TECT_TEMPZONE_DATA_TYPE

TECT_TEMPZONE_DATA_TYPE (Temperature Zone Data) is a structure, which defines the control words, status words, limits and parameters for temperature zone control process.

It is recommmeded to declare TECT_TEMPZONE_DATA_TYPE as retain variables for power safe. All zones must be declared one after another without break. A zone group must be declared together without break. It is recommended to define an array of TECT_TEMPZONE_DATA_TYPE for one group.

Example:

If there are three groups with group 1, 2 and 3 having 8, 6 and 4 zones, then TECT_TEMPZONE_DATA_TYPE has to be declared or attached into the Function Block TECT_GROUP as follows: In global retain variable as tsZonedata := ARRAY[1..18] OF TECT_TEMPZONE_DATA_TYPE. For group 1 as tsZonedata[1], for group 2 as tsZonedata[9] and for group 3 as tsZonedata[15] as the first zone for respective group.

The structure TECT_TEMPZONE_DATA_TYPE consist of 5 internal structures. These substructures are defined as per function of the parameters.

• TECT_INTERNAL_STATUS_TYPE,
• TECT_MACHINE_SET_TYPE,
• TECT_MACHINE_STATUS_TYPE,
• TECT_PROCESS_SET_TYPE,
• TECT_PROCESS_STATUS_TYPE.
