AS300 Series Module Manual _2 2-8 CR# Name Description Defaults 12: 100 ms 22 Channel Alarm Setup 0: open channel alarm 1: close channel alarm bit0: channel 1 bit1: channel 2 bit2: channel 3 bit3: channel 4 0: warning 1: alarm bit8: error in the power supply bit9: error in the module hardware bit10: error in calibration 0 23 The minimum scale range for channel 1 For analog-digital modules, it is much more convenient if the system can convert digital values to floating-point values for earier understanding. Here you can set the minimum and maximum scale ranges of corresponding floating-point values for channels.
For example, if the scale range for an analog to digital input channel is ±10.0 V, it indicates the maximum value is +10.0 V and the minimum value is -10.0 V. If the scale range for an analog to digital input channel is 4 mA ~ 20 mA. It indicates the maximum value is 20 mA and the minimum value is 4 mA. When the format is set to integer in HWCONFIG, the scale range is invalid. You can also use PLC instruction DSCLP (API0217) and set SM685 to ON to use floating-point operations.
