Continuous Setpoint Status
Low order bits of bytes 3–4 are set on
to indicate continuous setpoints for
which conditions are being met. Bits are
assigned to setpoint numbers as shown

Use the table at right to evaluate the ASCII character
output for bytes 3 – 12 and determine which of the
low-order bitts are set on.
For example, if the digital output status returned in
bytes 8 – 11 is C, the table at right can be used with
the bit assignments described above to determine
that digital outputs 2 and 1 are active:
• A (byte 8) indicates that DIGOUT 4 (bit 0) is on
• C (byte 9) indicates that DIGOUTs 0 and 1 (bit 1
and 0) are on
• @@ indicates that bytes 10 and 11 are not used
