  1. Function Block Instance error

    I'm using CX-Prog 6.00. I'm actually doing an internship at my school (Last semester of a 3 year career program), so I don't believe there'd be any easy way for me to update to the lastest version, either.
  2. Function Block Instance error

    Thank you Nibroc. Although the problem had fixed itself temporarily when I switched to a slightly older backup, the corruption must have still been there for it came back haunting me today. I then decided to follow your advice and voilà! My problem is fixed... Hopefully forever. Conversions are annoying, I've decided!
  3. Function Block Instance error

    I seem to have fixed my problem by loading a a slightly older (but not enough for me to lose anything) version of my project. Good thing I had a backup... I still don't have a clue why it wouldn't let me use them instances though.
  4. Function Block Instance error

    I'm nearing the end of a project in which a an Omron PLC, CJ1M series, communicates over a ModBus network using a SCU41 card to read/write various data accross the network. However, I've recently come up with a problem that's making all my work seem useless. I have been creating a function block for each kind type of component across the network, be it power regulator or circuit breaker, that way its easy to take a block and move it across a program plus it serves as a black box, you don't need to see what its doing, just the results. However, due to many, many comparison lines I've inserted to map the different data types in each of the network components (aka the program automatically knows wether its looking for UDInt, Floating Point, UInt and gathers the necessary date), I had too many steps and ran out of UM. I therefor changed from a CPU11 to a CPU22, and all should be good. However, I now get an error message "Internal error. Failed to generate Function Block Instance code" which is preventing me from sending my program to the new CPU. Only 1 of my FBs seems immune to this error. Any help?
