The wind turbine is named "Sentic Convoy 537"? Or, does the PLC that controls
it bear that name?
If the former, what is the name/model of the actual Siemens PLC incorporated
into the device? Why can't you find documentation regarding that PLC's
"interface" (since you claim noone can "interact" with it)

Yeah; look at the interface description for the device and see if
there's a "rotor rpm setpoint" parameter listed. If not, are you sure
bad things won't happen if you alter this parameter?

Contact the vendor.
Contact Siemens (for PLC documentation).
Dump the EPROM and reverse engineer its contents.

Dear all, I have a wind-turbine that is equipped with a Siemens 80c537 CPU
based PLC, named Sentic convoy 537. Seems that today nobody is able to
interact with this PLC.
I have recognized the eprom (AMD 27c512). I need to modify a functional
parameter (the rotor rpm set): can anyone suggest how to do that?
I have an eprom programmer and I can read the eprom content. But I need
further help to do my job....
Please, can anyone help me?
Thank you!!
