Post by smartcoco on Bit / Bool data types in function parameters ^{CODESYS Forge talk (Post)}
Memory addressing is measured in bytes, with BOOL occupying one byte. BIT is quite unique as it occupies one bit. So, try not to use BIT in the program. You can use the Unpack function to solve your problem.

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 paro on OPCUA array max length? ^{CODESYS Forge talk (Post)}
I think the amount of data is already relatively high and maybe it has something to do with that? Maybe also the CPU load of your device? an array with string(5000)? and have you tested with how many array elements it still works?

Seems like you use SIZEOF as size, but you need to use LEN as size of data which you want to write.

Post by tjacks on Opc UA Data Source Client Browse Error in Codesys HMI ^{CODESYS Forge talk (Post)}
Codesys V3.5 SP21 Patch 3 Codesys HMI 3.5.21.30 I'm trying to connect to an OPC UA server on a Kuka robot controller using Codesys HMI's data source manager. I get through the login phase and the client browses most of the data structure on the server but errors out toward the end with a generic: Error while browsing the client, Failed with service result: BadUnexpectedError. If I complete the data source setup and try to update variables, I get the attached stack trace for the error. I've tried several different endpoint and security options. Most get me through the login but all error out while browsing. UA Expert happily connects and browses with the same configuration. I've connected this same version of Codesys to TwinCAT OPC UA servers and Siemens PLC OPC UA servers. Any ideas on what may be causing the generic BadUnexpectedError during OPC UA server browse?

Hello good morning everyone I would like to ask a question, is it possible to directly connect a device that only contains modbus RTU communication through an R-45 connector, directly to the PC? Or would you need an intermediate device to achieve communication? It would be of great help to me because I cannot achieve communication between the Codesys simulator plc and a Fuji Frenic mini VFD, please help me if anyone has had the same experience. Thank you so much
