8 Using the "FB_BGD_TEMPLATE_FlyingSaw()"
8.1General information and instructions
The most important element of the technology template is the function block “FB_BGD_TEMPLATE_FlyingSaw()”. The connected “flying saw” is parameterized and controlled using this block.
In the user program, the block must therefore be parameterized and the block mode
The "FB_BGD_TEMPLATE_FlyingSaw()“ is parameterized as described in Chapter 6.3 Interfaces. When parameterizing (assigning parameter values), basic values of the “flying saw” are defined that normally do not change; for example, the name of the flying saw axis, the starting position, the synchronous position etc. These values may only be changed when the system is at a standstill and changes require a
The individual modes of the"FB_BGD_TEMPLATE_FlyingSaw()“ are described in Chapter 3.2 Operating states of the
8.2Initial state of the "FB_BGD_TEMPLATE_FlyingSaw()"
After a “restart”, the “FB_BGD_TEMPLATE_FlyingSaw()” is in the “disable” state.
Each time that the control is started, “restart” must be run by setting the restart bit in the startup task. (this is realized automatically when using the program startup_SAP() in the UNIT SAP_FS)
This means that the template is transitioned into its initial state and important technology parameters are checked regarding plausibility, if possible adapted, and if not possible, parameterizing errors are flagged to the user at the fault output.
8.3Mode changeover sequence
The functions of the function block “FB_BGD_TEMPLATE_FlyingSaw()” and therefore the functions of the connected “flying saw” are controlled using the various state modes of the block.
The following state modes and status transitions can be called at the block:
