Thanks Andrew, Peter and Dave. I suspected there might be issues with these cheap drives. I suppose it would be wise to consider these units to not have a Modbus feature, then decide from there. The loose parts reminds me of stories about Listeroids, where it seems common practice to completely disassemble the engine before turning it over, to get all of the sand out of it and to check and refit parts that don't match. http://www.utterpower.com/listeroi.htm -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
