The Status variable contains the current status of the ice machine.
The data type for the StatusEnumeration is defined in 20.4.1.
The LastFreezeTime variable contains the time that was needed for the last freeze cycle.
The EngineeringUnit property of the AnalogItemType has the value s. The value for the EURange property is device-specific.
The LastHarvestTime variable contains the time that was needed for the last ice harvest.
The EngineeringUnit property of the AnalogItemType has the value s. The value for the EURange property is device-specific.
The WaterFillTime variable contains the time that was needed for the last water filling.
The EngineeringUnit property of the AnalogItemType has the value s. The value for the EURange property is device-specific.
The Temperature variable contains temperatures such as ambient temperature, compressor outlet temperature, evaporator outlet temperature, evaporator inlet temperature, etc.
The contents of these variables depend on the device type and device equipment. The meaning of the individual temperatures can be taken from the description of the respective ice machine.
The EngineeringUnit property of the AnalogItemType has the value °C. The value for the EURange property is device-specific.
IceMachineDeviceType describes the composition of the fundamental operational data of an ice machine, which are to apply in addition to the DeviceType.
These operational data enable the current state of the device or its current task to be comprehended and mapped in other systems, e.g. a monitoring database.
The IceMachineDeviceType is formally defined in Table 70.

This data type is an enumeration of the possible operation modes of the ice machine. The enumeration values are defined in Table 71.
Table 71 — StatusEnumeration values
|
Value |
Description |
|
INIT_0 |
Commissioning, started manually (switch on) or automatically (after cleaning) |
|
WATER_PURGE_1 |
Existing water in the tray is flushed out and fresh water is filled for the next cycle |
|
PRE_CHILL_2 |
Precooling of the evaporator for xx seconds during the initial commissioning |
|
FREEZE_3 |
The water freezes on the evaporator to form ice |
|
HARVEST_4 |
Ice is harvested |
|
BIN_FULL_5 |
The state indicates that the ice container is full and that ice making has been stopped |
|
CLEAN_6 |
Ice machine is running through the cleaning steps |
|
OFF_7 |
Ice machine is switched off |
|
SLEEP_MODE_8 |
Power failure detected, system clock continues to run |
|
STANDBY_9 |
State after a temperature sensor error |
|
SAFE_MODE_10 |
Continue with ice making following an error |
|
WATER_OUTAGE_11 |
State with a lack of water |
|
HPCO_DELAY_ACTIVE_12 |
Maintenance state when the overpressure switch is activated and no ice is made for xx minutes |
|
CURTAIN_OPEN_13 |
Curtain was opened because there is an ice slab between the evaporator and the container. |
|
PRODUCTION_TEST_14 |
Ice machine is in the function test mode (at the manufacturer) |
|
SAFE_MODE_PRECHILL_15 |
Like the PRE_CHILL_2 state, but after a SAFE_MODE_10 state |
|
SAFE_MODE_FREEZE_16 |
Like the FREEZE_3 state, but after a SAFE_MODE_10 state |
|
SAFE_MODE_HARVEST_17 |
Like the HARVEST_4 state, but after a SAFE_MODE_10 state |
|
SAFE_MODE_FULL_BIN_18 |
Like the BIN_FULL_5 state, but after a SAFE_MODE_10 state |
