Modbus
Many newer SCADA and Process Control systems utilize a direct
serial connection to measurement devices to provide an efficient
means to access process values. One of the many industry standard
protocols that use this serial connection is Modbus. There are
currently several versions of Modbus (ASCII, RTU, TCP/IP, and
others). Currently, ADS
® provides data using ASCII. Other versions
of Modbus may be available in the future. The ADS monitor serves
as a Modbus slave device and provides process values via Modbus
Holding Registers.
The following ADS FlowShark ® models support real-time operation
using Modbus ASCII to interface with third party equipment:
 FlowShark-AG*
 FlowShark-AG-M
 FlowShark-AL*
 FlowShark-AS*
 FlowShark-BG
 FlowShark-BL
 FlowShark-CG
 FlowShark-CG-1
