4-6-9 SYSMAC NET Link Table Transfer (CPU31/33-E Only)
The
SYSMAC NET Link T
able T
ransfer operation transfers a copy of the
SYS
-
MAC
NET Link Data Link table to RAM or EEPROM program memory
.This al
-
lows
the user program and SYSMAC NET
Link table to be written into EPROM
together. This operation is applicable to the CPU31-E and CPU33-E only.
Note When
power
is applied to a PC which has a copy of a SYSMAC NET Link table
stored
in its program memory
, the SYSMAC NET Link table of the
CPU will be
overwritten. Changes made in the SYSMAC NET Link table do not affect the
copy
of the SYSMAC NET Link table in program memory; SYSMAC NET Link
Table Transfer must be repeated to change the copy in program memory.
The SYSMAC NET Link Table Transfer operation will not work if:
• The
Memory Unit is not RAM or EEPROM, or the write protect switch is not set
to write.
• There isn’t an END(01) instruction.
• The
contents of program memory exceeds 14.7K words. (T
o find the size of the
contents of program memory, do an instruction search for END(01).)
SYSMAC NET Link table transfer can only be done in PROGRAM mode.
