TBCD (R558)
The CNC tells the PLC by means of this 32-bit register, the pocket number in the magazine where
the selected tool is.
If the g.m.p. RANDOMTC (P25) has been set so it is not a random magazine, the magazine pocket
position coincides with the tool number.
This will be coded in BCD format (8 digits).
If no T has been programmed in the block, the CNC will assign a value of $FFFFFFFF to this register.
The T function will always be executed at the beginning of the block and the CNC will wait for the
general logic input AUXEND to be activated to consider the execution completed.
T2BCD (R559)
This register is used when a special tool change has been made (family code >=200) or with
machining centers with a non-random tool magazine (general machine parameter RANDOMTC
(P25).
The CNC tells the PLC by means of the 32 bit register, the position of the magazine (empty pocket)
in which the tool which was on the spindle must be deposited.
This will be coded in BCD code (8 digits). If a second T function is not required the CNC will assign
a value $FFFFFFFF to the register.
The second T function will be sent together with M06 and the CNC will wait for the general logic
input AUXEND to the activated to consider the execution completed.
T 123 = 0000 0000 0000 0000 0000 0001 0010 0011
