8 C Language Function Block
In this chapter, we focus on C language function block’s specifications, edition, instruction
calling, application points etc. We also attach the common function list.
8-1 Summary
XD/XL series supports to write function blocks in C language in the Xinje PLC software and
call them where needed. It supports almost all C language functions (compared with XC
series, XD/XL series also supports global variables), which enhances the confidentiality of
the program. At the same time, it can call many places and different files, greatly improves
the efficiency of programmers.
