Searching blocks containing G functions. EJEC G search
When restoring the history of the program, the CNC reads it up to the set block activating and
canceling the "G" functions that reads along. Likewise, it sets the feedrate and spindle speed
conditions of the program and calculates the position where the axes should be.
The M, T and S functions are not output to the PLC, but they are memorized so when the last block
is reached, the CNC shows a list of the conditions that the CNC must have assumed by the history.
Once the simulation is over, the user can restore the M, S, T functions:
A. In the order in which the M, S, T functions were simulated by pressing <EXECUTE MST> and
then [CYCLE START].
B. Pressing the softkeys <TOOL INSPECTION>, <DISPLAY MST> and <MDI>, in this order, the
user can execute the desired blocks in any order he wishes.
The screen shows a list of the M, S and T functions (one per line and in simulation order) bearing
the following in mind:
• It shows the M functions of the history bearing in mind that some M functions may cancel others.
• If there is a second spindle and M functions a programmed that refer to that spindle (M3, M4,
M5, M19, M41-44), they will not cancel the ones equivalent to the first spindle. Also, when
restoring these M functions, it first restores those of each programmed spindle G28 or G29.
• When it receives an OEM's M function and then it receives the same M function, the older one
disappears from the list.
• It displays the last T function programmed as well as the last S function programmed.

search
When restoring the history of the program, the CNC reads it up to the set block activating and
canceling the G functions that reads along. Also, it sets the feedrate and spindle speed conditions
of the program and calculates the position where the axes should be.
The M, S and T functions are executed and output to the PLC.
If in any of the two block searching methods the program that contains the searched block is stored
in a hard disk, Ethernet or DNC, the bottom of the screen can display the line being simulated at
that moment. This information gives an idea of how much is left to reach the block.
Warning: This block searching method is less suitable than the previous one especially when not using
safety mechanisms at the PLC. If the tool is not positioned correctly in the tool changes, it could cause
collisions.
