Hi
I wish to recive a simple TCP/IP message, (see picture)
I have a python program sending every second a message
on the RTE I get this ?
CBSDSocketInterface: bind() failed: Permission denied
No Idea where to go from here ?,
Is it something I am not setting on the SUBSCRIBE_1 Fb ?
Thank you
Regards
Asterios

Hi Alois
I apprechiate the support, have gotten alot further, thank you
It is my first time playing with 4diac and IEC61499, I can see the benifits, I have 25 year experence in PLCs so hopfully once I get started I should not need to much of your time.
1/ How do I know its working ? Having probem decoding RD_1, from previous message how do I attached a word array ?
Like IEC1131 can I have global word arrays and attached it to the RD_1 pin ?
Screen shot 1, RTE and IDE running on my laptop, RTE working properly ? what is that error message ?
2/ On my Desktop PC, could not connect th server FB RD pin to the INT2INT ? both running ubuntu 20 10.
screen shot 2 also shows python program sending out a TCP/IP message and a example of a Fuji PLC recving a TCP/IP message in a word array,
Also the IDE that can't connect Pins.
Again, apprechiate the suport
Regards
Asterios

Hi Asterios,
great to hear that it works.
The language IEC 61499, which 4diac implements, does not have any global variables. So also 4diac does not have such.
I would handle RETENTIVE memory with dedicated SIFB function blocks.
Alois
