Move Memory Cartridge (MOVMC)
Load Label (LDLBL)
The Move Memory Cartridge instruction is used to copy data
between V-memory and program ladder memory. The Load
Label instruction is only used with the MOVMC instruction
when copying data from program ladder memory to V-memory.
To copy data between V-memory and program ladder memory,
the function parameters are loaded into the first two levels of
the accumulator stack and the accumulator by two additional
instructions. Listed below are the steps necessary to program
the Move Memory Cartridge and Load Label functions.
Step 1: Load the number of words to be copied into the second level of the accumulator stack.
Step 2: Load the offset for the data label area in the program ladder memory and the beginning of the
V-memory block into the first level of the accumulator stack.
Step 3: Load the source data label (LDLBL Kaaa) into the accumulator when copying data from
ladder memory to V-memory. Load the source address into the accumulator when copying
data from V-memory to ladder memory. This is where the value will be copied from. If the
source address is a V-memory location, the value must be entered in HEX.
Step 4: Insert the MOVMC instruction which specifies destination (Aaaa). This is where the value
will be copied to.
WARNING: The offset for this usage of the instruction starts at 0, but may be any number that does not
result in data outside of the source data area being copied into the destination table. When an offset is
outside of the source information boundaries, then unknown data values will be transferred into the
destination table.
