Are you working with belt conveyors for instance? Tell us more about your application to let us select the most suitable modules for you.

While each bag moves on the conveyor, its weight must be checked (must be inside some maximum and minimum weightlimits). The belt conveyor must always be in motion and must not stop for weighing.

Hello, Now it is clear for me. You have to select a belt scale (MSI for instance) and you can use BW100 / BW500 and use its own DO for enrgize reject pusher if applicable. Or you can use Siwarex CS. Hope this helps.

However, I am not quite sure that BW100/500 are intended tobe used for discrete product weighing, as individual bag check weighing, but for bulk material weighing by intergrating weight.

About the choice of weighframe, I would contact a company who build complete weighframes for these applications. As far as I know, Siemens only builds weigh frames for a continuous flow of material on the belt, not to weigh separate bags. The siwarex FTA has different preprogrammed applications. I would base my choice on the PLC platform you are planning to use, and the ease of programming. If you can avoid writing a complete PLC program by using one of the preprogrammed applications in the siwarex module, this saves you a lot of time for programming, testing and troubleshooting!
