● A maximum of one function replacement is active per block.
● A block with the function replacement must not contain the following elements:
– M98
– Modal subprogram call
– Subprogram return
– Part program end
● If the multitool slot number is programmed with address MTL for the multitool select with
T = slot number, the T replacement also replaces the MTL address. The programmed
values can be queried in the replacement subprogram using the $C_MTL_PROG and
$C_MTL system variables.
