A free TLI (TOPDOC Loadable Instruction) which allows the saving (write to disk) and loading (read from disk) of a block of data table words to a text file or a compressed binary file is now available from our Knowledge Base. The user guide and sample ladder logic are included in the zip file.
These instructions can be used in many ways. Two examples:
- If multiple machines use the same logic but with different data, the machine specific parameters can be stored in separate files and then loaded when SoftPLC first starts up. This allows the SoftPLC *.APP (application files) to be identical, including the initial datatables.
- Prior to machine/process start-up or shut-down you can save/restore critical or retentive data table values.
(This is an enhanced version of the FloatDisk TLM which only worked with floating point data.)
