Chapter 6 Internal Memory
„ Internal Register (R/W): $
Word access: $n (n: 0~65535)
Bit access: $n.b (n: 0~65535, b: 0~15)
Delta DOP series HMI provides 65536 16-bit internal registers ($0 ~ $65535).
„ Non-volatile Internal Register (R/W): $M
Word access: $Mn (n: 0~1023)
Bit access: $Mn.b (n: 0~1023, b: 0~15)
Delta DOP series HMI provides 1024 16-bit non-volatile internal registers ($M0 ~ $M1023).
„ Indirect Address Register (R/W): *$
Word access: *$n (n: 0~65535)
Indirect addressing register is the register stored in the range from the address to the internal register.
The user needs to get the address from $n and then get the value stored in this address.
*$n =
For example, if $n = m; $m = X; then *$n = X. (the value of m cannot exceed 65535)
„ Receipt Number Register (R/W): RCPNO
It is 16-bit register that is used to designate the receipt group number. The minimum receipt group
number should be 1 and the maximum group number is determined when editing the receipts.
PLC upload/download will read/write a group of recipe according to the setting of recipe number
register. The length of each group of receipt is determined when editing the receipts.
Delta DOP series HMI provides a space of 64K Words max. for the user to store the receipts.
„ Receipt Register (R/W): RCP
The receipt length is L and the receipt group number is N.
Word access: RCPn (n: 0~NxL+(L-1))
Bit access: RCPn.b (n: 0~NxL+(L-1), b: 0~15)
The recipe register is used to save the recipe that download from HMI after finishing ScrEdit.
There are two methods to read/write these registers:
$n m
X
