ION9000 used as a gateway

[mickkennedy]

Hi,

I'm trying to use an ION9000 as a gateway to 5 x sepam protection relay on serial line.

Communication is possible but performance is really poor.

ION is setup correctly to align with Slave devices re:baud/parity etc.

meter is setup correctly to act as a gateway in the advance section of IONsetup->modbus master module options etc.

my question is - is the comms performance of the ION 9000, acting as a gateway, known to be limited or poor? Is it poor in this case because of the fact that it is trying to allow 5 x SEPAM to communicate through it, would it perform better if the slave devices were a more basic  equipment?

Hello @mickkennedy , 

Better ask on the Power Meter forum:

https://community.se.com/t5/Metering-Power-Quality/bd-p/power-metering

Are your Sepam connected through ACE interface to the ION9000 ? ACE949 or 959 ?

How do you measure your system performances ?

What kind of Master is connected upstream you ION9000 ?

Hi Romain,

thanks for help.

I've also posted as you suggested on power meter forum.

5 x SEPAM have ACE949-2 interface each.

I'm reviewing the 'Time util%' and ''Avg request ratios' in Diagnostic viewer to measure Comms performance.

not sure exactly what you mean by your next question - "What kind of Master is connected upstream you ION9000" . the ION9000 is connected as an ethernet device and configured as a gateway to the SEPAMs
