    If the Professsional Developer Edition (which includes the Test Manager) is not supported by Schneider, then an option is to use the Open Source Unit test framework. See: https://forge.codesys.com/lib/counit/home/Home/

    Thank you, I will try it!

    Hi, We are investigating available libraries and frameworks for automated PLC unit testing in Schneider EcoStruxure Machine Expert. Specifically, we are looking for: Assertion libraries or test frameworks compatible with Machine Expert CODESYS‑based solutions that are not TwinCAT‑specific Any official or community‑recommended approach for unit testing FB/FC logic offline We have found several open‑source examples, but many appear to be TwinCAT‑dependent and therefore not compatible. Are there any...

    You are welcome. Also note, that it's valid only if you modbus-device use same real/float value representation (IEEE 754). That's true for most of systems. But some devices may have other representation, such as integer + position of the decimal point, for example 123.456 is integer = 123456 and position = 3 Also note, that, ones again, depending on endianess of each system, you may also need to swap not just words, but bytes. TYPE u_Real : UNION rVal:REAL; wVal:ARRAY[0..1] OF WORD; bVal:ARRAY[0..3]...

    First, if you don't need to change conversion rules in runtime, take a look at "Unit conversion" module (Application -> add object -> UnitConversion). You can specify there biderectional conversion with different units, limits and so on. Second, since MODBUS don't have "real" types but only general 16-bit registers and Real is 32-bit, generally you need a byte-was conversion Real <> two Words. Note, that depending on the devices on both sides, there are two options: Real-> Word1, Word2 or Real->...
