General notes

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 5) and the last byte (byte 8) 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.
