The response from this command is:
DLE STX DST SRC CMD STS TNS Data DLE ETX BCC
10 02 0B 0D 4F 00 D4 27 69 00 A0 0F 10 03 86
The first two bytes in data field represent the integer portion, 106 (00-69h), of the setpoint.
The second two bytes represent the fraction portion, 4000 (0F-A0h), of the setpoint.
Example: Reading Multiple Analog Values
The following command reads analog inputs channels 3-9 as integer:

Example: Reading Single Discrete Data
After reviewing the Electrical Schematic for your compressor, you determine that the digital
input for emergency stop push button is located on J4-P5 (Channel 4). The CMC data table
address is ADh for the input in question. Therefore, to read the state of the emergency stop
push button as a two byte integer, the following command is issued:
DLE STX DST SRC CMD STS TNS FNC Byte

The response from this command is:
DLE STX DST SRC CMD STS TNS Data DLE ETX BCC
10 02 0B 0D 4F 00 D6 79 01 00 10 03 49
The data response (01) means that the input is ON, or the emergency stop push button is
pressed.
Example: Reading 16 Bit-Packed Discrete Data
To read 16 bit-packed discrete values for digital outputs as a two-byte integer, the following
command is sent:
DLE STX DST SRC CMD STS TNS FNC Byte

Note that the file number must be 10. The local data file used to store the returned data can
be either bit (85h) or integer (89h) type. The response from this command is:
