ADCCP Modifiers
When the address field is greater than 1 byte in length, the last byte must contain an
odd value. An odd value in any byte other than the last byte (which makes the least
significant bit a 1) will cause unpredictable results. You should use the default setting
for this modifier unless some addresses are greater than 1 byte (octet), in which case
variable-length addresses are required.
ADDRESS n value
This modifier specifies the address value (in octal) of a byte in the frame’s address
field. The address value is specified by value, and the byte (octet) into which the
value is to be placed is specified by n, where 0 specifies the first byte and 3 specifies
the last byte.
If AFLD1 has been specified, the address field is 1 byte long, the form of the modifier is
ADDRESS0, and value must have a value from 0 to 254. However, if the address
field is longer than 1 byte (that is, if a value greater than 1 has been specified for the
AFLD modifier), only the last byte can contain an odd value; all other bytes (octets)
must have an even value.
