GWY-500 is a Protocol Converter / Data sharer for devices like PLCs, Inverters, Controllers etc. GWY-500 has a serial port, that connects to a serial device and a Profibus-DP-V0 port, that connects to Profibus network. Gateway allows serial devices to act as a slave on a Profibus network. It also allows Profibus Master PLCs to act as a serial device (e.g. Modbus Master or Modbus Salve).
Our Windows® based Gateway setup software makes it easy to configure the protocol converter. After choosing which protocol to be used for each port, you can program the Gateway to transfer the data blocks. Using a simple spreadsheet format, you can simply program the Gateway to fetch a specified number of registers or bits from one device and transfer them to the other. Powerful software allows you to have all the information transfers done continuously or allows the PLC to control which blocks of data are to be transferred.

Other Accessories required for the GWY-500 configuration and to use in actual application:
1. Gateway Configuration / Connecting Cable.
2. Gateway Setup Software .
3. Devices with communication cables.
Communication ports:
The GWY-500 has two communication ports. Pin-out of these ports are as shown
below:
*Do not use pin no. 6 of PLC1/COM1 port.
Data Line: The Profibus user group recommends the following colour coding for the data signal lines:
A-Data Line = Green B-Data Line = Red
These data signal lines must be connected to the corresponding signal terminals or pins at the master unit and other stations (i.e. A to A, B to B).
RTS: The signal RTS (TTL signal relative to Data Ground) is meant for the direction control of repeaters in case repeaters without self control capability are used.
