Model examples

We have a very well furnished laboratory available, where our programmers can perform debugging of the subparts of SW projects including very complicated applications. We can take advantage of the possibility of the simulation of most needed tasks, thus ensuring the maximum preparation of the SW project already in the office. This reduces to a minimum the programmer´s time spent in the development of a PLC on the assembly site and at the end user´s place.

ELECTRIC LABORATORY-an example of simulated tasks including tests

Basic test tasks:

1. communication with the UNIDRIVE SP converter using analog signal and control from the converter terminal board.
2. communication with the converter using PROFIBUS-DP (instead of analog request, now – digital entering the level of revolutions using the network in combination with control of the converter from the terminal board – start, locking signals).
3. electronic shaft – position coupling: motor+position sensor controlled by entering the desired position from the external angle sensor. The desired and true angles of the motor shaft are to be displayed using MP277 (OP77B).
4. putting into service of the communication with remote inputs from TURCK company (SDPB-0800D-0007).
5. turning the drive through the set angle – enter the angle, confirm and display on the panel MP the true angle through which the motor shaft will rotate. Evaluate the difference (the difference between the desired and true values).
6. motor speed setting by entering the number on the panel MP277 (OP77B), communication with the converter – see Point 2.
7. diagnostics – on the panel MP277 create a table with a possibility to monitor the actual state of digital inputs and outputs.
8. error message display in case of failure (create an error message database).
9. status message display when requesting to signal the actual operations.

Extended test tasks-EnDat, SSI communication, positioning, drive link with admeasurement:

10. communication of the absolute single-speed encoder (EnDat) with the UNIDRIVE SP converter; by means of SM – universal modul plus convert data to the TTL signal which is to be brought to the FM351 position card of the S7-300 PLC; process the data and display the actual position on the HMI panel.
11. communication of the absolute single-speed encoder (EnDat) with the UNIDRIVE SP converter; transfer and process the data by means of SM – Profibus DP; and display the actual position on the HMI panel.
12. communication of the absolute single-speed encoder (SSI) with the UNIDRIVE SP converter; by means of SM – universal modul plus, transfer the data in the SSI format to the input of the FM351 position card of the S7-3000 PLC; process the data and display the actual position on the HMI panel.
13. communication of the absolute single-speed encoder (SSI) with the UNIDRIVE SP converter; using SM – universal modul plus, transport the data in the SSI format to the input of the FM351 position card of the S7-300 PLC; process the data and make a position link – the desired value is set on the HMI panel and, after acknowledgement, automatic positioning to the desired value is performed. Simultaneously the actual value and deviation (difference) are displayed on the HMI panel.
14. communication of the absolute single-speed encoder (SSI) with the converter UNIDRIVE SP; by means of SM – Profibus DP, transfer and process the data, and display the actual position on the HMI panel
15. communication between the absolute single-speed encoder (SSI) and the UNIDRIVE SP converter; using SM – Profibus DP, transfer the data to PLC S7-300 and process them; then carry out a position link – the desired value will be set on the HMI panel and, after adknowledgement, the automatic positioning to the desired value will be performed; the actual value and the deviation (difference) are simultaneously displayed on the HMI panel.
16. simulation of the absolute multi-speed encoder (SSI) by means of an evaluation module (SM – universal modul plus) being permanently fed by a back-up power supply.
17. monitoring the position by means of a safety PLC module PNOZ ms1p and transfer of the actual position into the control system SIMATIC S7-300 using PROFIBUS-DP; then make a position link – the desired value will be set on the HMI panel and, after acknowledgement, the automatic positioning to the desired value will be performed; the actual value and the deviation (difference) is simultaneously displayed on the HMI panel..

22. preparation of visualization screens (unified profile) for possible submission to the customer for approval of the structure of screens (by means of SW CONTROL TECH)
23. database creation (processing of desired displayed data for the DB application) for possible transfer to a higher-level control system.

25. teleservice of a PLC by means of connection of the control system to the ETHERNET network, monitoring using the Ethernet interface
26. communication with a PLC from the other manufacturer (KOYO DL206) using the ETHERNET
27. electronic shaft by means of supplementary converter cards and autonomous control directly by the MASTER converter. Determine the amount of a deviation of both drives and display it on the MP277 panel. Also display the entering request and compare it with the true position of both drives.
28. electronic shaft by means of S7-300 PLC – the link is controlled and monitored by using a PLC; display the true position evaluation of both drives on the MP277; then display the entering request (2 variants: the angle of rotation entered by means of an IRC or by means of a digital value which is entered from the keyboard of the visualization PC and MP 277 panel) and compare it with the true position of both drives; create more program compositions and select the solution with the smallest position deviation between the two drives; evaluate graphically individual solutions on the screen of a process PC.
