Goals and Symptoms
Soft starters and VSD Catalogue April 2003 (latest what I have in my hand) is not contains details about Interbus-S communication in Section 3, Communication.
There is only a short list on page 2/135 with the available solution.
Why we have 3 different Part number in Vantive? In the catalog we have only the VW3-A58304E. Is it possible to buy VW3-A58304E, which not requires external power supply? If yes, it's missing from the Printed catalog.
Would be nice to give detailed informations with each type of communication option board, like we provide for MBPLUS, FIPIO, ETHERNET in Section3. (I mean network topology, reccomendations, etc)
Missing the Interbus-S, CAN-Open, Profibus-DP details there. Can-open will be intersting in point of communication, because Advantys and the new OEM strategy in Schneider is based on CAN!
Pls see the possibility in the next version.
Causes and Fixes
VW3A58304 = First version, not recommended ( not exernal 24Vdc )
VW3A58304E = Second version with an external 24Vdc to supply the option card even the ATV is switched off because Interbus-S is a circular ring and if a device is switched off, you loose the bus.
VW3A58304EU = Version with USA documentation.
For MBPLUS, Fipio, Ethernet you can find a large documentation in IANET, it's not possible to put more details in the catalog because it's a catalog and the customer or enginnering department is supposed to know the concerned field-bus.
