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.

Hi, I have been working on Codesys V3.5 with PFC200 controller and Can Gateway 750-658. I want to convert the incoming CAN data from bytes into UINT and for outgoing data bytes to UINT. Does anyone has experience with this kind of data? I tried few different ways but it doesn't seem to be working.

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.

You should not use the "open dialog" to change the value. Instead use the input configuration "Write Variable" to change a variable value in the visualization. in the setting of this input command, you can choose the Input type (select dialog).

Which plc type is it: Either use Automationserver to do this or save the project archives instead of projects or use the source dowload function and reopen the application from plc. So you need to chose one of them.
