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.

How can I format integer so it would display 001 instead of 1? Is it possible? I couldn't find it in documentation

Post by balazska2 on Position values with integer variables ^{CODESYS Forge talk (Post)}
Hello guys! https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_elem_label.html My question: Could I give an integer variable to the Position records (in the Element list => Position => width / height)? If yes, how? I defined a TEST integer variable with 300 value. I tried to add this variable to the width record (.TEST or only TEST), but if I saved, the value jumps back to 0. Thanks for your help! :)

Post by alexgooi on Modbus writing on value change ^{CODESYS Forge talk (Post)}
The way I usally tackle this is by syncing only words (then you are able to use the FB above). If you then want to write a Boolean simply type it like this. Value[1].0 := Bool1; Value[1].1 := Bool2; Value[1].2 := Bool3; Uints have the same number of bits than a INT/WORD so these ones will work as well (they are only represented diffrently). A Real will work but you will loose some infomration in the conversion. If you want to keep the information you can convert 2 words to a float with a function (for example with the IEEE-754 standard) . In this way the syncing to the server is very simple and in the Codesys Program you decide what part of the word you want to use.

Post by gatto on Read codesys version in the codesys application ^{CODESYS Forge talk (Post)}
hi, i used another way declaration: pApp : POINTER TO APPLICATION; pAppInfo : POINTER TO APPLICATION_INFO; ProjectName : STRING (24) ; CodesysVersion : STRING (15) ; code: //library : // CmpApp // IoDrvEthernet // // Get Pointer to current application pApp := CmpApp.AppGetCurrent( pResult:= 0 ); // Get Pointer to Application information pAppInfo := CmpApp.AppGetApplicationInfo(pApp:= pApp, pResult:= 0 ); ProjectName := pAppInfo^.pstProjectName^ ; //convert codesys version to string CodesysVersion := IoDrvEthernet.UDINT_TO_IPSTRING ( udiIPAddress := pApp^.udiPSVersion ) ; so i think you need to convert your dwVersion in a UDINT and after convert UDINT_TO_IPSTRING

Post by song on How to convert a standard robot program into an excutive list when a robot runs? ^{CODESYS Forge talk (Post)}
Dear Sir, I'd like to learn and try to make robot based on Codesys, is there a FB block or other ways to convert a standard robot program into an excutive list? how codesys explain the robot command instructions on HMI, just like the SMC_NCDecoder used to convert CNC program into a list of SMC_GEOINFO object. Thanks very much! Peter Yan

Post by bjarne-pagaard on Codesys v3.5 Sint to byte ^{CODESYS Forge talk (Post)}
Hi A SINT is a short (signed) integer. It is already only 1 byte - so you should have no problem casting it to a byte like so: bMyByte := TO_BYTE(sintMyShortInt); If you have a regular INT you want to put in 2 bytes - there are a lot of ways you can do this. A Union is certainly one of them. You could have a union with 2 memebers: An array of 2 bytes as one member, and an integer value as another member. Another way would be to look at MEMCPY to put the value into your CAN-message. .. or create a function to take your input value as input, and giving you 2 individual bytes as output. This could be handy if you need to change the byte-order. Integer data types: https://help.codesys.com/webapp/_cds_datatype_integer;product=codesys;version=3.5.17.0 -Bjarne

Maybe try going back to step one and: Var Reg1: WORD; Reg2: WORD; Reg12: DWORD; Value: REAL; end_var // program Reg1:= 4096; Reg2:= 14884; Reg12:= (reg2 * 65536) + reg1; Value:= DWORD_TO_REAL(Reg12);
