The Modbus Driver module allows the Ignition OPC UA server to communicate with any device that supports the Modbus protocol, that is, the Modbus TCP and Modbus RTU over TCP protocols.
The Modbus Driver module can connect directly to devices that support Ethernet communications or it can also connect to Modbus devices through a Gateway device.
See the following sections for detailed step-by-step instructions:
The Siemens Drivers module provides support for connecting to the following PLCs via TCP/IP using the S7 protocol:
For step-by-step instructions on how to connect to Siemens Drivers, see Siemens.
UDP and TCP
The UDP driver is a strictly passive listener. The UDP driver is configured to listen to one or more ports on a given IP address.
The TCP driver is configured to connect to one or more ports on a given IP address. This driver can listen, as well as write back to the connected port.
Rules are configured that dictate how the incoming data is interpreted.
For step-by-step instructions on how to connect to TCP Drivers, see UDP and TCP Driver.
The DNP3 module allows the Ignition OPC UA server to communicate with other devices that support the DNP3 protocol (DNP3 outstations).
See the following sections for detailed step-by-step instructions, see DNP3
The BACnet driver allows an Ignition OPC UA server to communicate via the BACnet protocol.
More information can be found on the BACnet page.
