4.0 Installation

4.2 Modbus Communication Connection

The SF-1020i flowbench uses a programmable

logic controller (PLC) connection to control

the internal components of the flowbench. The

flowbench utilizes a Modbus TCP/IP network via

the internal controller. This option allows customers

to connect the flowbench controller to their Modbus

TCP/IP network and facilitates flowbench control

and the exchange of data. Once the flowbench has

been properly connected to your system via an

RJ-45 cable (Figure 4.2) and configured (refer to

configuration data in chart below) use the following

commands to communicate, control and read data

from the flowbench.
