Post by peterkcontrols on Making a Visu Element normally invisible and visible if variable is true ^{CODESYS Forge talk (Post)}
Hello I would like an element in my visu to be only visible when a certain Variable is true, currently it is only capable of being normally visible and then invisible if a certain variable is true. Is this possible without programming a new variable to be the opposite of my desired control variable? Thanks.

Problem solved The client modbus cycle time was linked to a task at 500ms. Whereas the channel modbus was at 200ms. Certainly problem of packages synchronisation. I let the client modbus cycle time to be handled by itself (See attachement) --> "Use the bus cyle time parameters" (traduce from french) See attachement

I am using Codesys Control RTE V3 Version 3.5.21.0 I am not sure what you are asking. Which hardware ID has the network interface card? I have ran ipconfig /all and attached an image. Let me know what other information I can provide to you to help troubleshoot this problem. Thank

Post by madskaizer on Exception when OPCUA datasource disconnects from Server ^{CODESYS Forge talk (Post)}
We have similar issues, with crashing PLCs, but this ranges from 3.5.16.40 to 3.5.19.70. Which log made you confirm the exception crash? I am currently looking for evidence of what causes our PLCs to crash. Network stability could be an issue with latest security roll-outs like 802.1X and segregation.

Post by benemenn on Type mappings in Datasource ^{CODESYS Forge talk (Post)}
Hi! I am trying to achieve the same issue. Has there been a solution? I can create the mapping, and map the local variable, but somehow the object does not update. Furthermore, i have an issue where codesys doesn't let me set ReadWrite accesses to the variables in the "Type Mapping" place. The access will simply not be set. Has anyone ran int that issue?

Post by snguyen on Atomic and Shared memory? ^{CODESYS Forge talk (Post)}
Hi, I've read that you can perform Atomic instructions like AtomicReadLInt on variables. However, I'd like to know if this uses stdatomic internally. My main question is : Is it possible to share atomic types in shared memory with CodeSys. If so, what types should they be declared as? If not, are the atomic functions lock-free or does it use a mutex?

Testing Codesys CNC. SMC Interpolator Throws me an error if my code surpass approximately 32000 lines of code. (SMC_CNC_INTERNAL_ERROR) What is the max lines of code SMC Interpoltor can handle ? I've been thinking breaking the code up into smaller sections, but that gives me a lot problems later if i want to use "Blocksearch" etc. I need to run approximately 2000000 lines of code.

Hi, yes now its working, to get "QUEUE.bFull" to work, I've had to set the "QUEUE.nNumReservedEntries" to 3. (I tried different values here, only effect for larger values i can see is the the queue capacity gets smaller.) I've noticed the movement is slowing down when it reaches the end of the "fill Up", must be because of the "checkVelocity" can only see the current "QUEUE". Any way of solving this ?

Hi everybody, I want to execute more than once cam fb simultaneously so blending cam and thus blending velocity without stop motion. But as far I know codesys dont support directly cam blending. But I beleeive there is a some solving. I request your support. But there is important thing is I want to change cam table cam on the fly. For example FlyingSaw application change cutting lenght.

Post by wagokurt on CODESYS Visualization M License Fails to activate on Linux SL <sup>CODESYS Forge talk (Post)</sup>
The fix for this is when you install the control SL license, there is a checkbox for the Visu S license option. You must click this option. The Visu M is technically an upgrade to the Visu S, if this is license is not installed them the Visu M will fail as shown above. Thanks JoJo for the solution!

Enabling Anonymous Login 1. Navigate to 'Device' > 'Communication Settings' > 'Device'. 2. Next, click on 'Change Runtime Security Policy'. 3. In the new window, find and check the box for 'Allow anonymous login'. After completing these steps, you should be able to communicate with the OPC UA server.

Hello TCIS_Send needs to be longer than 4 bytes because idata is 28 bytes long. There may be other ways, but I would make a UNION with string/array of bytes. Write your STRING into the AsString part then copy the AsBytes part into TCIS_Send (Elements [3] to [30]) then 252 would be in [31] (I've assumed the idata is always the same length)

Try changing the port mode to digital input for each port you want to have 2 inputs in the connection settings for the device. I've successfully used ports for inputs on an AL1920 this way, I think the procedure should be the same for an AL1332.
