Instrument network architecture

Instrument certification and calibration certificates are included along with the stated environmental conditions that the IPC can tolerate. For small-scale IPC systems, the HDS can be included in the FDS. Figure 25.2 shows a typical architecture of a networked IPC system. 

Today networks are used to connect operation computers of instruments with one or more laboratory computers (with a LIMS). These are connected to higher computers of the organization. Many LIMSs use a client server architecture. For the ordinary user of a LIMS the hardware platform is not important. A LIMS manager has to consider backup, archiving, removal of failures, support, and other aspects. If an efficient EDP department works in the organization, it should operate the hardware, but if there are problems the LIMS manager must be able to cope with them. 

The supervision and control system integrates the main console, secondary console, training console, supervision desk, radioprotection desk, local supervision centres, instrumentation racks containing processing hardware and software, wiring and networking and plant instrumentation Fig 2 4 shows the general architecture of the supervision and control system and its relationship to the reactor protection system...
