Elmo Servo Drive Tested Under Extreme Pressure
Elmo Motion Control has announced that its G-TWI servo drive has passed tests while under extreme underwater pressure. This milestone is important, as typical underwater applications such as Remotely Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs) don’t always allow for a fully-controlled pressurized vessel for servo drives.
The modified G-TWI was tested and verified to operate without compromise at 700 atm, equivalent to -7000 meters below sea level. Operation verification was executed at a dedicated facility lab used for testing high-pressure oil and gas technologies.

Hitachi Category 6 Cable Design
Hitachi has introduced its Drybit category 6 indoor-outdoor cable. Conduit that originates indoors but passes through or under a concrete slab is often subject to water infiltration. Thus, standard plenum or riser rated cables can’t be used in these situations, since water will have a catastrophic effect on both their electrical and physical performance.
The typical solution has been to use outdoor cable in the conduit and then transition to the appropriately rated cable type once indoors. The Drybit Category 6 cable, however, eliminates the time and cost associated with transitioning from outdoor cable to indoor-rated cable.

JVL Drive Profile and ServoStep
JVL has unveiled its CiA402 Drive profile and synchronization for EtherCAT. The EtherCAT module is equipped with two Ethernet connectors and a built-in switch, allowing line, star, tree and ring topology without any extra hardware. The module has several LEDs, letting technicians and operators get a quick status overview. There are also opto-isolated digital I/Os embedded in the module, enabling control of extra sensors without external I/O modules. This minimizes the number of devices on the net and reduces cable costs.

Rockwell AI Control Module
Rockwell Automation has released an AI control module to improve industrial production. The FactoryTalk Analytics Logix AI module, formerly known as Project Sherlock, uses artificial intelligence to detect production anomalies and alert workers so they can investigate or intervene, as necessary.
Many existing analytics technologies require expertise in both data science and industrial processes, but this add-on module for ControlLogix controllers reduces that burden by doing the job of a data scientist. It fits directly into a control chassis and streams controller data over the backplane to build predictive models. It can continuously monitor a production operation, detecting anomalies against its derived understanding.
