Quick verdict
If you want a gateway whose model name spells out the PROFIBUS-to-Ethernet job, the Softing FG-100-PB is the easier recommendation. The protocol pair is right in the name, which makes planning the connection straightforward. The Bürkert 00307390 / ME43 is the pick when you specifically want the ME43 series from Bürkert because you already have a reason to standardize on that family. Both are legitimate fieldbus gateways; the deciding factor is whether you prefer the explicit Softing model or the ME43 family.
Side-by-side comparison
Here is the side-by-side look at what each option includes.
| Feature | Bürkert 00307390 / ME43 | Softing FG-100-PB |
|---|---|---|
| Listed Price | USD 249.99 | USD 233.89 |
| Price bar | ||
| Condition | Used | New - Open box |
| Gateway type | Industrial Ethernet fieldbus gateway | PROFIBUS/Ethernet fieldbus gateway, 1 Channel |
| Model | 00307390 / ME43 | FG-100-PB |
Where each product wins
The Bürkert wins when you want the ME43 naming and a Bürkert-branded fieldbus gateway. If you are working in a plant where ME43 series references already appear in panel drawings or spare-parts lists, that continuity can make the choice easier. The Softing wins when you want a gateway that is explicitly named for PROFIBUS/Ethernet and you want the protocol pairing confirmed directly in the product title. That kind of clarity helps when you are ordering from a list and want to avoid protocol mismatch.
Product notes
Bürkert 00307390 / ME43

The Bürkert 00307390 / ME43 carries a model number that matches exactly, so if you are tracking ME43-series spares or reference documentation, this is the unit that aligns with that family. It is a working pull that will come as pictured. That gives you a concrete idea of what to expect. The limitation is that it is used; you are getting a pre-owned gateway rather than a fresh box. The used condition is the trade-off you accept in exchange for that specific ME43 form factor. If you specifically want the Bürkert ME43 series for your industrial Ethernet fieldbus connection, this is the unit to consider.
Softing FG-100-PB

The Softing FG-100-PB is the more self-explanatory of the two. Its model name names both sides of the bridge: PROFIBUS and Ethernet. The '1 Channel' designation tells you it is built for a single PROFIBUS connection, so you can plan your wiring accordingly. That kind of specificity matters when you are comparing fieldbus gateways. The product title puts the protocol pair front and center, which is helpful for procurement and maintenance teams. The limitation is the single channel: if your machine has multiple PROFIBUS branches to connect, this gateway will not handle them all at once. For a focused, one-connection fieldbus bridge, the FG-100-PB is a strong choice.
Final choice by use case
Go with the Softing FG-100-PB when you need a straightforward PROFIBUS/Ethernet bridge. Choose the Bürkert 00307390 / ME43 when you specifically want the ME43 series.
