Addresses

In Control FPWIN Pro7, explicit user addresses should only be entered in the global variables list by assigning addresses to global variables. Using explicit user addresses in the programming editors is unsafe and not recommended with exception of index modifier addresses (see compiler warning).

Two formats are available: FP address and IEC 61131-3 address.

FP address

Format:

• Slot address prefix for unit memory addresses, e.g. S23:UM4A (FP7 only)

  • Slot address specifier S

  • Slot number dd, e.g. 23 of S23:UM1A0

  • Separator ':'

• Double size prefix D only for 32-bit values of words

• FP address prefix:

  • For 1-bit values, e.g. X, Y, R

  • For 16-bit words with bits, e.g. WX, WY, WR

  • For 16-bit words without bits, e.g. DT, FL

• Address offset:

  • For bits in word data "dddX", e.g. 100A of R100A

  • For bits not in word data "dddd", e.g. 1234 of E1234

  • For word data "dddd", e.g. 1234 of DT1234

  • For word data in the unit memory "XXXX", e.g. ABCD of S3:UMABCD

IEC 61131-3 address

Format:

• IEC direct address type prefix: '%'

• Location prefix:

  • I, input

  • Q, output

  • M, internal memory

• Size prefix:

  • X, 1 bit

  • W, 16 bits

  • D, 32 bits

• Area hierarchy number and seperator '.' for the internal memory area M

• Slot number and seperator '.' for unit memory addresses (FP7 only)

• Address offset:

  • For bits in word data "ddd.d", e.g. 100.10 of %MX0.100.10

  • For bits not in word data "dddd", e.g. 1234 of %MX10.1234

  • For word data "dddd", e.g. 1234 of %MW5.1234
