 The front-end Runtime (WinPAC) and the Back-end Server (Smart 4 Server) communicate via Ethernet, supplemented by
active Field-bus; the remote I/Os transmit data via RS-485. |
The Front-end Runtime (WinPAC) built-in HMI interface can combine WinPAC with touch screen to replace PLC + HMI
in the field case (Better selection: ViewPAC = PAC + HMI). |
| The Back-end server is composed of a PC running the Smart 4 Server software. |
The I/Os support the high-speed Local bus I/O modules (I-8K Series) and the distributed remote I/O modules (I-87K, I-7K
and M-7K Series). |
With the principles of central management and distributed processing, the back-end server sets up the database center,
constructs the system database and collects system data. |
