hi PCS7_idt Actually we have a ET200 configurator from the Siemens site (https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&lang=en&objid=20208582&caller=view). It is actually a very useful and well designed tool for this configuration. Porblems come when you have also other devices like PA instruments and VVVF drives and maybe other 3rd party equipment. The saving depends on how distributed the configuration is. In case you have a lot of smaller stations then one Y-Link would be used in place of many redundant packages in each station. (provided the route between the station is not so hazardous or too long to justify redundant bus and thecustomeragrees to it) the savings are quite a lot. Of course in that case we would go with ET200S for the complete system to avoid thetroubles with lesser trained maintenance. What I keep wondering is what would a redundant bundle ET200M with Active Bus modules offer more than what a Y-Link and ET200S station would offer, because clearly it is more expensive solution? Thanks for you inputs |
