Multi-dropping of Devices using Gateway
Gateway supports multidropping on both the ports. Following illustration explains multidropping of devices on
Gateway ports. Devices with protocols that support networking can be multi-dropped on RS485 port of
Gateway. Maximum 31 devices can be networked on Gateway RS485 ports.

Example 4.3:
Suppose Gateway is used to share data between multiple Modicon PLCs (Modbus Slave) to multiple
devices (Modbus Slave). Master - Master mode has to be used to enable data sharing. User must define
Blocks for sharing data.
Source PLC / Destination PLC: Setup Software appends ‘Com1’ and ‘Com2’ when protocols are same on
both the ports.
Source ID / Destination ID: These fields define the device ID on respective port side of Gateway. So using
ID’s it is possible to transfer data from device#1 on port1 to device#5 of port2.
