for field technicians to manually inspect valves for maintenance.

Another wireless product, OneWireless R120, features a redundant wireless system gateway (WSG), a critical prerequisite for wireless process control. The new WSG manages data between wireless field instrumentation and the plant’s process control network (PCN). It serves as a backup gateway to ensure that data is always delivered even if the main gateway malfunctions or fails. Paired with existing OneWireless redundancy features, this approach creates the first industrial wireless system with complete hardware and radio-frequency redundancy from the field instrument to the PCN connection. Additionally, unique failure recovery features help prevent data loss, and the network can recover in less than two seconds from any field hardware failure.

OneWireless can accommodate multiple communication protocols and thousands of field devices on a single network to help improve overall plant safety, reliability and efficiency. Each gateway can support up to 100 transmitters, and a single OneWireless server can support up to 40 gateways.

New OneWireless products now ship with OneWireless R120 software or firmware.  Any existing OneWireless devices installed at user sites can be easily upgraded by an over-the-air software update to support the new functionality while supporting current investments, HPS says.

Touch for control

Honeywell also released a touchscreen operator interface for its HC900 Control Systems. The Honeywell 900 Control Station is a panel-mounted interface available for all new HC900 installations. It also can be retrofitted for existing, compatible systems.

The new operator interface, featuring a 10.4-inch color display touchscreen, introduces enhanced graphic features designed to reduce set-up time and simplify operation while improving security and versatility in the field.  Pre-formatted displays, custom graphic tools, plus more than 4,000 pre-built process graphic objects make it easy for system designers to create color graphic touchscreen displays that schematically symbolize the layout and functions of the process, facilitating operator acceptance. The interface also helps simplify process changeovers by allowing operators to select from previously stored recipe variables, setpoint programs, setpoint schedules and sequences.
