The OPC Server for SCADA Modbus provides connectivity to Modbus compliant devices such as any PLCs, RTUs, DCSs, and other Modbus devices. This OPC Server has an Advanced Polling Engine that polls all devices and exclude the disconnected devices from the polling cycle. Once the disconnected device goes back online, it gets added back to the polling cycle. This will prevents any delays when any device goes down when having multiple devices into under one communication channels.
