Fieldbus gateways are the bridge between a fieldbus protocol like PROFIBUS and an Ethernet network, but the right choice depends on the condition you want and the interface details you need. The four options here cover a new Ethernet/IP module, an open-box PROFIBUS/Ethernet gateway, a used working pull, and an open-box Moxa gateway with serial interfaces. The price spread is wide, so the decision payoff is matching your actual connection requirements to the listed price and condition.
Quick Take
If you want a new module at a lower listed price, start with the Invertek OPT-2-ETHEG-IN. For a single-channel PROFIBUS-to-Ethernet bridge in open-box condition, the Softing FG-100-PB is the middle option. The Burkert 00307390 / ME43 is the used working pull in this group. And the Moxa MGATE 4101-MB-PBS is the highest priced option, with the most serial interface detail.

Product Notes
Invertek OPT-2-ETHEG-IN Ethernet IP Fieldbus Gateway Module
At USD 152.98, this Invertek module is the lowest priced option in the group. It is listed as new and carries the type PLC Ethernet Module, with a Country of Origin of the United Kingdom. The reason to choose it is a new Ethernet/IP-oriented gateway at a modest outlay. The limitation is that the item includes only what appears in the photos, so plan for any accessories or mounting parts you may need separately. The installation notes also emphasize that qualified individuals should handle the setup, so factor that into your decision.
Softing FG-100-PB Fieldbus Gateway PROFIBUS/Ethernet, 1 Channel
Priced at USD 233.89, the Softing FG-100-PB is described as New - Open box. It is a PROFIBUS/Ethernet fieldbus gateway with one channel, which suits a focused protocol conversion. Choose this if you want a mid-range price point and a Softing gateway for PROFIBUS-to-Ethernet bridging. A single-channel design keeps the wiring scope narrow, which is useful when you only need one PROFIBUS line translated to Ethernet. The open-box condition is the main limitation; the unit has been opened, so the product images matter more than they would for a sealed unit.
Burkert 00307390 / ME43 Industrial Ethernet Fieldbus Gateway Used
At USD 249.99, this Burkert gateway is the most you would pay for a used option in this lineup. The unit is described as a working pull, meaning it has been removed from prior service and is offered as used. It is an industrial Ethernet fieldbus gateway with model 00307390 / ME43. Pick this if you are comfortable with used hardware and want a mid-range gateway. The trade-off is the used condition, and the unit comes as pictured, so inspect the images carefully to set expectations for cosmetic state.
Moxa MGATE 4101-MB-PBS Fieldbus Gateway, 1-Port, Opened
The Moxa MGATE 4101-MB-PBS carries the highest listed price here at USD 969.00. It also provides the most explicit serial interface detail: 1-Port, 12-48VDC power, and RS-232/422/485 connections. Choose it when your fieldbus gateway needs those serial connections and the port count fits. Its condition is open box, and the price jump from the other three is significant, so reserve it for a project that genuinely needs the stated interface spread. This is the option to budget for when serial device variety is part of the industrial networking fieldbus layout.
Final Recommendation by Use Case
Start with the Invertek OPT-2-ETHEG-IN if you want a new Ethernet/IP gateway module at the lowest listed price. Pick the Softing FG-100-PB for a single-channel PROFIBUS-to-Ethernet bridge in open-box condition. Choose the Burkert 00307390 / ME43 if a used working pull at a mid-range price fits your maintenance stock. And if your project truly needs the serial interface spread listed on the Moxa MGATE 4101-MB-PBS, that is the one to budget for.
