4.5.3.1.1.1 Function
The Function parameter allows the communication ports to be set as Modbus® Master, Modbus® Slave,
Wireless Monitor, Redundant Port, or Disabled.
4.5.3.1.1.1.1 Modbus® Master
Master mode allows the communication port to poll any device using the Modbus® RTU protocol. This
setting is also utilized for Wireless Modbus® Master.
4.5.3.1.1.1.2 Modbus® Slave
Slave mode allows the communication port to be polled by any Modbus® Master device using the
Modbus® RTU protocol. This setting is also utilized for Wireless Modbus® Slave.
4.5.3.1.1.1.3 Wireless Monitor
This mode is exclusively for wireless communication to our SenSmart 7000 Series wireless gas detectors.
4.5.3.1.1.1.4 Redundant Port
This setting allows the user to create a redundant port which uses the settings from another port that is
already configured. Redundant mode works with ports configured as Modbus®
Master. When configured
as a redundant port, the Primary port communicates until it gets a communication error. The ViewSmart
1600+ then switches to the redundant port and continues to poll the slave nodes. When communication
has switched to the redundant port the ViewSmart 1600+ trips the Fault relay, beeps, and displays a
warning telling the user there has been a communication error. The user is able to ignore the warning for
12 hours or Test the Primary port. Ignoring the problem gives technicians time to trouble shoot and fix
the problem. If the problem is not going to be fixed, the warning message can be cleared permanently by
disabling the redundant port. If the user chooses to test the port and it passes, a success message will
appear and the error message will be cleared.
Before a Primary port switches to its redundant port, a scan must fail 3 times. All channels setup to use
the primary port are polled. At the end of the scan, if an error has occurred on any channel, the error
