I was not looking for an ETH-1000 for the gateway to TCP MODBUS, but more for a gateway dedicated to this, less expensive. I am having difficulty to obtain IP access points on the network; the solution with a gateway allows me to have a single IP. but the solution with 2 ETH1000 remains...

Hello I was able to sniff the networks and go into detail. Finally there are not 8 RS485 in the same location but 2 RS485 in 2 separate boxes ! here is the diagram of what I need to recover. >I could use 1 MIRIUS in each box and a rtu to TCP gateway >maybe I can also use two ETH-1000...

8 RS485 of nearly 1000m are "joined" in this box, with 8 masters. They are not interconnected but it is the only place where I have access to the 8. the terminal resistor is probably "on the device on the end of the bus has integrated termination enabled by a DIP switch or similar " but I do...

the reason is essentially do not drill the box Ethernet is already in the box saving of a new box in a very dirty room The 8 RS485 are joined in this box with a very short cable length (not possible to put the MIRIUS in series) and I do not see where the resistance at the end of the line is...

outch ! big machine ... I also doubt that it could be cheaper, (with the 25 years of training necessary to program it :-) ) I have to find a solution for the dimensions (where to place the mirius, how to wire all this in an already monstrous and very old box). Considering the age of the box I...

the "server" is a computer station. I only have an IP connexion on it. A lot of IP solution but only IP solution. ETH-100 is good but I'm already hot in budget with 8 mirius and also in difficulty with size and cabling. initially I had in mind a single box with 8 RS485 and 1ethernet port...

If I understand correctly, as indicated on my diagram, I need 8 MIRIUS with a specific driver allowing the MIRIUS to sniff the registers that interest me and a recorder or a gateway allowing me to read the 8 MIRIUS transformed into modbus RTU slaves (1 per sniffed RS485). True ?

Hello and Thanks I's for a permanent solution (supply data to a supervision system for several years). The current RS485 system is very old but works perfectly. I'm looking to capture the data to better exploit them in a modern analysis system used for other things. I'm looking for mirius...

thanks

Thank you very much for your answer It's a very strange possibility FP B is pertinently described "Big endian Format" (the true one) and FP BB "xxxx with byte swapped" (so, the not true big endian). Why was it alowed to make "half" bigendian "half" litle endian. And 20 years that I use modbus...
