Abstract

System containing an observation and/or operator'"'"'s unit (OP) displaying and/or presenting process data (SPC3), and a projection unit (PPC) generating a projection data record (SPC1) which can be loaded into the observation and/or operator'"'"'s unit via a data transmission link (DU1). The projection unit includes a first component (M1) which forms a differential data record (SPC5) when a projection data record (SPC1) is modified. The differential data record (SPC5) can be transmitted to the observation/operator'"'"'s unit. In addition, the observation/operator'"'"'s unit includes a second component (M2) which updates a loaded projection data record (SPC2) with the aid of a transmitted differential data record (SPC6).

Claims

1. System for at least the visualization of technical process data, comprising:

a) a first transmission link for data (DU1),

b) at least one industrial observation and/or operator'"'"'s unit (OP) for displaying and/or specifying process data (SPC3), and

c) a projection unit (PPC) for generating a projection data record (SPC1) which can be loaded via the first transmission link (DU1) into the observation and/or operator'"'"'s unit (OP), for at least influencing the display and/or the specification of process data (SPC3), wherein;

the projection unit (PPC) comprises first means (M2) which form a differential data record (SPC5) when a projection data record (SPC1) is modified, and said differential data record can be transmitted to the observation and/or operator'"'"'s unit (OP) via the first data transmission link (DU1), and

the observation and/or operator'"'"'s unit (OP) comprises second means (M2) which update a loaded projection data record (SPC2) with the aid of a transmitted differential data record (SPC6).

2. System according to claim 1, wherein the industrial observation and/or operator'"'"'s unit (OP) for displaying and/or specifying process data (SPC3) comprises an operator panel.

3. System according to claim 1, wherein the first means (M1) of the projection unit (PPC) comprise a differential data generator (DDG) which, when the projection data record (SPC1) is modified, forms the differential data record (SPC5) by comparing to a stored projection data record (SPC4).

4. System according to claim 3, wherein the projection unit (PPC) comprises a control program (PTC)(ProToolCS), and the differential data generator (DDG) is a part of the control program (PTC).

5. System according to claim 1, wherein the second means (M2) of the observation and/or operator'"'"'s unit (OP) comprise a projection data generator (PDG) which updates the projection data record (SPC2) by comparing a transmitted differential data record (SPC5) to a stored projection data record (SPC7).

6. System according to claim 5, wherein the observation and/or operator'"'"'s unit (OP) comprises a control program (PTR)(ProToolRS), and the projection data generator (PDG) is a part of the control program (PTR).

7. System according to claim 1, further comprising:

a) a second and third transmission link for data (DU2, DU3), and

b) an industrial control unit (SPS) which

b1) exchanges process data (Gx, Sx) with a technical process (TP) via the third transmission link (DU3), and

b2) exchanges process data (SPC3) with at least one observation and/or operator'"'"'s unit (OP) via the second transmission link (DU2) (SPR).

8. System according to claim 1, wherein the first means (M1) for forming a differential data record (SPC5) evaluate modifications to a projection data record (SPC1) in binary form.

9. System according to claim 1, wherein the second means (M2) for updating a projection data record (SPC2) evaluate a transmitted differential data record (SPC6) in binary form.

10. System according to claim 1, wherein a differential data record (SPC5) contains at least binary starting and ending addresses, especially of memory areas.

11. System according to claim 1, wherein a differential data record (SPC5) contains at least partial data in binary-coded form.

12. A system for visualizing technical process data, comprising:

a) a first transmission link for data,

b) at least one interface unit at least either displaying or specifying process data, and

c) a projection unit generating a projection data record which is loaded via the first transmission link into the interface unit, influencing the display or the specification of the process data, wherein;

the projection unit comprises a first component which forms a differential data record when a projection data record is modified, and transmits the differential data record to the interface unit via the first transmission link, and

the interface unit comprises a second component which updates a loaded projection data record in accordance with the transmitted differential data record.
