By your flag I assume you are in Thailand, I recently completed a large water treatment plant in Banglen (approx 1 hour out of Bangkok) as part of that project we installed 2 generators which are required to synchronize with the elect. supply. This system used a Woodward controller which in turn communicated with a PLC. If you are not to far from Bangkok it may be possible for you ask for assistance from the Comapny that is now running the Water Treatment Plant. If you would require some more information please let me know. I may still have some address details somewhere that may help
