Straton/ModbusTCP driver - How to set parameters?

[mhanusek]

Hello.
I'm trying to set a tcp port and ip address in a modbus tcp slave driver.
In the driver configuration are not fields.

MODBUS Slave opens the IP port of the Runtime. In zenon Logic it is by default 1200 (so not 502). I do not remember default for straton, maybe 1100?. If you wish some particular port then you have to start the T5 runtime with this port (as 'Standard port' setting).

I understand. I connecting to port 1101 and it is ok. But i need change number port and ip address.

Hello,

For the moment this is not possible to change the IP address opened by the Modbus Slave.
I guess, the goal is to force the Slave to open a specific Ethernet card.
Currently, as my colleague said, it opens the default communication port (1100 on a straton runtime) of every device's Ethernet cards.

In order to open another port, you can either start the runtime with a specific option (./t5runtime /evsport=xxx) or use the MBSLAVETCP block.

This block allows to open a different port than the communication one.
Eg.:
    Inst_MBSLAVETCP (bOpenPort , 1105 );
    bOpenOk := Inst_MBSLAVETCP.OK;

Normally this block is only for test purposes; thus it is not officially tested during quality assurance tests so use it carefully. This is also why it is not documented.

I hope it answers to your request

Thx for reply.
Its problem for me. I have 2 two physical interfaces and I need run modbus-tcp only on one interface, on custom tcp port.

Well... The only thing that I can say for the moment is that this request is only registered in our database with the ID#140
 >> Attach MODBUS Server to an IP adapter (for security) <<

I added a comment saying that another customer just asked for it. But, for the moment this is not possible to say when it will be implemented, sorry
