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

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:

1 2 ... 277 278 279 280 281 282 283 284 285 286 287 ... 328 329
