Using leading-edge wireless sensor networking technology the RS485 wireless connection offers versatility for industrial use of 1:1 or 1:N. The WS-Z5000A can be easily configured within the software enabling the user to easily adopt the WS-Z5000A into a wide range of different RS485 wired protocols.
Crossbow Japan, who has been supplying customized wireless energy solutions to the Japanese market for several years, has now expanded the flexibility of its solutions with the introduction of the WS-A5000A for equipment requiring RS485. This system is a cost-effective solution for users in industries faced with wiring costs and line noise problems. The need for a solution that quickly and easily facilitates the multi-point digital system is here. MEMSIC/Crossbow-Japan's expertise in sensing and wireless network solutions have shaped WS-Z5000A and launched an advanced system for smart and effortless industrial links.
Small Node - Versatile Functionality:
A cigarette box size wireless node offers the functions of a master and slave device interface, which can be configured by the software. Up to 100 nodes can be used in each system, and bind configuration is possible so that the plurality of the RS485 equipment can be connected to each node. The distance between each node can extend to over several hundred meters with each node automatically relaying data from other nodes (multi-hop) while determining the optimal path for data transfer.
No change on existing equipment software:
Using the configuration software, the WS-Z5000A can be adjusted to a wide range of wired protocols, therefore it is not necessary for existing RS485 equipment to change software, making the conversion to a wireless system transparent.
Combining wireless and wired solutions is possible:
One issue with any wireless system is the possibility of a radio propagation obstacle. The WS-Z5000A has solved this problem by enabling a partly wired network. Now one system can consist of several sub-wireless-systems, which are inter-connected by wires in case there are radio obstacles within the installed facility.
Robust Mesh Network:
Traditional wireless RS485 often uses fixed routing, therefore any radio path is a critical path. The proprietary Xmesh radio protocol is a self-forming / self-healing wireless mesh network with ad-hoc multi-hopping capabilities. Therefore if any path becomes unreliable, the network will automatically find a new, better path to stay in reliable multi-point communications. MEMSIC/Crossbow-Japan, being a pioneer in wireless mesh networks, has proven the robustness of Xmesh through deployments of wireless energy systems in energy, storage, factory maintenance, and other various applications, of which over 30,000 nodes are steadily working today. The WS-Z5000A uses IEEE802.15.4 standard, 2.4GHz radio.
The WS-Z5000A has numerous intuitive features that facilitates the ease in installation.
- RS485 line connection is easy to install by simply inserting lines into the push-in terminals.
- Radio link quality is always shown by visible LEDs.
- Packet communications to/from the equipment and to/from another node are indicated by LEDs.
- Node ID, Group ID, and radio channel are selectable by switch, enabling these parameters to always be accessible.
- Mounting can be done by screws, hooks, or magnets.
The system is priced competitively and will be immediately available for purchase in April 2010. Sales inquiries may be directed to email@example.com.
