Hi @allprimo, This is an old post, however, did you get anywhere with this? I was starting a program in C# to read NVLs, it was more so for troubleshooting. It is basic ATM. Mike.

Ticket #167: Network Variables communication protocol is needed
CODESYS Forge
support
(Ticket)
Hello, We are developing an embedded application to communicate with a PLC. The plan is to use CodeSys UDP communication. I mean, using "Network Variables". As far as I know, the communication protocol is called as "3S protocol". Does anybody have the details of the protocol ?

You never stay in a method. You need a block to do that. Something like: VAR button:BOOL:=FALSE; count:UINT:=0; END_VAR IF button THEN //read pressure count:=count+1; IF count>1 THEN button:=FALSE; count:=0; END_IF END_IF

Post by davidbo on How to stop dhcpcd and use SysSockSetIpAddressAndNetMask to set address?
CODESYS Forge
talk
(Post)
It is stated: "Dynamic ip address, provided by DHCP, BOOTP, etc. Cannot be changed by SysSockSetIpAddressAndNetMask()" Therefore I try to stop dhcpcd and flush the eth0 like this VAR CONSTANT flushIP:STRING:='sudo ip addr flush dev eth0'; stopDHCP:STRING:='sudo systemctl stop dhcpcd'; END_VAR SysProcessExecuteCommand2(pszCommand:=stopDHCP, pszStdOut:=stdout,udiStdOutLen:= SIZEOF(stdout),pResult := ADR(Result)); SysProcessExecuteCommand2(pszCommand:=flushIP, pszStdOut:=stdout,udiStdOutLen:= SIZEOF(stdout),pResult := ADR(Result)); Besides losing the connection when flush occurs the CODESYS halts, seen on the display and I cannot see why, because I have lost the connection from my IDE. Why does the flush command halt the execution of the application?
