Using Numeral Memory Table Entries
Any numeral memory table entry can be specified as an operand. When a nu-
meral memory table entry is specified, the number of words used in the calcula-
tion or the number of words stored as the calculation result depends upon
whether words are allocated to the host.
Words not allocated:
The operands/calculation results are treated as 2-word data.
Words allocated:
The operands/calculation results are treated as 1-word data if 1 word is allo-
cated or 2-word data if 2 words are allocated.
Using PC Addresses
Words in the following data areas of the host (PC) can be specified as operands
or calculation results.

*1: LR 00000 to LR 00199 are converted to CIO 01000 to CIO 01199.
*2: The EM Area is supported only by the C200HX/HG/HE(-Z)E PCs.
Since words in the Auxiliary Area of the CVM1 and CV-series PCs is allocated to
system functions, and it cannot be used for purposes other than system use.
Timer and counter PVs cannot be specified directly. Use numeral memory table
entries when using timer/counter PVs.
The range of each memory area differs according to the PC. Refer to Appendix D
PC Memory Maps on page 435.
When a memory link is used, any PT memory address (0000 to 9999) can be
specified.
When a PC address (PT memory) is used, the number of words used in the cal-
culation and the number of words stored as the calculation result are specified
with the data length. The data length specification is the same for all operands
and results of a formula.
