Hello everybody,

I need some help regarding protocol routing in sicam TM 1703 emic RTU.
Let's say I have a device to X2(RS232) or X3(RS485) port connected through IEC 101 slave protocol, RTU connected to SCADA through X1(ETH) port (IEC104 protocol).
How IEC101 data can be routed to IEC104?
Configuration is performed via web browser.

Hi _spak,

I have experience with TM 1703 emic.

But in your choice of protocols I see something's that are not logical.

IEC 101 and IEC 104 are protocols that are used to communicate
with Control Centers.

In all SICAM TM RTU's there is no need to do any routing to IEC 101
and IEC 104. RTU spontaneously sends to IEC 101 and IEC 104.

As you might have noticed all signals you define in TM 1703 emic
you need to give CASDU1, CASDU2, IOA1, IOA2 and IOA3.

This is already IEC 101 or IEC 104 format.

For me it would be more logical if you connect IEDs to RTU
via IEC 103 or MODBUS and forward information to SCADA via IEC 101 or IEC 104.

Maybe you could describe in more details what is it you want to do.

Best Regards
Ensar

Hi Ensar

This is actually very common. Several devices use IEC101/104, although it is means for control centers.

Or maybe he has a TM emic to connect to other RTUs, concentrate information in one single RTU and send over one single channel to the control center. This is called gateway.

Hi Mike,

I understand that there is a need sometimes for this.
Gateway is common. In gateway the RTU that
concentrate should be IEC 101 Master and not slave.
I would do it like that in case of a gateway.
He didn't say which kind of device.

IEC 104 part should be Slave when connecting to SCADA.

_Spak maybe you could write what is exactly what you want to do.

Anyway there is no need to do any additional routing to forward to IEC 101 or IEC 104.

He could also use TOOLBOX to configure.

btw. I can't remember that there is SIPROTEC with IEC 101.

No, Siprotec has IEC103.

Webbrowser is free, maybe this is the reason for choosing it.

SICAM BC has IEC 101 but I haven't used them.
I dont know any other IED from other manufactures that has it.

Being free could be a reason to use it.

I hope _spak will replay and give more information.

Thank You for replies,

Let's say I have TM 1703 emic (ASDU 1 for example) witch is connected to scada through IEC104 protocol (Eth) port.
Scada reads information from points - ASDU 1 IOA 1, IOA 2 and so on.
I have connected IEC101/IEC62056-31 protocol converter (ASDU 2) to port X1 or X2 (protocol IEC 101)
It contains points IOA 1,2,3 and so on.
Actually, protocol converter communicates to electrical energy meters through IEC62056-31 protocol.

So my question is -it is possible to forward information from protocol converter to IEC 104 port.

I think this task is doable, through IL application, but I don’t know how to access (read, write) information object in IL .

I’d like to note that I’m trying to accomplish this task in web browser, ‘cause I don’t own toolbox (hopefully yet :)).

_spak to make it easy
which protocols you want in RTU?

I know that you want IEC 101 and IEC 104 but which one is Slave and which is Master.

This is not important to your question since Emic
automatically forward everything he receives to IEC 101 or IEC 104. That is the way it
works. You dont need to do any routing.

You just need to configure correct protocols and define signals.

IEC 104 slave
IEC 101 master

I don't have any experience with toolbox so I can’t argue with that. It may be true when configuring RTU via toolbox.

I’ve got a web browser example project which involves IEC101 and IEC104. Protocol routing is done through IL logic there. It simply loads IEC 101 signal and stores it in IEC104 address.
