To program each analog resting output voltage, enter a voltage from 0.0 to 5.0, into each box representing Analog Output 1, Analog Output 2, Analog Output 3, and Analog Output 4. Then press “Send Resting and Limits Æ Device”. This data is saved and remains resident within the respective RTU. This process is valid ONLY if the RTU is “Connected”.
The respective RTU is also equipped with the ability to turn on or off its output if a
Communications error occurs. This is true for the Master and Slave.
The output is an Open Drain output and should be used to sink not source current, 1Amp MAX. This typically means that the Output will supply a “Ground” to the device to turn it on or off.
The respective RTU also has the ability to control its respective Output during a communications failure. The output may be configured to an ACTIVE HIGH or ACTIVE LOW state during a communications failure. This can be useful as an alarm output or to turn a device on or off. A “Check” mark next to the “Discrete Output Comm Fail Enable” will force the output to an active HIGH or LOW, (depending on what is selected for an Active High or Active Low), during a communications failure. If you use the output to respond during a communications failure, you will not have control using the Modbus protocol. If you wish to use the output for something other than a comm. failure you will need to disable the “Discrete Output Comm Fail Enable”.
