Plant Asset Management

In systems with conventional Ex i isolators, the series 9192 ISpac HART-multiplexer is used to digitally connect up to 32 HART-enabled field devices, such as transmitters and control valves to a PC. The PC communicates with the HART-multiplexer via an RS 485 bus. Plant asset management tools, such as AMS, FDM, Fieldcare, PDM and PRM enable the configuration and diagnostics of all connected HART-enabled field devices and the continuous monitoring of process variables and conditions. 

The series 7145 WirelessHART gateway for installation in Zone 2 enables communication between WirelessHART field devices and automation and/or plant asset management systems. The gateway can be individually adapted to the relevant requirements using various additional components. The communication interface can therefore be connected to the series 9721 switches via copper or fibre optic Ethernet cables. The new generation of the gateway offers a redundancy function by means of which the availability of the network is increased – if a gateway fails, the redundant gateway will take over the communication with the network participants.

The series 7145 ISA100.11a gateway provides the option of setting up a network with ISA100.11a-compatible field devices and establishing communication with automation systems. The gateway can be installed in Zone 2. Due to the flexible enclosure concept, the gateway can be easily combined with other components and implemented, e.g. a LWL interface with the help of an additional media converter. 

The series 9468 I/O module of the Remote I/O system IS1+ have integrated HART-multiplexers with which the HART variables are read in cyclical data traffic, with which all other HART information can be read and written via acyclical services and FDT/DTM, for example. In addition to the information from the HART field devices, the Remote I/O IS1+ system provides further diagnostics information on all connected devices as well as about the system itself. All this information is based on NE107. Integrated system monitoring detects potential failures largely independently and warns of downtime up to 12 months in advance. This ensures that maintenance concepts such as "predictive maintenance" can be easily implemented.
