137 = **6 Example** =
138
139 The input analog of all channels（-10V~~10V）is stored inside the data memory（D8112, D8113）in the form of data. Values will be automatically stored when the “END” order is sent out. The value is calculated by the designated analog data conversion characteristics of the special auxiliary relays M8112 and M8113.
140
141 == Basic Program Examples ==
142
143 **✎Note: **
144
145 1. Start M8112 and M8113; designate the analog data conversion characteristics of CH1 and CH2.
146 1. After execution of analog data conversion, do not change the values of D8112 or D8113 through operator program, programming tools or graphic operating terminal.
147
148 The following program can set CH1 and CH2 into voltage input mode. After ADV conversion, values of all channels are stored into D0 and D2.

152
153 == Examples of Applications ==
154
155 Since the LX3V-2ADV-BD does not have offset and gain functions, if it needs for the values out of the standard specifications, Additional programming orders will be needed to multiply or divide the converted value.
156
157 **✎Note: **
158
159 1. Since the use of additional programming orders, the converted precision and resolution of the analog value are different with the specifications.
160 1. The original range of the analog output does not change.
161
162 **Voltage Input Mode**
163
164 Under the voltage input mode, the 2ADV will convert the analog value -10V~~10V into data output -2000~~2000. If the data range used in the application is 0-20000, then the range -2000~~2000 must be converted into 0-20000, as is shown in the following program examples. The data converted from the analog values are stored in D8112 or D8113.
165
166 Since the data range is converted from -2000~~2000 into 0-20000，therefore the resolution of the analog input is no longer just 8uA.
167

169 [[image:LX3V-2ADV-BD_html_e5767d5bf37b750e.png||height="200" width="700" class="img-thumbnail"]]
170
171 If the data range used in D0 is (0-20000), please refer to the following text：Figures used in the user’s applications：D0=5×(D8112 or D8113)+10000.
172
173 We can give an example as follows based on the program of the above mentioned formula (under the situation of CH1)
