2.4.3 Modbus Connections for Third Party Monitoring Systems
The PVI 50/60TL inverters can be connected to an external Data Acquisition System
(DAS) via an RS485 shielded twisted pair serial connection as shown in Figure 2.42.
These inverters can communicate with an external monitoring system via the
standard Modbus RTU protocol.
