Welcome to the TRNSYS Users Forum.
The forum is a place where people can interact and have discussions about different topics involving the use of the TRNSYS software package. Here you can post topics for discussion or questions on using TRNSYS and get advice from other users or TRNSYS experts. This forum is not intended for detailed technical support. Users should contact their distributor’s hotline for such assistance.
Some tips for success on using the forum:
- Follow the Forum Rules posted in Forum Administration.
- There are categories for different types of topics and questions. Post your topic or question into the proper category.
- Before posting a topic or question search the existing topics (and the TRNSYS Users listserv archive) to see if a similar topic or question has already been answered.
- Use a descriptive topic name. Don’t use attention getting subjects, they don’t get attention and only annoy people.
- State the version of TRNSYS and which add-ons your are using.
- Include enough specific details for your topic of question to be answered. Just posting “Why am I getting an error?” without describing the specific error and what you are trying to do when you get the error will not receive a response that fixes your issue.
- Remember when people help you, they are doing you a favor. Be patient, help people out by posting good descriptions of what you need help with, and be polite even if a response does not solve your issue.
- Moderators may edit your post for clarity or move your topic to a more appropriate category.
Message 306.
I have copied some part of the listing file o my project. What does
the FORMAT mean in TRNSYS what should I do to solve these 3 error

I can't say for sure from the information given, but if you haven't edited the .dck file directly my guess is you're using a specified-format version of either the Type 9 data reader or the Type 25 printer with an invalid format specification. The Fortran format specification is found on the 'Special Cards' tab of the proforma. The code (F8.2,1X,F8.2), for example, means read/write 8 digits with 2 digits following the decimal place, then read/write one blank space, then read/write another 8 digits with 2 digits following the decimal place. Unless you have a specific reason for using the specified-format version, I would recommend using the free format versions of the data reader and printer.
As a side note, I also noticed there are some Types shown in the .lst file that are obsolete in Trnsys18. Type 4 has been replaced by Types 156 and 158, and Type 6 has been replaced by Type 138. I would recommend replacing the Types in your project with their updated equivalents, especially if you find you're getting error messages or other strange behavior using the obsolete Types (that might be why they were given 'obsolete' status in Trnsys18!).
Thank for your reply. Unfortunately, I forgot to mention that I had this error when I want to calculate max heat load. On the other hand, this error does not comes up when I perform dynamics simulation. Now I am investigating the Types that you said "obsolete".

I have looked at project file both in TRNBuild and Simulation studio. In my project there is no storage tank usage, so I did not use the Type 4 actually. In simulation studio I used these types; Type9a as a reader, Type25d as a printer, Type65 a and d as a online plotter.

@the-mechanix Thank you for the extra clarification! It helps a lot to know what changed in the project immediately before the error occurred. Can you explain what you did to 'calculate max heat load' - did you add an output from Type 56? Add a new printer? Add an equation block? If you did multiple things (like add an equation block and connect its output to a printer), can you retrace your changes step by step and identify exactly which action initiated the error?
Posting the complete .dck file or the complete .lst file would also help a lot - it's really hard to guess at what went wrong in TRNSYS's read of the .dck file from an incomplete copy of its readout.
