Amen. I had that grandiose plan too, despite advice to the contrary. After a day or three of trying to figure how the Toshiba guys understood the Modbus spec, I finally was humbled into the one-driver-per-manufacturer model. I had to write a utility to talk to a modbus device, as an aid in reverse engineering: http://git.mah.priv.at/gitweb/modio.git , maybe its useful for the task > I built my code based on the GS2 module and > Michael's code. I guess I'll add that to master since it seems a popular base for cloning and I get no complaints here's another modbus driver for an Altivar which Martin Kaplan sent me: http://git.mah.priv.at/gitweb/emc2-dev.git/shortlog/refs/heads/altivar-vfd-comp -m ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
