*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.
The Auxiliary Area of the CVM1 and CV-series PCs is allocated to system func-
tions, and cannot be used for purposes other than system use.
The range of each memory area differs according to the PC. Refer to Appendix D
PC Memory Maps on page 435.
Storage Type (to Words in the Host)
Specify each recipe data format individually when storing data from the recipe
data memory in the PT to words in the host, or when reading data from words in
the host.
When Storage Type Is BCD
Writing from PT to Host
The binary data in the recipe data memory is converted to BCD data and written
to the host. If the number is negative, the most significant digit in the word is writ-
ten as “F.” (Consequently, if the number is negative, the largest possible number
of digits (integer digits + decimal digits) is seven.
If the content of the recipe data memory exceeds the range that can be handled
by the words allocated in the host, “– (minus sign) + least significant digit” is writ-
ten to the host (refer to explanation below).
Reading from Host to PT
The contents of the words on the host are taken to be BCD data, and are read to
recipe data memory. If the most significant digit is “F,” the contents are taken to
be negative.
If the contents of the words on the host are not in correct BCD data format (i.e., if
the most significant digit is A to E, or if any of the other digits are A to F), the data
will not be read, and the PT recipe data memory will retain its previous value.
When Storage Type Is Binary
Writing from PT to Host
The binary data in the recipe data memory is written unconverted to the host.
Reading from Host to PT
The contents of the words on the host are taken to be signed binary data and are
read to recipe data memory unconverted.
