISO...

I want to discuss the how synchronization in done MarkV and MarkVIe. I am not expert in this as I am going to read this first time in DETAIL. Please be patient if I am wrong anywhere. MarkV In MarkV three relays are used for Auto/Manual synchronization. These relays reside on TCTG card...

We are in the process of installing MarkVIe to our one turbine. The Exciter control system is also being upgraded to EX2100e. We have installed the new panels and are able to run the turbine till FSNL. As soon as the synch is initiated the lockout relay actuates and turbine trips (L86TGT causes...

Mark V TMR system is installed on our site for Frame V gas turbines. Mark V was initially configured with <I> but in 2008 <I> was upgraded to HMI (computer based and with cimplicity). Two gas turbines are installed at our site and each gas turbine has its own HMI in the GT compartment and we...

We have two GE Frame V gas turbines installed on our site. Each of the gas turbine is communicating with EX2000 and MarkV HMI (computer based and with cimplicity). The arcnet cables are terminated on CTBA card of the C core. Can we swap these cables on CTBA card? Is it possible while maintaining...

First of all I am thankful to the contributors like CSA and others for sharing their experiences. I am a silent reader of this forum and found it very helpful. I want to express my gratitude for all the contributors and moderators for such a wonderful forum. Mark V TMR system is installed on...
