Saitel DR - Can one have more than one Modbus Master connected to HUe?

[Rajeev_211]

I have made one modbus TCP slave PHG66301A in saitel HUe, when I am checking the modbus slave data on modbus poll master, its working and reading the data properly without time out. But the moment i am connecting another laptop and modbus poll master for reading data, the connection in both are getting disconnected, means its only allowing only one modbus master.

can someone tell me why saitel HUe is allowing only 1 modbus master connection at a time not two or more??

I have two modbus master gateways which are reading and writing data of saitel HUe.

I have two saitel HUe which are having redundancy between them and a common virtual IP as well.

Both gateways are trying to read from the common virtual IP at the same time which is not working but when i disconnect one gateway its connecting properly.

Can someone check and advise me on the maximum modbus master connections from saitel HUe?

hello @Rajeev_211 

You can have more than one modbus slave linked to the same called connections as you can see in the link below.

.... but I remind you to add different slave addresses as a mandatory condition.

On the other hand you also have the chance to add another destination in your configuration or even more, with the same data points or different mappings and also can add additional channels with different ports to avoid traffic discrepancies. (503, 504, ...).

Take a look at the document attached in the link above with all the limitations.
