8.1 Product Specifications
The ProTalk Modbus Master/Slave Communication Module allows Schneider
Electric Quantum processors to interface easily with other Modbus protocol
compatible devices and hosts. The data transfer from the Quantum processor is
asynchronous from the actions on the Modbus network.
Compatible devices include not only Modicon PLCs (which all support the
Modbus protocol) but also a wide assortment of end devices.
8.1.1 Features and Benefits
Many host SCADA applications support the Modbus protocol, while devices
commonly supporting the protocol include several PLCs, as well as many other
third party devices in the marketplace. (For a partial list of devices that speak
Modbus, please visit the ProSoft Tested section of the ProSoft Technology web
site).
