The function of bits in C are shown in the following diagram and explained in

more detail below.

15 14 13 12 11 00

Number of items in range (N, BCD)

001 to 999 words or bytes

First byte (when bit 13 is ON)

1 (ON): Rightmost

0 (OFF): Leftmost

Calculation units

1 (ON): Bytes

0 (OFF): Words

C:

Not used. Set to zero.

Number of Items in Range The number of items within the range (N) is contained in the 3 rightmost digits of

C, which must be BCD between 001 and 999.

Calculation Units The frame checksum of words will be calculated if bit 13 is OFF and the frame

checksum of bytes will be calculated if bit 13 is ON.

If bytes are specified, the range can begin with the leftmost or rightmost byte of

R1. The leftmost byte of R1 will not be included if bit 12 is ON.

MSB LSB

R112

R

1

+1 3 4

R1+2 5 6

R1+3 7 8

When bit 12 is OFF the bytes will be ORed in this order: 1, 2, 3, 4, ....

When bit 12 is ON the bytes will be ORed in this order: 2, 3, 4, 5, ....

Conversion to ASCII The byte frame checksum calculation yields a 2-digit hexadecimal value which is

converted to its 4-digit ASCII equivalent. The word frame checksum calculation

yields a 4-digit hexadecimal value which is converted to its 8-digit ASCII equiva-

lent, as shown below.

Flags ER: Indirectly addressed DM word is non-existent. (Content of :DM word is

not BCD, or the DM area boundary has been exceeded.)

The number of items is not 001 to 999 BCD.
