Post by camjam on BOOL variable in OPC UA and modbus simultaneously ^{CODESYS Forge talk (Post)}
I have come across this. The only way i could get it to work would be to define a word that is also the same address as the Bools. eg %MX600.0 through to %MX600.15 would be individually defined in the variables and them have another variable word defined at %MW300. You still need to break out the word in what ever program you are using to read/write the OPCUA tags.

Post by umair on Code for reading 4 address to get 1 value of sensor (Ethernet IP) ^{CODESYS Forge talk (Post)}
Hi all, I want to ask, how do I write code to read multiple address for Ethernet IP communication protocol? Because this multiple address will produce one reading of a sensor that I am currently using. I want to read the value of the sensor. https://global.discourse-cdn.com/business6/uploads/wago/original/1X/7a79f4ad7ce474b9383b8550356d984defd9f3a0.png The addresses are in Byte. The 4 addresses are 89,90,91,92. Thanks in advance. Best regards, Umair

Post by andrax on Variable Length Array - Cannot mix variable and fixed length dimensions? ^{CODESYS Forge talk (Post)}
Arrays with variable lengths are a bad idea. This makes your system unstable and can lead to crashes. Declare your array large enough to reserve enough memory

Post by dtamm on How to read string from CharBufferPtr? ^{CODESYS Forge talk (Post)}
Solved it! The simple answer was to declare a variable as POINTER TO STRING and assign the GetMessage result to that variable. Then, the ^ operator can be used to extract the message as string.

Post by naks on Change IP address from IEC code ^{CODESYS Forge talk (Post)}
Hi, I'm working with wago 750-8212 controller. I want to change the IP address of the Ethernet adapter from webvisu. I have read some other threads in this forum and I have tried the following: Added the following text to the config file CODESYSControl.cfg: [SysSocket] Adapter.0.Name="br1" Adapter.0.EnableSetIpAndMask=1 Used the below code : IF xUpdateEthernet THEN Ethernet.Enable := FALSE; Reconfig ( xExecute := TRUE, itfNode := Ethernet, eError => ErrorReconfig, xBusy => xBusy, xDone => xDone, xError => xErrorReconfigure); IF Reconfig.xDone THEN ErrorCode := Ethernet.UpdateConfiguredIPSettings(IpAddress := NewIp, gateway := newGateway, subnetmask := newSubnetmask); END_IF IF Reconfig.xDone OR Reconfig.xError THEN reconfig(xExecute := FALSE); END_IF Ethernet.Enable := TRUE; Reconfig(xExecute := TRUE, itfNode := Ethernet ); END_IF I could change the IP address but when i restart my Controller then the IP address resets to the original, Is there anything I have missed, what else can i try ? Thank you in advance.

no nowadays I would recommend connect by name. Which is the default I guess since some versions.
