3 Communication Overview
Extensive communication options enable the ControlMaster to be integrated into larger control systems easily or connected to
other process instrumentation.
3.1 Communication Options
3.1.1 Ethernet
Optional Ethernet communications enable the ControlMaster to be integrated in to an Ethernet network quickly.
The following functionality is provided:
Email
Notification of a critical process event or status can be made by email. Multiple events can trigger an email that can be
sent to multiple recipients.
Webserver
ControlMaster's integrated webserver enables the current status of the process and controller to be viewed remotely
using a standard web browser.
MODBUS TCP
Process values and status can be communicated to and from the ControlMaster in real-time using MODBUS TCP,
enabling it to be integrated easily into larger control systems or connected to a data recorder.

3.1.2 RS 485 MODBUS
Using RS 485 MODBUS, values and status can be communicated to and from the controller in real-time via an RS 485
connection.

4 Communication Level
4.1 Communication
The Communication parameters are accessed from the Advanced access level – refer to the User Guide supplied with your
instrument for access details.
Note. Communication parameters are displayed for the type of communication board fitted in the instrument, for example,
if a MODBUS board is fitted, MODBUS parameters are enabled, but Ethernet parameters are not enabled or displayed.
Used to setup communications parameters for the MODBUS / Ethernet / email communication
protocols.
MODBUS Refer to Section 5, page 13 for details of MODBUS coils and registers.
Device Address The unique network address assigned to this device (1 to 247) that allows the host system to
identify the instrument on a MODBUS link.
Reverse IEEE Data All analog data is read from the instrument in IEEE (Institute of Electronics and Electrical Engineers)
format contained in adjacent registers representing the data in high word / low word order.
Select Yes to reverse the IEEE data order, otherwise select No.
