Goodtech - Open Process Control System
The Goodtech Open Process Control System is a modular high performance system based on industry standard hardware and software. The system is based on Simatic standard PLC hardware in the S7 300, S7 400 and S7 1500 range. Any OPC client capable HMI system can be used as HMI system. Of course HMI systems using native Simatic S7 communication can be used as well.
When the system is constructed using the Goodtech SmartR/O system, the Goodtech Data Bridge and the Goodtech standard PCS version 4.0 and 5.0 components the system is capable of time stamping messages with a resolution of two milliseconds. The actual time stamping is performed by the 10 units, avoiding communication delays to influence the time stamp resolution. In such an application a high precision time synchronization source is used for time synchronisation of all units in the system. In this system all data is transferred between the PLC system and the HMI system includes time stamps and quality codes.
Engineering of the system is performed using standard PCS7 engineering tools and the functionality of the system is roughly equivalent with the functionality of the Goodtech PCS7 system.
The Goodtech Open Process Control System implements functionality according to NORSOK standards.
