your plc-type is ?

have you set a gateway address in the PLC

Hi Peewit !

I am using a Bachmann PLC.I have set the gateway address in the PLC.

Hi !

I want to send email with the smtp_client_demo using a free public mail like gmail.
I have successfully compiled and run the demo code, but unfortunately I cannot receive the email
in my account.
I am getting the errors:

SMTP_ERROR_T = 1
SMTP_ERROR_C = 16711680

According to oscat documentation:
-  Problem: DNS_CLIENT --> Format error: The name server was unable to interpret the query.

I don't understand it clearly.
I have attached a screenshoot of my program running.

Thanks for any help or hints.

I am new to oscat.  :-[
I try to run the demo program for FTP.
I have exported the FTP demo and import it in my new progarm.
I have added the required library.
But I keep getting the following error:

Error 3554:  Task Configuration (3) : Task entry 'FTP_CLIENT_DEMO;' must be a program or a global function block instance.

Thanks

Bitte kann jemand mir helfen zu schreiben/lesen einer datei mit oscat.lib .
Ich habe schon oscat-lib dokumentation gelesen aber das ist nicht genug...
Ich brauche nur ein kleinen Code Beispiel.  :)


System:
- Codesys 3
- Structured text

PLease in the Oscat netlib documentation P.119-120. There is the following assignment format to the function code.

VMAP[m].FC := DWORD#2#binary_binary_binary_binary; (FC n, n,n, n)

where n = function code (I understand clearly).
m = index of the VMAP array.

e.g:
VMAP[1].FC := DWORD#2#00000000_10000000_00000000_00011100); (FC 2,3,4,23)
VMAP[2].FC := DWORD#2#00000000_10000000_00000000_00011000); (FC 3,4,23)
VMAP[3].FC := DWORD#2#00000000_11000001_10000000_01111010);(FC1,3-6,15-16,23)
VMAP[4].FC := DWORD#2#00000000_11000001_00000000_01011000); (FC 3,4,6,16,23)

Can someone tell me the meaning of this expression ?

Regards.

Look in the documentation in Chapter 9.13 and 9.14

Thanks Peewit. I get it now  :D
