Wireless monitoring

ControLinx allows PLC's to send and receive reports and alarms, anywhere in the world, using a North America-wide wireless two-way paging network. The pager network allows data to be sent at less cost than traditional wireless solutions. A PLC can send and receive wireless e-mail messages up to 500 characters in length. Messages are comprised of both control data and pre-configured text.

TPH monitoring

In-situ wastewater monitoring and analysis for Total Petroleum Hydrocarbons with SCADA control of discharge systems is now possible using FCI Environmental's PetroSense® CMS-4000. One to four probes can be strategically placed in wastewater ponds and streams at a wide variety of sites. Each probe can be programmed with its own alarm level and a dedicated 4-20 mA output. When a probe's output reaches the pre-set alarm limit, a 4-20 mA signal is sent to an existing SCADA system to actuate the appropriate valve. At the same time, there is local alarm notification.

Power supply

In the event of a primary power supply failure on a Series 90™-30 PLC, GE Fanuc Automation's new Redundant Power Supply System (RPSS) switches power to a backup unit without process interruption. The RPSS helps ensure uptime in high-availability applications—such as pumping stations, process lines, emergency generating, and batching. Consisting of a baseplate that supports two power supplies and a redundant power supply adapter, the RPSS is compatible with all Series 90-30 power supplies, CPUs, and I/O expansion bases. The adapter mounts in the power supply slot on any CPU or I/O expansion base.
