The actual upper limit of the block number (DB) depends on the current PLC CPU. See section "Key
PLC CPU data for 810D, 840D".

above FCs and DBs can be used provided that the machine to be configured is not a turning
machine with a maximum of two axes and one spindle. If your machine is of this type and if
you might require conventional operating methods in addition to CNC functions, then you
should not use the FCs and DBs above.

ShopMill is an operating system for 2 1/2D milling machines in the workshop environment.
The above FCs and DBs can be used provided that the machine to be configured is not a
milling machine for 2 1/2D machining operations. However, if you intend to use your machine
for applications of this type, then the FCs and DBs should not be used.
