Hello, I'd like to write some parameters to axes from inside a function block where I passed axis by reference, using ETC_CO_SdoWrite. Is it possible to get the device address from inside the function block? Please see example below. Thank you!

Hello Can anyone see any problems with constant assignment as in the following statement: Coils[0] := Coils[0] OR (Buttons[0] AND Sensors[0] > 6); Rather than using the more verbose and vertically-larger: IF NOT Coils[0] AND Buttons[0] AND (Sensors[0] > 6) THEN Coils[0] := TRUE; END_IF Also, is the test expression short-circuited in the latter case? In other words, will the runtime move on after it sees Coils[0] = FALSE AND? Thanks

Its important that you know the difference between the two. Example 1: Coils[0] := Coils[0] OR (Buttons[0] AND Sensors[0] > 6); In this case the statements will be evaluated every scan and result in either true or false for Coils[0]. Example 2: IF NOT Coils[0] AND Buttons[0] AND (Sensors[0] > 6) THEN Coils[0] := TRUE; END_IF In this example Coils[0] will latch the result in a true evaluation, if you want it to behave the same way as example 1 then you need to do it like example 3 below: IF NOT Coils[0] AND Buttons[0] AND (Sensors[0] > 6) THEN Coils[0] := TRUE; ELSE Coils[0] := FALSE; END_IF However back to the real question. There is no problem using either example 1 or example 3, if im not requiring a latch i usually go with example 1 as it is more compact.

Hi starmaxou, Iβm facing the same issue you mentioned with the dependencies for the CODESYS Control for Linux SL installation. I was able to find the manual downloads for the CODESYS Edge Gateway and CodeMeter, but Iβm still stuck on the other two dependencies: CODESYS Control SL Extension v4.0.0.0 CODESYS Control SL Deploy Tool v4.10.0.0 Since youβve encountered the same problem, Iβd really appreciate any help or insights you can share on how you were able to resolve it. Any tips or suggestions would be greatly appreciated! Thanks in advance!

Hello, I face issues opening old Codesys 3 program when I am having a newer version installed. Unfortunately since I was forced to format my laptop after an unexpected crash. I lost all the setup files of the older versions. Is there ant where I can download it from? BR, Suyash

Hello SDO will write to the drive, not the axis, so you need to pass in the ethercat slave: VAR_IN_OUT Axis: IoDrvEthercatLib.ETCSlave; END_VAR Then you can get the address with: Axis.PhysSlaveAddr (as UINT)

Hello, Thank you for your answer. I'm afraid I was not clear on what I was trying to achieve. I'm trying to change parameters and command axes from inside a function block and the first thing that came to my mind was pass both the EtherCAT slave and axis to the function block (as image attached). But, I believe it's worse than just pass directly the EtherCAT slave address to the function block (is it???). However I was wondering if there was a way to get the EtherCAT address directly from the axis, so I don't need to pass the EtherCAT slave nor the EtherCAT address to the function block. Thank you again!

Hello, You can create a program in ST for AS228T using either DELTA ISPSoft or DELTA DIADesigner. The only DELTA PLCs/Controllers I know of compatible with CODESYS are AX-3 and AX-8 series. You will need to install the proper packages, though. Cheers!

Apparently my construction will not work as any of the sub-types are not be able to accept any (further) value-initiation. Ie: string_item : log_data_base := (string_value := 'test', val_type := STRING_); is not eq to (the string_value will not be assigned): string_item_2 : log_data_string := (string_value := 'test'); Because effectively for the compiler this is eq. to a "double" assignment where the compiler sees only the first assignment (my guess). string_item_2 : log_data_base := (val_type := STRING_) := (string_value := 'test'); Im not sure this should be treated as a bug, but it would surely be nice to be able to use this construction (compiler is 3.5.20.40). Anyone see any other alternative for solution (other than 4 complete STRUCTS with all fields individually defined)?

You can consider using OR_ELSE: Coils[0] := Coils[0] OR_ELSE (Buttons[0] AND Sensors[0] > 6); https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_operator_or_else.html IF Coils[0] is TRUE, then the rest is not relevant anymore and doesn't have to be evaluated anymore. PS, there is also an AND_THEN https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_operator_and_then.html

Interesting, thanks! Didnt know about ANY before, and will sure find a use-case for it. Im not sure it will help me here though, it seems to me that an ANY will not accept a string assignment? I actually think that the "ALIAS" should work, that was a hard found error. I had a fair bit of scratching my head looking for misdirected pointers before I understood what was (not) happening. I will use the work-around of individual structs instead.

Post by timvh on Problem Reading Registers via Modbus from non Codesys device
CODESYS Forge
talk

According to the documentation: https://wiki.teltonika-networks.com/view/RUT956_Modbus You need to create a Channel to read 2 registers from address 143 to get the lattitude. It doesn't specify if you need to read it as a Holding Register or as an Input Register. You could try both. So in the Teltonika router, you need to enable it as being a Modbus Server. Then in CODESYS add an Ethernet Adapter, then a Modbus Client (Master) and to the Client (Master) add the Modbus Server (Slave). Set the IP address and add the Channel. The please consider that CODESYS doesn't update any variables when they are not used in the application. In the I/O mapping tab of your I/O configuration, you can set the "Always update" to enabled.

Thanks for your responses. I like to write the leanest possible code that I can because it makes it much easier to read/maintain/debug. OR_ELSE is what I was looking for. I wasn't sure if CodeSys short-circuited evaluation and I didn't realize this operator existed. Thanks!

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
