Shared memory

NOTE

This option is not available for the FP0, FP0R, FP-X and FP-e.

Intelligent units have a shared memory that the PLC or intelligent unit can access. You can display how the shared memory is occupied. You can modify values and write them into the shared memory.

The shared memory is divided into banks. Up to 256 banks (bank 0 to bank 255) can be used. Each bank can contain up to 1024 words (word 0 to word 1023).

Each intelligent unit can store up to 256x1024=262144 words.

Upload from shared memory: Upload…

In order to read values from the shared memory, you need to know the following:

  1. the slot number the intelligent unit occupies. The first unit has slot number 0, the second unit has slot number 1, etc.

  2. the bank number from which the data should be read (bank 0 to bank 255)

  3. the start address, i.e. where reading begins (word 0 to word 1023)

  4. the end address, i.e. where reading ends (word 0 to word 1023)

If you try to read values when the PLC is offline, Control FPWIN Pro7 will attempt to establish an online connection to the PLC. Control FPWIN Pro7 uses the parameters set under Online > Communication parameters... .

NOTE

The shared memory dialog can be opened many times. In each dialog, you can modify a bank.

Open a file: Open...

Modify values

You can display the values in byte, word or double-word hexidecimal format. The byte display also contains an ASCII column.

Via the context menu, you can switch between the overwriting and insertion modes.
