Oja,
I've the same problem with a genset controller, and i've found a walk around:

- Create a new data source for your modbus slave with just one point (the write only register) and without slave monitor points.
- Disable point read exception alarms
- Use an update period of 9999999 hours (it'll bother just at first update, never alarm again 'cause next update will be at 10 years ;))

You need to create a new data source because you need to receive point read exception alarms from all the other read and read/write points on your modbus slave.

¡Excelente! Encuentro espectacular que se genere una traducción al español.

Para cooperar, ¿podrías considerarme, por ejemplo, con la tarea 3 (lineas 501-800)?

¡Exito!

You're right. USB-Serial adaptors aren't the most compatible peripheral in the world.

But my problem is different, 'cause i use a Serial to Ethernet adaptor (Moxa calls it "device server"). If i install a driver on my PC, i got a virtual COM port though ethernet.

When i use modpoll for test (www.focus-sw.com/fieldtalk/modpoll.html) everything works:

But i can't select "Encapsulated RTU over TCP" on Mango (AFAIK, this protocol is supported).

I try to configure an Modbus IP data source without luck.
Transport Type: TCP
IP: **MyIpAddress**
PORT: 4001

jkyner says:

also works fine with the Moxa 5130 (a basic Ethernet/RS485 SDA that is not Modbus-aware) for those Modbus slaves that can handle the 6-byte Modbus TCP-RTU header forwarded over RS485.

Therefore... My Modbus slave is incompatible with mango?

Thanks a lot!!

Mango already supports Modbus RTU over TCP and UDP.

I try to configure a gen-set controller without success.

Testing with modpoll using "Encapsulated Modbus RTU over TCP" works fine, but i can't do it with Mango.

AFAIK, RTU over TCP uses a header different than Modbus/TCP. I need a new data source type? I try with Modbus IP without sucess.

I've a gen-set controller with modbus/RTU connected to a Moxa adapter.
modpoll (http://www.focus-sw.com/fieldtalk/modpoll.html) works great for test using "Encapsulated Modbus RTU over TCP", but i can't get it running on Mango.

It's possible to get this device works with Mango?
