REVISION 4
On COM1 side it supports serial protocols (e.g. Modbus Mastre, Modbus Slave) and on COM2 side it has Profibus DPV0
Slave Protocol.
Profibus Slave uses internal memory. It is divided into two parts, Input Area and Outptut Area. Profibus master writes data in
Output Area and reads the data from Input Area. With Gateway project it is possible for serial devices to read the data from
Output Area and write the data in Input Area of Profibus Slave.
GWY-500 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. It has two communication ports, one with Profibus-DPV0 network
interface (9.6Kbps to 12 Mbps) and serial port with RS232 / RS422 / 2 or 4 wire RS485 (300 to 115.2K).
Microsoft Windows® based configuration software, Gateway Setup, helps 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, condition for block execution etc.
Block may contain information like copy number of words 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 Profibus-DP Slave devices and serial devices (e.g. PLC or SCADA).
3.3 GWY-500 Configuration
GWY-500 can communicate with serial and Profibus devices using appropriate cables and configuration. Microsoft
Windows® based configuration software, Gateway Setup, configures the GWY-500 unit.
‘Configuration’ means making the GWY-500 unit work as per system requirements.
Complete configuration for a GWY-500 using the Gateway Setup is termed as a ‘Project’. A Project consists of Devices to
be attached on two ports, Communication settings for two ports to communicate with two devices, Register addresses for
data transfer, Conditions for data transfer etc.
GWY-500 can now communicate with the specified devices without any change in the GWY-500 hardware. To
communicate with a device, GWY-500 needs Communication Drivers for the devices and ‘Gateway - Device’
communication cables.
Each Device has a unique and predefined protocol for communication. GWY-500 driver has this protocol to communicate
with the desired device. As two devices are connected on GWY-500, it requires two drivers for communication
3.4 Configuration of GWY-500 (IBM Download)
User MUST download Project, PLC1 driver and PLC2 driver in Gateway before installing any system using
Gateway. Gateway can accept drivers and configuration data on either of the ports. User needs a special IBM download
cable for downloading configuration in Gateway. All configurations can be downloaded only form Serial port (Port 1). The
other port is dedicated for Profibus Slave (Port 2).
If any change in the current / working project is made, user must download the changed project in Gateway.
