Read/write function block
data
Always note the following when working with function blocks:
• The relevant data is transferred in Intel format. In other words,
the first byte is the low byte (Byte 4) and the last byte (byte 7)
the high byte.
• The maximum data length is 4 bytes. All values must be
transferred in hexadecimal format.
• All 32-bit values are treated as signed values. When transferring
32-bit values, ensure that the appropriate value range is suitable
for long integers, i.e. signed.
32-bit value: –2147483648 .. 0 .. +2147483647
