207 -
208 -② Configure the currently connected PLC (take the LX5V-2416 model as an example) and BD board model on the BD board configuration interface: Select “LX5V-2PTWDAI" in the device bar on the right side of the BD board configuration interface and double-click to add it to the corresponding slot position of PLC (slot number 1 or 2, the software will select slot 1 by default, and right-click to move down to slot 2);
209 -
210 -③ After adding the BD board to the slot, double-click or right-click to select configuration parameters to enter LX5V-2PT2DAI-BD configuration parameters interface, as shown in the following figure. Configure related parameters on this interface.

220 -

222 -
223 -[[image:image-20221222112424-2.png]]

228 -
229 -**The parameter configuration interface is as follows:**
230 -
231 -~1. Module setting: Set response time (The response time is the interval time between PLC acquisition of BD board data. Range: 0.1ms to 3276.7ms).

235 -2. PT configuration:

237 -[[image:image-20221222112628-5.png]]
238 -
239 -* Check enable channel to set whether to enable the current BD board channel.
240 -* Sensor type: PT100 by default.
241 -* Setting the filtering intensity can reduce the jitter of BD channel value. The default configuration of filter intensity is 4. Level 0 is the lowest and level 9 is the highest. The filter intensity can be adjusted according to actual use.
242 -* Check enable overrun detection to judge that when the upper and lower limits of temperature exceed the current setting temperature, the host computer will prompt an error.
243 -* Check enable calibration, you could calculate the gain offset according to the following formula to convert the corresponding channel value:
244 -
245 - Channel value = actual temperature value × gain value + offset value
246 -
247 -When the channel value deviates from the actual temperature value, the channel can be calibrated by setting the gain offset, for example:
248 -
249 -* The input temperature of control channel is 0℃, the value of acquisition channel is 30 (unit: 0.1℃), and the actual channel value should be 0 (unit: 0.1℃).
250 -* The input temperature of control channel is 500℃, the value of acquisition channel is 5200 (unit: 0.1℃), and the actual channel value should be 5000 (unit: 0.1℃).
251 -
252 -Suppose the gain is a, and the offset is b, then[[image:image-20221222112833-6.png]]
253 -
254 -Solve and get[[image:image-20221222112858-7.png]] The calibration can be completed by setting the corresponding gain offset to the current channel.
255 -
256 -**✎Note**: **Using gain and offset calibration can only reduce the linear error. Since the PT100 resistance and temperature curve are nonlinear, there is still a certain error in partial temperature after the calibration is successful.**

258 -3. DAI configuration:
259 -
260 -[[image:image-20221222112945-8.png]]
261 -
262 -
263 -* Check enable channel to set whether to enable the current BD board channel.
264 -* The conversion mode is set to DAI conversion mode by default, and the measurement range is 4mA~~20mA (0~~2000).
265 -* Output state after stop: When PLC stops, the output state of BD board channel mainly includes the following three types:
266 -
267 -Output clear: When PLC stops, the output current of BD board channel is 4mA
268 -
269 -Output hold: When PLC stops, the channel output of the BD board maintains the digital current value set by the corresponding channel in the current I/O mapping device.
270 -
271 -Output preset value: When PLC stops, BD board channel outputs preset digital value or preset analog quantity corresponding to the current value.
272 -
273 -* Check enable calibration, you could calculate the gain offset according to the following formula to convert the corresponding channel value:
274 -
275 -Channel input digital value = actual output current corresponds to digital value × gain value + offset value
276 -
277 -* When the channel value deviates, you could also set the gain offset to calibrate the channel. For example:
278 -
279 -* When the channel input digital value is 0, the multimeter measures the output current of BD board channel to be 5mA (corresponding digital value is 125).
280 -* When the channel input digital value is 2000, the multimeter measures the output current of BD board channel to be 5mA (corresponding digital value is 1875).
281 -
282 -Suppose the gain is a, and the offset is b, then[[image:image-20221222113055-9.png]]
283 -
284 -Solve and get[[image:image-20221222113102-10.png]]The calibration can be completed by setting the corresponding gain offset to the current channel.
285 -
286 -4. Set I/O mapping. The channels are mapped to R device according to the current number of BD board channels by default. As shown in the following figure, BD board CH1 to CH4 is mapped to device R0 to R3.
