Looking for a gateway from Ethernet to 16in/16out digital I/Os

6 posts in this topic

Hi!
I am using a Ethernet/IP and a Brainbox ED-588 as a gateway to a PLC that has 8 in and 8 out Digital IOs.

In order to interface with other types of PLCs I am looking for a gateway that has 16in and 16out digital I/Os

I have also been asked to work with NPN output, not PNP. This can be achieved using yet another component, but if possible I would like the gateway to be configurable with NPN/PNP output.

N.B. The orignial protocol doesn't even have to be Ethernet/IP, I might be able to work with other protocols as the source.

Products that I found do not have enough IOs

 

Thanks!

Stride field IO has a variety of options. See the link above.

What about just using a Click PLC.

The standard Ethernet port on the click will communicate Ethernet IP, Modbus TCP, etc.
You can then add the additional IO that you want. The digital cards can be NPN or PNP.
Software is free and you can just use the PLC for its IO reading and writing.

Garry

Thanks!

That was very helpful

It's a very interesting idea (using a PLC for its IO reading and writing).

Could a similar solution also work as a gateway to several protocols? I am looking for a way for one end device to be able to work on most popular PLCs. Is there such a simple PLC that can be configured to work with multiple protocols?

Red Lion's DSP (Data Station Plus) and the entire Crimson line of MHI can do Protocol conversions and I'm told now has a OPC-UA server in it.
Maple Systems HMIs can host tags to it's internal modbus TCP server or you can license it's OPC or MQTT service on them.
Allen Bradley's Micrologix 1400 Ser. B can read Modbus TCP and then your Controllogix can read from it.
VTscada can output a tag from one device into another without scripting.
Once, long ago I scripted one tag to output to another in FactoryTalk View SE based on rate of change.
Click PLCs can be read via Ether/IP assemblies from Allen-Bradley PLCs and presumably most other PLCs that support Ether/IP Assembly I/O.

The Red Lion in a great choice I'll agree. Also has Ignition Spark license already.

Do you need a complete PLC/PAC solution? If not, we use the Wago IO (It has a CLX AOI too) for Modbus add-on. Coupled with a XetaWave or Banner radio to get the very remote station into our ethernet'd plc.

Yes, you can find PLCs that will work with several universal protocols. 
As mentioned the Click PLC would be the least investment. It can be read from Ethernet IP, Modbus TCP (Ethernet), Modbus RTU (Serial) or any customized Serial communication. It can use Modbus TCP and Modbus RTU as masters to read information from other controllers.

The BRX PLC (Do-More) also has the above protocols that you can read, but it can also be used to collect data from Ethernet IP, Modbus TCP, Modbus RTU, and MQTT.

It depends on what you want to communicate and the protocols you want to support.
