Post by jinlee on Symbol Configuration ^{CODESYS Forge talk (Post)}
Hi guys, I am working on an old project which using Codesys v2.3 talks to Beijer's screen TA150 (IX-Developer 2.20). Codesys v2.3 is different with 3.5 and Ecockpit. I know how to import the symbols from PLC to HMI for Codesys 3.5 and Ecockpit. However, I do not know how to do it on Codesys v2.3. I know that I can make excel sheet to import and export from the HMI and add whatever I want based on PLC. However, is there any quicker way of doing this? So that I can directly import the symbols (tags) from PLC (Codesys 2.3 to HMI).

Post by rd76065 on Opto 22 Groov PR2 Modbus TCP Master communication ^{CODESYS Forge talk (Post)}
Previously, I have used ModbusEthernet_04 library for Wago for ModbusTCP Master communicational in Codesys V2.3. How to use same communication of similar UDT for Opto22 Groov PR2 PLC in Codesys V3.5 SP20. Can I use OSCAT library - Network -MB_Client or IODrvModbusTCP - ModbusRequest for this requirement? If any other please guide.

Post by tib0r on c2iec - translating C to ST ^{CODESYS Forge talk (Post)}
I was looking for a transpiler from some more widely used general programming language into ST. It was not easy but I found this :) https://forge.codesys.com/tol/c2iec/home/Home/ Does anybody use it for a programm/library of a couple of hundred lines or more? How does one go about using the output? Is there a “converter” into the Codesys IDE? PLCOpenXML? Would there be interest in this? tib0r

This is a consequence of how computers store floating point numbers. 0.1 cannot be exactly represented in a computer. This is not a CoDeSys thing. Here is a link to a converter to show you the exact value that is represented when you use a REAL data type (which is a 32 bit float). https://baseconvert.com/ieee-754-floating-point If you really need to keep track of 0.1 increments. use INT OR DINT and then add 1 each time and assume that there is one decimal place.

Post by sanacfu on looking for v2.3 libraries on v3.5.19 ^{CODESYS Forge talk (Post)}
Hi all, I'm new to Codesys and Wago but well versed in Rockwell. I've been tasked with upgrading old Wago 750-880 PLCs that run Codesys v2.3. All I was giving is the original PLC program in v2.3 and the currently running machine. I've spec out to what I believe is a suitable upgrade, the PFC100 2ndGen, 750-8111. As I'm rewriting this code on the Codesys I can't find the same library functions blocks for ethernet settings PLC functions. Currently I'm working on code to get/set the PLC ethernet IP address and HMI IP addresses from the HMI screen. One other function I'm looking for is a warm reset function to the PLC. When googling for this stuff I see a lot of code not in ladder logic. Are these functions now not available to implement in ladder logic? Where can I get more information on finding and implementing this functions? Do I have to buy a license from Codesys to use these functions? The PLC I ordered should be arriving in 2-3 weeks.
