HEIDENHAIN SHB Data Interfaces for HEIDENHAIN - Manual (Page 42)

April 2010 6 – 43
Machine parameter calculation
Examples: MP 218 (5010.1) - MP 221 (5010.4) and MP 224 (5010.5)
MP 218 (5010.1) = 17736
The LSB must correspond to the transfer program.
("Change identifier" in FDE program)
X (88) - User parameter (general) ME mode
H (72) - Programs in HEIDENHAIN plain language
D (68) - ISO programs
P (80) - PLC programs
M (77) - Machine parameters
S (83) - Non-linear compensation table
The MSB must correspond to the transfer program.
("E" is prescribed in the FDE/TNC program.)
MP 219 (5010.2) = 16712
The LSB can be selected as in the above example; however, it must be the same for both
machine parameter and identifier.
The MSB is "A" as in the FDE/TNC program.
MP 220 (5010.3) = 279
SOH and ETB are fixed for the FDE/TNC program. Otherwise a substitute character can be
selected which must match the data transfer software.
MP 221 (5010.4) = 5382
ACK/NAK is defined for the FDE/TNC program; otherwise a matching substitute character can
be selected in the data transfer software.
