Installation, Operation & Maintenance Manual
OXYvisor Optical Oxygen Analyzer
To interrogate process variables such as oxygen, pressure, temperature, phase, amplitude, etc. refer to Table
3 for Base Addresses, then implement the offset, function code and choose data type as shown in the example
below. For basic Modbus RTU configuration settings, refer to Table 1.
The 4 relays in OXYvisor can be activated one at a time manually. Follow the steps below to specify, start and
stop individual relays. Until one relay is not deactivated, the other relay cannot be written to.
1.
Set the relay test number (Register Address : 44010). The values can be set to 1 , 2 , 3 or 4 for the
corresponding relay.
2.
Set the relay test position (Register Address : 44011). The value can be set to 0 to OPEN and 1 to
CLOSE the relay. (Note: The relay will not open or close unit you activate it in the next step.)
3.
Activate the relay status (Register Address : 44012). To activate, set the relay status value to (0X01).
4. To deactivate the relay set the relay status (Register Address : 44012) to (0x02).

Note: The “minus offset” should be 40000 for all the above read/write only registers.
*Addresses which are 4bytes long, needs 2 registers updated at once and function code 16 must be used.
