Post by abuckie on Getting raw value as full resolution for ADS1115 ^{CODESYS Forge talk (Post)}
I just found this and I am getting a value larger than 16 bit, around 81000 something. I am reading a 5 volt value and I am using level shifters for the i2c bus. This is how I have the channel configured: ADS1115.usiAddress := 16#48; ADS1115.ChannelConfigs[0].Active := TRUE; ADS1115.ChannelConfigs[0].PGA := FSR_6144mV; ADS1115.ChannelConfigs[0].InputMux := Single_0; RawAnalogValue := ADS1115.Channels[0].Value; It looks like every value is a multiple of 3. Any idea where to look to fix this? I think i found what I want to change in UpdateChannels Channels[FChannelNo].Value := INT_TO_REAL(WORD_TO_INT(LValue) * GetFullScaleRange(ChannelConfigs[FChannelNo].PGA)) / 2048.0; I try to edit it but I can't, sorry if this is a basic question, I am new to CODESYS.

Post by ac-spr on Runtime variable that indicates a user is online to the code ^{CODESYS Forge talk (Post)}
Looking to access a variable at runtime that indicates a user is online to the code. essentially want to use this value to feedback to the user on the HMI. we use turck and bosch rexroth devices if this information helps. I was hoping there was a variable at the application level, or a library that could be used but I was unable to find anything. I know there's a pop up when you try to login/ go online to the code when a user is already logged in, so the system does provide an indication that it knows already online, but has no access to a value from what I can see. Any help is appreciated

Post by tk096 on High Cycle Times for SoftMotion_PlanningTask when using AxisGroup ^{CODESYS Forge talk (Post)}
Hi, under this circumstances the performance of a Raspberry Pi 4 should be sufficient to run a Softmotion robotics application. A closer look at the project would be required. Maybe you could contact the codesys support? Usually it is recommended to run the planning task cyclically every 2ms with task priority of 0 on a dedicated core. In the task configuration you can have a look at the average and maximum execution time of the planning task. You could use the function block SMC_TuneCPKernel (https://content.helpme-codesys.com/en/libs/SM3_Robotics/Current/SM3_Robotics/POUs/AdministrativeConfiguration/Computation/SMC_TuneCPKernel.html) to define suitable values for the parameters 'fSyncBufferDuration' and 'fPlanningInterval'. However, as previously mentioned, the performance of a Raspberry Pi 4 with realtime patch should be sufficient. The 'fPlanningInterval' parameter specifies the maximum planning step width in seconds. The cycle time of the planning task should not permanently exceed this value. A higher value reduces the computational effort, but can lead to a violation or no full utilization of the set limit values for velocity, acceleration and jerk. From a starting value of 0.016 seconds, the value should be increased gradually until the performance is acceptable. The parameter 'fSyncBufferDuration' specifies the size (in seconds) of the buffer between the planning and fieldbus task. The cycle time of the planning task must not exceed this value at peak times (this will lead to the error SMC_CP_QUEUE_UNDERRUN). A higher value can compensate for peaks in the cycle time of the planning task. At the same time, however, this also increases the latency for executing interrupts and aborting movements.

Post by xgongx on What is the insights of IoDrvEtherCAT.DCInSyncWindow? ^{CODESYS Forge talk (Post)}
It is well known that you need to increase the value of IoDrvEtherCAT.DCInSyncWindow to solve the "Fieldbus lost synchronicity" issue. In the official document, IoDrvEtherCAT.DCInSyncWindow is explained as the toleration of a certain jitter. But the official document doesn't explain what kind of the jitter is. Is it the jitter of DC sync deviation, master timer or something else? It is very important to know the insights of IoDrvEtherCAT.DCInSyncWindow. For example, if it is the toleration of DC sync deviation, and the official recommending value is 200us for CODESYS SoftMotion. It means maximum of DC sync deviation is 200us. It is unacceptable for some high precision motion control tasks, for example high speed gear task, etc. Increasing the value of IoDrvEtherCAT.DCInSyncWindow will increase the deviation of motor rotation sync if it is the toleration of DC sync deviation. So, would anyone tell me what the insights of IoDrvEtherCAT.DCInSyncWindow is? Thanks.
