Hi,
I would like to integrate a measuring system using the MODBUS protocol to my NetXMS system.
It contain an RTU-TCP MODBUS converter module and four measuring devices connected via RS485 bus.
The converter module has an IP address, through which the four measuring devices can be accessed, but each on a separate port number.
Is it possible to request in NetXMS all four instruments via MODBUS from the same IP address but different port numbers?
Thank you in advance.
You can create four nodes enabling "Communication through external gateway" checkbox on them (actually, on three of them, so one of them will be treated as main node and NetXMS will read network topology for it).
For each node you can now set specific port.
If you want all DCIs on one node, you can use Source Node Override in DCI properties.
Hi Filipp,
Thank you for your support. The "Communication through external gateway" checkbox solution works perfect.
BR, Zsolt
