Try OSCAT_BASIC and Function DW_TO_REAL. DWORD_OF_BYTE my although help. The Lib is open and free. It is not necessary to add this Lib, you can use/copy the source code just to get an idea.

Hi Tobthi, Do you have the eds file of the camera? I usually load first the eds file and then add the device to the Ethernet/IP scanner.

Only idea I have is that new textlists are not loaded with an online change. When you add them, maybe you always have to do a full download first.

Post by full0pullpolen on Device User Logon ^{CODESYS Forge talk (Post)}
The following guide describes how you can adapt the user management for the first time in a project. It deals with the definition of a user and a group to which he belongs. Requirement: the project for which the user management is to be set up is opened. There is no adapted user configuration yet. Select Project Settings ‣ Users and Groups and then the Users tab. The user Owner is already created by default. Click on Add. ⇒ The dialog box Add User appears. Enter a login name, for example ‘Dev1’, and a password. Leave the option Activated activated. Click on OK. ⇒ On creating a group for the first time, CODESYS now requests you to authenticate yourself to perform this action. In this case, enter ‘Owner’ as the current user. Do not enter a password, just click on OK. The user Dev1 appears in the list and is automatically a member of the group 'Everyone'. Change to the tab Groups, in order to add the user to a new group. ⇒ The groups Everyone and Owner have already been created. Click on Add in order to open the dialog box Add Group. Specify at least one name for the new group, for example ‘Developers’. Activate the checkbox next to the entry User ‘Dev1’ in the field Members. Click on OK. ⇒ The group Developers now appears with has user member 'Dev1'. Switch to the Users tab. ⇒ The user Dev1 now appears as a member of the groups ‘Everyone’ and ‘Developers’.

Post by solidlogicguy on Little endian to Float from Modbus RTU ^{CODESYS Forge talk (Post)}
Hello, I got a device from which I require to read values from I am using a WAGO PLC 750-8212 and I am communicating through Modbus Master FUNCTION BLOCK from library WagoAppPLCModbus in Codesys 3.5 to this device. I already receive data from the device that is a CVM to monitor voltage from a fuel cell. The technical support of the company that makes these devices says that the data is sent in little endian form. And I want to convert it to a float value. The tech support sent me the next instructions of how to do it but I am new using codesys, so any advice or help I will really appreciate so much. Message from tech support: The process is complicated, better to do it with already implemented library in the language/program you use. Basically the process should be next: To convert the two Modbus registers containing parts of a 32-bit float in little-endian byte order to a floating-point number using mathematical operations, you first need to combine the two 16-bit integers (assuming reg1 is the lower word and reg2 is the higher word) and then interpret the result according to the IEEE 754 standard. Given: - Register 192 (reg1) = 4096 - Register 193 (reg2) = 14884 Step 1: Combine the two registers. Since we are dealing with little-endian byte order, reg2 is the high word, and reg1 is the low word: combined = reg2 * 2^16 + reg1 combined = 14884 * 65536 + 4096 combined = 975175680 + 4096 combined = 975179776 Step 2: Convert the combined value to binary: combined_binary = '1110101101011100000000000000000' Step 3: Split the binary into IEEE 754 components: Sign bit (1 bit): 0 Exponent (8 bits): 11101011 Mantissa (23 bits): 01011100000000000000000 Step 4: Convert the binary exponent to decimal and subtract the bias (127 for 32-bit floats): exponent = int('11101011', 2) - 127 exponent = 235 - 127 exponent = 108 Step 5: Calculate the mantissa as a fraction: The mantissa in IEEE 754 format is the fractional part after the leading 1 (which is implicit). Therefore, we need to convert the binary mantissa to decimal and add the implicit leading 1: mantissa_fractional = 1 + int('01011100000000000000000', 2) / 2^23 mantissa_fractional = 1 + 18688 / 8388608 mantissa_fractional = 1 + 0.002227783203125 mantissa_fractional ≈ 1.002227783203125 Step 6: Combine the sign, exponent, and mantissa to get the float value: float_value = (-1)^0 * mantissa_fractional * 2^exponent float_value = 1 * 1.002227783203125 * 2^108 Because the exponent is quite large, the resulting float value is a very large number.

Post by royw on Profinet library for C# ^{CODESYS Forge talk (Post)}
Hi, I don't know if I'm in the right place or if it's even possible... I'm looking for a way to address a Profinet device with Record Read and Write from my own PC. I actually only need very few commands to configure our device. This means setting the MAC address and a serial number. We would like to do this from a C# program. Now we are looking for a library or something similar. Since you can do it from Codesys, I thought there might be a DLL or something similar that you could use for this. As I said, we don't want real-time queries of the cyclic data but only record read/write. Does anyone have any helpful hint? Thanks in advance

Post by talpade on WAGO PLC 200 750-8216 Ethernet connection to Codesys 3.5 ^{CODESYS Forge talk (Post)}
Hello, I have the WAGO PLC 200 750-8210. In addition I have downloaded the "WAGO Devices and Libraries 2.0.4.3" and installed the library into the Codesys v 3.5. I then create a new project on Codesys 3.5 and select the device "750-8216 PFC200 (WAGO)" (which I downloaded from the WAGO library). However when I have connected the ethernet cable from the WAGO device to my computer and on my codesys 3.5 i press "Scan Network" on codesys and it does not detect the device. How can I get it to detect the device? (I have put the ethernet cable from my WAGO to the computer, but it does not show the device).

Post by installwhat on C0077 on one machine but not another ^{CODESYS Forge talk (Post)}
I have a version of codesys 3.5.16 on my local machine and a vm. The local machine has loads of codesys versions and libraries installed etc. I can open the FPosCR_Example_Project_SP16_patch1 project on my vm without any errors. On the local machine I get the error C0077: unknown type IoDrvEthercatLib.ETC_CO_SdoWrite. I can, on the local machine, declare a var of type IoDrvEthercatLib.ETC_CO_SdoWrite and include it in the code without adding an extra error. The problem only seems to affect the library. This is seems more an issue with my codesys set up rather than something with festo. I would like to know the possible causes. I understand most of the library manager features but it's not clear how to find the cause. Thanks

Post by kazuhiro on Problems using MySql Library and SysProcessExecuteCommand2 together ^{CODESYS Forge talk (Post)}
I use fbMsSQL_compact(FUN) of the MySQL Library to write data to the database. There is no problem when writing data using only fbMsSQL_compact(FUN). However, when I try to write data obtained using SysProcessExecuteCommand2 to the database using fbMsSQL_compact(FUN), an error message "Dest server on ip address:xxx.xxx.xxx.xxx and port:1433 is unreachable" appears and writing is not possible. From what I have researched, it seems that writing is not completed in one cycle of fbMsSQL_compact(FUN), and when SysProcessExecuteCommand2 is executed first in the second cycle, the work done in one cycle of fbMsSQL_compact(FUN) is reset. Could you please give me some advice?

Post by andrax on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Ok, with debug you suppress the errors, but that doesn't help you any further. You can find information about the missing drivers here https://forge.codesys.com/forge/talk/Runtime/thread/8981ce928a/ and here https://github.com/stefandreyer/I2C-Multiplex I'll have to have another look at which library you need. But you can easily find out. Create a completely empty project and insert the TCA9548. You don't need the board. Then look in the library and resolve all conflicts If you can compile the project without errors, delete the TCA9548 and insert the ADS1115. The driver should then also run. Small bonus: with the TCA9548 you can expand your network as you wish and use identical sensors multiple times

To prevent ambiguous use of this enumeration value. Let's say another ENUM is available in your project or in another library which has an enumeration value AM_WRITE, then it is not clear which AM_WRITE you want to assign. By this qualified access to the SysFile.AM_WRITE, it is completely clear for the compiler.

In addition to 3.5.19, we also have a 3.5.18 version installed, the library versions of Modbus_TCP_Master and Modbus_TCP_Slave are the same, but more than 10 slave channels can be added in 3.5.18
