I have a PLC with RS-232 output. My customer does not want to use a laptop to download data from the PLC. He wants to use ethernet connection and download remotely. Are there RS-232 to ethernet convertors available for this kind of application?
I have used these and the Digi, and they are all on a fairly even plane. I prefer the devices that are DIN rail mountable and +24 VDC because they can more easily integrate into the same cabinet as the PLC and use the same power supply
I have used the Lantronix units for several applications, PLC, Traffic Detection and Video Switch control. In all applications I have found them to be quite good, easy to set up and quite transparent. The applications have also been through remote dial up (I'm a dinasaur!) and worked seemlessly.
Do you have the model number of the unit? All I need is one port on RS-232 DB-9 Male converted to ethernet. I need to be able to assign IP address for the convertor.
This is the DIN rail mounted Lantronix terminal server. It has an RJ45 interface, but you can get a RJ45 to DB9 converter easily. This would be more in line with the industrial environment.
