Software Manual 167

Automation Tab

Current Range: With this option selected, the analog input will be configured to take current instrumentation input (0-40mA

or 4-20mA). The Input Range must also be configured.

Input Range: Select the range that will be connected to the input channel.

0-5 VDC and 0-10 VDC: This option will be available when the Voltage Range option is selected. In these modes, the value will

be scaled from the selected range (0-5 VDC and 0-10 VDC) to 0-32767 (decimal).

0-20 mA Positive Results Only and 4-20 mA Positive Results Only: These options will be available when the Current Range

option is selected In these modes, the value will be scaled from the selected range (0-20mA and 4-20mA) to 0-32767 (deci-

mal). No negative results will be displayed. If no signal is connected, the analog input value reported will be 0 (decimal).

4-20 mA Negative below 4mA: When this option is selected, the 4-20 mA range will be scaled from 0-32767 (decimal). A neg-

ative value will be displayed when nothing is connected to the input or the instrument is no longer supplying a current. This

setting can be used to detect a failed or disconnected instrument.

Note: Negative numbers are determined by using the most significant bit in the 16-bit decimal value as a signed bit. When

the most significant bit is 0, the value is positive. When the most significant bit is 1, the value is negative. Therefore, the value

read from the channel may be displayed differently depending on the device that is reading that value. For example, negative

values may also be read as any decimal value above 32767.

Analog Output

• Click on the Analog Output button and the following dialog window will appear:

Channel: A channel is a physical IO point that can be either analog or digital.

Modbus Address: This field indicate the register addresses for each channel. Configuration must be sequential.

Addresses are fixed sequentially from the base address.

Output Range: Select the type of signal to be supplied by the output channels.

Disabled: This option will completely disable the output channel.

0-5 VDC: When selected, the analog output will be configured to supply a DC voltage from 0-5 VDC. The output voltage will

be scaled to 0-32767 (decimal value in the IODB/Modbus Address field).

0-20 mA: When selected, the analog output will be configured to supply a current from 4-20 mA. The output voltage will be

scaled to 0-32767 (decimal value in the IODB/Modbus Address field).
