6000 & RAM 9000 Software Manual
Disabled:
This option will completely disable the channel so the channel will always report a zero. The
Input Range is configuration will be disabled as well.
Voltage Range:
When this option is selected, the analog input will be configured to take a DC voltage
range. The Input Range must also be configured.
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 (decimal). 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 negative 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 appears if analog output is supported for the
model in use:
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.
