Dear All After going through a lot of documentation and threads in the forum, I have an inquiry about the possibility to change a Core (in a TMR Configuration ) while the unit is online. As far as I am concerned the Mark V does not have the luxury of making Online hardware changes. but when it...

As per the PCB drawing the of SDCC the U9 chip is referred to as the only EEPROM compared to U11 U12 U22 U23. 1- As far as I am concerned, when we perform download to the core, all that data will be stored to U9 only is that correct? 2- During any replacement of SDCC board with new one...

In Windows 10 VM I am creating a Virtual Controller for a MarkVIe package. Microsoft [KM-TEST] Loopback Adapter created and correct IP addresses were added. I got normal response when I ping the controller IP address through command prompt. However, When I create the Virtual Controller and put...

Dear all Can anyone help have more insights in regards to the Function of VPL Tracking and VPL Control of Limiters Function in GE Steam Turbine? Regards

Dear all At the moment I am working at a power plant of six frame 6Bs, the fuel gas system is composed of a DLN1 SRV + GCV1 and GCV2 woodward valves. Customer is struggling to check to part number of the LVDTs imbeded inside the gas valves to make procurement and all GTs are in operation hence...

Good day everyone In order to repair one PAIC IOpack having a problem with BPPx board. the board reference is IS200BPPCH1ACA. I am looking for the circuit board drawing if anyone can help me with the situation. Thanks in advance

Dear All I am looking for a MARK VIeS turbine control application (Master file only) which includes in its hardware configuration the YSIL cores safety protection module IOPACK. Thanks in advance

Hi everyone, After working on both heavy duty and aeroderivative gas turbines and being aware of the major differences of the control theory of both, I have some questions about the mechanical side of the aeroderivative GT. I know that (correct me if i am wrong) the Aero GT shaft is much...

In our compression station we have frame 5 machines. After visual inspection of the gas valves actuator assembly (bolted to stationary base plate) of one machine, I noticed a SMALL oil leakage (see the picture in the link below) from the GCV actuator plug while the machine was running. (notice...

It is about the "standard droop speed control" and how it can be affected by the FPRG or a bad calibration of the gas valves...etc. Compared to the CONSTANT SETTABLE DROOP SPEED/LOAD CONTROL, The STANDARD DROOP/SPEED CONTROL has "no FSR value feedback" in its regulation loop. This mode of...

Peace everyone So i managed this 6 months to learn how create a virtual controller and create a simulator for some MK VI and MK VIe projects (which are provided by the simulations blocks) And recently i am trying to do this with a MK VIe and MK VIeS projects, i configured the both virtual...

Now with MarkVIe we can have a PPRO pack which is safety certified (IEC 61508), and it can be used in the IEC 61511 certified safety loops. please can you tell me exactly what GE added to the hardware or the software (board processors) which make it able to be safety certified?, In other...

The Mark VIeS is the safety platform of the mark VIe, and it has been certified to be SIL3 (controllers and IO packs). It can be a TMR, DUAL, or SIMPLEX configuration. But what i want to understand deeply is: does this safety platform has to co-exist with a control platform (mark VIe) in the...

I just want to share and confirm an information that i have about using two gas valves (SRV and GCV) in the frame 5 GTs. The first valve SRV (speed regulating valve) regulates the infravalve pressure (between srv and gcv). This pressure depends on the hp speed. WHY? because the amount of fuel...

Can any one please give more explanation about the dual configuration in mark VIe regarding the voting and the processing of critical signals. For example the trip solenoid relays in the TRPG card will have a configuration of 1/2 or 2/2? Or we do not have any voting at all and we do have a...

i would be so grateful if you could explain exactly how the OPC DA server performs when enabling it in the workstationST: - In the OPC DA server tab, does the "Client Driven variable" means the variable of the workstation which are held by the OPC? - does it copy directly the EGD data...

I managed to configure a Mark V controller into ToolboxST application using the Mark V feature in the WorkstationST component editor. Everything went okay, and i finished the operation by adding the Mark V maintenance tools( logic forcing, dynamic rungs display...etc) using the "REBUILD START...

After studying the CSRGVPS algorithm of a 5002B heavy duty gas turbine, I found that the inlet guide vanes are automatically positioned closed during a start-up and a shutdown sequence to avoid gas turbine compressor pulsation or combustion pulsation. I found also to protect the axial compressor...

After making an upload from the controller in MARK V (HMI), i'm looking for decompiling these 'ap1' files to have source '.src' files again. would you please help me with that.
