| The LonWorks Gateway communicates between a LonWorks network interface on one side and various serial protocols on the other side (e.g. Modbus ASCII / RTU etc.). It allows LonWorks devices to make available their LonWorks variables for PLCs or SCADA. It also makes possible for serial device to act as a LonWorks node.
It is externally powered from 3 pin terminal block and power is isolated from both communication ports. Both the communication ports are also isolated from each other.
Microsoft Windows® based configuration software, Gateway Setup, helps the user to configure Gateway unit. ‘Configuration’ means making the Gateway unit work as per the system requirements. The complete configuration for a unit is termed as ‘Project’. Project comprises of device names, Register addresses, Conditions for block execution etc.
Block may contain information like copy number of Words, Bits etc. from one device to other device and conditions for copy, if any. Gateway transfers data between two devices by execution of blocks.
After the Project is defined, Drivers for required devices and Project should be downloaded. Gateway can now communicate with the connected devices and transfers data between them
System requirements for Gateway Setup Software are:
Programming software is common for the entire Gateway family.

Other Accessories required for the GWY-100 configuration and to
use in actual application:
1. Gateway Configuration / Connecting Cable.
2. Gateway Setup Software .
3. Devices with communication cables.
4. Network Management Tool (Lonmaker) for installation of a node and binding of network variables.
Note : GWY-100 Supports up to 62 network variables. LonWorks Wizard allows the user to configure Gateway for SNVT variables.
We welcome opportunity to develop new / customized drivers for UNVT templates.
Communication ports:
GWY-100 has two communication ports COM1 and COM2. COM1 port is compatible to RS232 / RS422 / RS485 and CMOS signal levels. The Pin-outs of these ports are as shown below :
*Do not use pin no. 6 of PLC1/ COM1.
