Post by mondinmr on Direct Pointers in IOMapping for EtherCAT with IoDrvEthercatLib.ETCSlave_Dia
CODESYS Forge
talk
(Post)
Using SDO, I can read the EtherCAT mappings and offsets from various registers like 0x1c12, 0x1c13, etc. When I obtain registers mapped in the PDOs and various offsets, I could technically access directly to the statusword, controlword, etc., if they are mapped. I have noticed that on IoDrvEthercatLib.ETCSlave_Diag I can find pointers to the input and output buffers. However, although the input buffer can be easily read by referring to what has been obtained from the SDOs, it is not possible to write to the output buffer, as it is overwritten in each cycle by the data from the IOMapping task. Is there a way, knowing an instance of IoDrvEthercatLib.ETCSlave_Diag, to obtain the pointer to the first data in the IOMapping? The offsets are identical to those of the PDOs, but obviously the data is a copy. For me, the cleanest thing would be to access the pointers on IOMapping, for DS402a devices to retrieve the key data and point them to internal references. I need to know this as, having developed our own motion library, I would like to simplify the initial setup by eliminating unnecessary and nonsensical mappings that can lead users to unnecessary errors. In the current version that we have been using for years, we have to map everything manually. I would like to pass only the slave reference to the FB_init constructors and eliminate the mapping.

Post by nmcc on Toggling Visualizations using HMI Physical Buttons
CODESYS Forge

(Post)
Hello, I am extremely new to using codesys. I have an IFM CR1102 HMI with physical buttons on the right side. I need to have these buttons toggle which visualization is active. I currently have ladder logic for when the button is pressed just need the action side for setting the active visualization. Any help is appreciated.

I'm no longer working with this PLC brand, but if I were you, I would try to stop all related Codesys services before the copy and restart them after that.

Hi, Yes it seems the program will not fit in your PLC memory. To resole this you can use the parameters in the CoUnit library to limit the various array sizes.

Hello, I encountered similar problems, and it appears they were linked to certain add-ons. Resolving this issue turned out to be quite complex. However, we managed to find a solution by downgrading both the "CODESYS Communication" and "CODESYS Recipes" components via the CODESYS Installer, accessible under the "Tools" section.

Ergänzung: Ich habe jetzt fopen.xExclusive:=TRUE; rausgenommen. Jetzt funktioniert es. Zusatzfrage: können 2 Schreibvorgänge in unterschiedliche Dateien parallel ausgeführt werden oder ist es besser sie gegeneinander zu verriegeln?
