238 -
239 -* Check enable channel to set whether to enable the current BD module 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℃).

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.**

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 module 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 module 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 module 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 module 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 module channel to be 5mA (corresponding digital value is 1875).
