Hello

The device is a gateway for the modbus connected devices. Reading the official modbus faq about such setups it states:

"Since Modbus TCP/IP is simply Modbus protocol with a TCP wrapper, it is very simple for existing Modbus devices to communicate over Modbus TCP/IP. A gateway device is required to convert from the current physical layer (RS232, RS485 or others) to Ethernet and to convert Modbus protocol to Modbus TCP/IP. Such a gateway device could be implemented using a PC. Commercial products to do this are available from several different manufactures. The Modbus device database can help you identify gateways and other Modbus devices."


So yes, I'd say you're correct that you'd need to speak Modbus TCP/IP to actually understand the slave device connected to the gateway.


Here's a snmpwalk of the gateway: http://pastebin.com/TbiZT8zn


And observium does not speak Modbus TCP, right?


Cheers and thanks

I can successfully monitor this in APC StruxureWare Data Center expert but trying to get away from that solution. Observium does find and see the tsxetg100 as a generic device but I don't see the PowerLogic attached to it.
