Communications: MDS WiYZ

The WiYZ Gateway is a powerful and flexible device facilitating wired and wireless connectivity to host systems and Enterprise
networks. The WiYZ Gateway supports up to 4 wireless connectivity options for bridging communication between Mesh, Cellular, WiFi and MDS wireless.

The WiYZ Gateway establishes and maintains the ISA 100 mesh network. It also collects data from WiYZ Remotes. Data can be locally stored on the gateway in between transmissions to Enterprise networks resulting in significant savings in cellular communication costs. Alternatively, the gateway supports Modbus for direct polling of sensor and I/O data in real time. The WiYZ Gateway operates as a multi-device hub and bridges IP/Ethernet and serial communication (either wired or wireless) anywhere, between remotes, controllers and PLCs and host systems.

Configurable data transmission periods

Storage of time stamped data in between data transmissions

Security implementation including encryption and password access

Use the web based WiYZ Device Manager for convenient, intuitive configuration and maintenance of WiYZ devices. Device Manager is resident in the WiYZ Gateway and can be accessed via the Ethernet port or over the air via any of the backhaul options. The WiYZ Device Manager provides a comprehensive set of tools and utilities such as configuration wizards, device profiles for repetitive configuration tasks and utilities for saving device configurations and upgrading firmware.

Monitor network status and healtht

Use the MDS WiYZ I/O Extension feature to regenerate I/O signals at meters, RTUs and controllers when direct wiring is too expensive or impractical. Gas wellhead pressure values can be monitored by a WiYZ remote located at the wellhead and regenerated by another WiYZ remote into an RTU or Flow meter.

Use WiYZ to measure pressures at a gas wellhead

Connect pressure instruments or transducers directly to a WiYZ Remote

Transmit pressure values to a WiYZ remote at RTU or Flow meter

Regenerate the pressure values as 0-5 V or 0-20 mA signals to RTU

Connect 1-2 Analog and 1-2 Digital signals per remote

Use WiYZ Remote’s internal battery power at locations without power

Eliminate need to run signal wire between wellhead and meter site

Collect process data from remote assets using IP/Ethernet to local PLC or controller for monitoring and control applications where it is cost prohibitive to run signal wire or when power is unavailable. Use WiYZ to directly connect sensors, transducers or I/O from instruments and meters. WiYZ Remotes automatically form a mesh network around obstructions to the WiYZ Gateway.

Use WiYZ to automatically create a mesh data acquisition network for remote assets

Collect level, pressure and status data from remote devices and send to Gateway

Connect PLC or Controller to WiYZ serial or IP/Ethernet port

Use Modbus to poll data collected at WiYZ Gateway

Use WiYZ Remote battery power at locations without power or DC power at both Remote and Gateway

Use WiYZ to power transducers and instruments

When Operations centers and Enterprise networks need long range access to remote sites, use the Cellular infrastructure or MDS eNET option. The WiYZ Gateway operates not only as the access point to the MDS Mesh network, but also supports WiFi for local drive-up data access.

Collect data from WiYZ gateway using Modbus TCP polling

Transfer data that is logged and timestamped in the Gateway via ftp to host systems.

Use the WiYZ Gateway to create a local IP/Ethernet network for other metering devices and controllers

Use GSM/GPRS, CDMA or MDS eNET to communicate with remote WiYZ networks

Use WiYZ for drive up WiFi access to remote data and network

When a utility uses WiFi at a substation to collect data from IEDs or RTUs and monitor status/condition information the WiYZ Gateway can operate as the WiFi access point to bridge wireless Ethernet and serial data onto the Cellular network or private MDS eNET network. The WiYZ Gateway also supports wired Ethernet and serial connectivity to interface other devices and systems.

Use the WiYZ Gateway to bridge WiFi enabled IEDs or controllers onto cellular infrastructure or IP/Ethernet hub

Optionally connect Ethernet and serial devices to the WiYZ Gateway

Use WiYZ Remotes to monitor other substation status points

Use GE MDS eNET to monitor other devices remote from the substation

When process facilities need to automate data collection from remote assets, metering devices and controllers WiYZ has the versatility not only to form a mesh network around obstructions and interference but also to provide wireless serial and IP/Ethernet connectivity. The WiYZ Gateway can operate as a WiFi remote for connection to an existing WiFi network or create a MDS eNET network for a comprehensive network infrastructure.

Collect data from multiple WiYZ Gateways and Remote clusters monitoring status, pressure level and temperature parameters

Provide IP/Ethernet and serial communication to remote controllers

Bridge remote data onto facility WiFi networks

Use GE MDS eNET to for license free communication to plant control and monitoring systems
