EMUX
Direct Communication
On-site (or direct) communication with all monitors is available
through an IS PC communication direct connect cable (p/n 8000-
0054).
Modbus
Modbus is a protocol that allows for communication to occur
among multiple devices connected to the same network. It often is
used to connect a supervisory computer with a remote terminal unit
(RTU) in supervisory control and data acquisition (SCADA)
systems. IETG uses the Modbus protocol to enable a SCADA RTU
to interface with a FlowHawk directly through an EMUX (p/n
106226E) to obtain current data. The multiplexer in the EMUX
facilitates both serial communication between a flow monitor and
the RTU and wireless communication between a flow monitor and
the Profile or IntelliServe
®
software application.
IETG also uses Modbus protocol to allow a Telog
®
Ru-33 to
request data from a FlowHawk directly through a Triton – Telog
Comm Cable (p/n 8000-0054-01). Refer to Appendix E, System
