17.2 TemperatureZoneType
17.2.1 TemperatureZoneType Definition

17.2.2 Index
The Index Property gives the number of the zone.
NOTE: If the Property Classification is used, for each temperature zone type the Index may start with 1.
17.2.3 Name
The Name Property represents the name of the zone.
17.2.4 IsPresent
This Property informs the client if the temperature zone is physically present and connected. May be FALSE e.g. when instances for possible temperature zones are created (depending on the capabilities/connectors of the machine) which are currently not used.
17.2.5 Classification
This Property informs the client about the type of the temperature zone. The TemperatureZoneClassificationEnumeration is defined in Table 67.
| Name | Value | Description |
| OTHER | 0 | This value is used if none of the other values below apply. |
| HEATING | 1 | The zone is a heating zone |
| COOLING | 2 | The zone is a cooling zone |
| TEMPERATURE_CONTROL | 3 | The zone is controlled by a temperature control device |
| HOT_RUNNER | 4 | The zone is a hot runner zone |
| MEASURING | 5 | The zone has no heating or cooling, Only the temperature is measured. |
17.2.6 ControlMode
The ControlMode Property indicates how the temperature is currently controlled. The ControlModeEnumeration is defined in Table 68.
| Name | Value | Description |
| OTHER | 0 | This state is used if none of the other states below apply. |
| OFF | 1 | Control is switched off. |
| AUTOMATIC | 2 | The parameter is controlled automatically. |
| TUNING | 3 | Optimisation of the control circuit. |
| STANDBY | 4 | Parameter is controlled to stand by value. |
| OPEN_LOOP | 5 | Open loop control is used. |
| ONLY_MEASUREMENT | 6 | The sensors deliver the current value but there is no controlling. |
17.2.7 Temperatures
The following five temperatures for monitoring and controlling are defined:
| BrowseName | Description | Optional |
| NominalTemperature | Nominal value (absolute) (e.g. 200°C) | No |
| HighDeviationTemperature1 | Maximum value that is in the normal tolerance. A higher actual value may create a warning. Used for quality control. Relative value (e.g. +10°C). | Yes |
| LowDeviationTemperature1 | Minimum value that is in the normal tolerance. A lower actual value may create a warning. Used for quality control. Relative value (e.g. -15°C). | Yes |
| HighDeviationTemperature2 | Maximum tolerable value. A higher actual value may create an alarm. Relative value (e.g. +30°C). | Yes |
| LowDeviationTemperature2 | Minimum tolerable value. A lower actual value may create an alarm. Relative value (e.g. -25°C). | Yes |
17.2.8 ActualTemperature
The ActualTemperature Property represents the current temperature of the Zone.
17.2.9 StandbyTemperature
The StandbyTemperature Property represents the standby temperature of the Zone.
17.2.10 Subtypes of TemperatureZoneType
The TemperatureZoneType has two subtypes to distinguish between temperature zones on barrels and in moulds.
17.2.10.1 BarrelTemperatureZoneType
| Attribute | Value | ||||
| BrowseName | BarrelTemperatureZoneType | ||||
| IsAbstract | False | ||||
| References | Node Class | BrowseName | DataType | TypeDefinition | Other |
|---|---|---|---|---|---|
| Subtype of TemperatureZoneType | |||||
| 0:HasProperty | Variable | Position | 0:UInt32 | 0:PropertyType | M, RO |
The Position Property represents the location of the temperature zone on a barrel. Counting starts with 1 beginning from the feeding. The highest position is at the nozzle.
When instances are created the BrowseNames shall be “BarrelTemperatureZone_<Nr>” (starting with 1).
17.2.10.2 MouldTemperatureZoneType
| Attribute | Value | ||||
| BrowseName | MouldTemperatureZoneType | ||||
| IsAbstract | False | ||||
| References | Node Class | BrowseName | DataType | TypeDefinition | Other |
|---|---|---|---|---|---|
| Subtype of TemperatureZoneType | |||||
The subtype has no additional child elements.
When instances are created the BrowseNames shall be “MouldTemperatureZone_<Nr>” (starting with 1).
NOTE: Each MouldTemperatureZone belongs to a Mould. Numbering starts with 1 for each Mould. That means Mould_1 has a MouldTemperatureZone_1 and Mould_2 has also a MouldTemperatureZone_1.
