My guess is that's a STRING, not an INT type. And it's 128 bytes, not bits

I have found the solution, the CmpEventMgr version has to correspond with the 3sLicense version.

which plc type do you try to add? Unique serial numbers of the plc are mandatory too.

why not simply converting data type UINT to INT? Then avoid negative values with ... := MAX(0 , intTest); Good luck!

Post by eschwellinger on License problem gateway ^{CODESYS Forge talk (Post)}
most important information are missing: Which CODESYS Version? Which runtime version? Which plc type (manufacturere).. Not all plc manufacturer already support application based licenses. From your pictures I see you have activated 4 axis Motion (which is an applications based license type) does only work on plc's which do support this.

Post by phoward131 on Numpad decimal value requires leading zero ^{CODESYS Forge talk (Post)}
I have noticed on the standard numpad dialog, if a user enters a purely decimal number (ie '.6'), the numpad will not accept the value but gives no indication. One must type a leading zero (ie '0.6') in order for it to work. Is there a way to correct this so that a user can just type the decimal value?

Post by timvh on FB string and naming ^{CODESYS Forge talk (Post)}
Really not clear what you are trying to do, but isn't a Struct enough? So add an object of the type DUT to the Application. Then create a structure TYPE ST_Sensor : STRUCT sName : STRING; uiNumber : UINT; END_STRUCT END_TYPE Then in you application add an instance of this Structure stSensor1 : ST_Sensor := (sName := 'my sensor', uiNumber := 1); or use it like this stSensor1.sName := 'my sensor';

it seems that the device you scan, is not the same type which you have added to the project in CODESYS. Virtual Control is Arm 64 SL so please select this type in CODESYS when you generate a new Application..or right click to the device- update device - virtual Control Arm 64 SL

Hi! I am trying to achieve the same issue. Has there been a solution? I can create the mapping, and map the local variable, but somehow the object does not update. Furthermore, i have an issue where codesys doesn't let me set ReadWrite accesses to the variables in the "Type Mapping" place. The access will simply not be set. Has anyone ran int that issue?

Post by zoppp on Visu Frame-configuration___text will not work ^{CODESYS Forge talk (Post)}
Yup, I've been having the exact same issue. A workaround that was working until Visu 4.8.0.0 was using TextList as the type in the frame configuration and then wrapping the text in quotes when configuring it. Im not sure if it will work with variables and I know it does not work if the type is text.

Post by k2saki on CNC Open Source Project / Can I convert my project to text-files ? ^{CODESYS Forge talk (Post)}
Hi. I published My CODESYS-CNC Project to GitHub and I set it Open Source Software. Here https://github.com/k-s-saki/RPi_CODESYS_CNC My CNC Project is binary file , using FBD for IPO , so I found it is a little bit hard to work with people on GitHub. (diff / merge ) My question is 1) Is it possible to convert my project ( only POUs is also fine ) into text file ? How? 2) Would it be better to rewrite all FBD/LD into ST and copy them manually to text files? Thanks.

Post by manuknecht on Using SMC_MOVTYP.INITPOS without specifying the start position ^{CODESYS Forge talk (Post)}
I am using the object SMC_GEOINFO to generate a trajectory and move a system accordingly using the SMC_INTERPOLATOR function block similar to the sample project CNC10_DynamicPath.project. According to the documentation, the movement type INITPOS does not require a start position in the SMC_GEOINFO object, which is confirmed in the documentation of the SMC_GEOINFO object. When using the movement type INITPOS however, the motion will still start from the starting point defined in the SMC_GEOINFO object (0,0,0 if not specified otherwise). Does someone know how to resolve this or is there an example project that makes use of the INITPOS movement type without specifying the starting point? Thanks in advance!

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.
