Notes:
· All values returned are in big endian format (MSB .. LSB)
· short = signed 16 bit value
· ushort = unsigned 16 bit value
· long = signed 32 bit value
· ulong = unsigned 32 bit value
· float = IEEE 754-1985 single precision (4 bytes)
· When a register address is requested that doesn’t coincide with ProBatch data, a word (unsigned 16 bit value) containing all ones is returned.
· When a register address is requested that starts not at the beginning of a multiple register value (e.g. long or float) , a word (unsigned 16 bit value) containing all ones is returned.
· When a register address(es) is(are) requested that doesn’t include all the addresses of the complete multi-word data (but does start at the beginning) the complete multi-word data will be returned with possibly more than the expected number of data words and bytes.
· A write to a multi-word register that doesn’t address all of the words of that register will result in unpredictable data written to the register.
· A writes to registers will have the data values validated. If any of the values are out of range, the write operation will stop at the invalid data value and return an exception response of 3. The previous valid data values will be written to their corresponding registers.
· A write to a register that doesn’t have write enabled is ignored.
The checksum for register address 1016 is calculated from data which uses the following data structure:
unsigned char Cnfig.StationNum
unsigned char Cnfig.DispenseMode
unsigned char Cnfig.Language
unsigned char Cnfig.Units[0..2]
unsigned char Cnfig.DispenseTol[0..2]
unsigned char Cnfig.TimeOut[0..2]
unsigned short Cnfig.MeterFactor[0..2]
unsigned char Cnfig.RecipeSelect
The checksum for register address 7506 is calculated from data which uses the following data structure:
typedef
{
unsigned long FluidParts[0..2];
}RECIPE;
RECIPE Recipe[0..250];
The following function written in C shows how the checksum is calculated for Register Addresses 1016 and 7506.
unsigned short crc(unsigned char *buffer, unsigned short size)
{
unsigned short CrcReg;
unsigned char Lsb;
unsigned char i;
unsigned char j;
CrcReg = 0xFFFF;
for (i=0; i<size; i++)
{
CrcReg ^= *buffer;
for (j=0; j<8; j++)
{
Lsb = CrcReg & 0x0001;
CrcReg >= 1;
if (Lsb != 0) CrcReg ^= 0xA001;
}
buffer++;
}
return(CrcReg);
}
