Function block library and Functions
Inside GF Project VX Code PLC development environment are available a set of libraries.To add a library to the PLC project click on “Project” and then “Library Manager”. Here there is the list of the available libraries.
Libraries are typically of 4 types:Standard for 1131 programming languagesGeneral functionality (Gefran)Target specific (Gefran)Specific functionality (Gefran)Creating a new PLC program the libraries of type 1,2 e 3 are automatically included.Libraries of type 4 are present and included in a “documentation only” version; to use the functional original version users has to request them separately.The Gefran Function Block library developed to manage special control functions. The library contains functions such as PID process control, characterisation of analogue variables, and system variables management.
