Faster, More Accurate Serial Data Collection than Traditional “Pull Technology”

I/O Expandability

The ioLogik W5300 Series of RTU controllers are equipped with a

3-in-1 serial port that supports RS-232, RS-422 and RS-485, making it

more convenient than ever (and saving users money) when connecting

field serial devices� This cellular RTU can also create user-defined

Modbus serial tags, to translate serial data from remote serial meters

and flow sensors into OPC tags� Further, ioLogik W5300 Series can

The ioLogik W5300 can integrate external wired clients via daisy-

chained ioLogik E1200 I/O modules� ioLogik E1200 modules support

simple daisy chaining and cost-free peer-to-peer I/O extensions�

Through the RJ45 Ethernet port, the ioLogik W5300 can support up to

three connected ioLogik E1200 series I/O modules to enforce a flexible

and scalable network expansion that best fits customers’ needs�

also actively update tag data to Active OPC Server, resulting in faster

I/O response times and more accurate data collection than in typical

pull-based systems� Except for its active serial tag functions, the

ioLogik W5300 line of cellular RTUs provides transparent serial tunnel

and Modbus RTU communications for direct connectivity between field

devices and central control systems�

Dynamic IP Assignments

For most cellular solutions, each remote modem as well as the

central SCADA server is assigned static public IP when establishing

bi-directional communication� Yet cellular network carriers charge

higher monthly fees for static, public IPs than dynamic, private ones�

Moxa’s ioLogik W5300 series and patented Active OPC Server allow

users to implement dynamic IP assignments for the RTUs� The ioLogik

W5300 can automatically establish communications with the Active

OPC Server using a fixed IP, and the Active OPC Server™ will receive

and register the ioLogik W5300’s IP address and receive or record tag

updates accordingly�
