Poll Select Description
20 20 20 21 Controller integrity command used to accept and retain data and provide it in response to
a poll inquiry in an open 4-byte ASCII format with ASCII units.
20 22 Controller version command used to provide a version number following format: AABB,
where AA=SPI assigned version level, BB=vendor assigned version level in an open
4-byte ASCII format with ASCII units.
20 30 20 31 Target supply coolant temperature leaving the unit in a numeric format in °F.
20 32 20 33 Value in conjunction with the process set point that determines the high alarm tempera-
ture in a numeric format in °F must always be positive.
20 34 20 35 Value in conjunction with the process set point that determines the low alarm tempera-
ture in a numeric format in °F must always be positive.
20 40 Process status in a 16-bit format as follows:
0=controlling
1=an alarm is present
2=an alarm affecting the process has occurred (high or low temperature deviation)
3=an alarm affecting the machine has occurred (probe fault or pump fault)
4=the controller has exceeded its over set point deviation
5=the controller has exceeded its below set point deviation.
20 42 Machine status in a 16-bit format as follows:
0=controlling
1=an alarm is present
2=an alarm affecting the process has occurred (high or low temperature deviation)
3=an alarm affecting the machine operation has occurred (probe fault or pump fault)
4=the controller has exceeded its over set point deviation
5=the controller has exceeded its below set point deviation.
20 44 Machine status in a 16-bit format as follows:
0=controlling
1=an alarm is present
2=an alarm affecting the process has occurred (high or low temperature deviation)
3=a sensor error has been detected
4=an alarm affecting the machine operation has occurred.:
20 48 20 40 Machine mode in two 8-bit bytes. When polling 20 48 bit 0 indicated the machine is off. 20
40 bit 0 commands the unit to be turned on or off (on when high or off when low). 20 40
bit 1 is used to recognized the alarm condition.
20 70 Returns the process supply temperature in a numeric format in °F.
20 72 Returns the process return temperature in a numeric format in °F.
