    Functions Section 5-5-4 Using the Unit Memory Map Configuration Sheet To assist in the custom configuration of the Unit, a Configuration Worksheet has been provided in Appendix A. Values for all advanced functions can be entered in the worksheet. These values can then be easily transferred to data memory for use by the Unit.
  • Page 103 Functions Section Averaging and Alarms High and low limit alarms are processed before averaging is performed. It is thus possible that the averaged input data will still be within the set limits even when a high or low alarm has been given. This can happen when the upper or lower limit has been exceeded only momentarily, causing the High or Low Alarm Flag to turn ON even though the average value has not yet (and possibly never will) ex- ceeded the limits.

The range for input point 12 has been set to 0 to 20 mA. It has been determined that a 4 mA reading on the sensor indicates a pressure of 300 psi, and a 20 mA reading on the sensor indicates a pressure of 1200 psi.
  • Page 106 Functions Section 5-6-3 Averaging The averaging function can be used to perform averaging of many samples of data prior to reporting the value to the CPU Unit. This function is useful for reduc- ing or eliminating noise commonly found in analog input signals. When averag- ing is enabled for a particular input point, the Unit takes the requested number of input samples for that input point and computes an average before reporting data to the CPU Unit.
  • Page 107 Functions Section 5-6-5 Peak Hold The peak hold function can be used to detect peak conversion values of rapidly changing analog input signals.

    Functions Section Functions 9-4-1 BCD/Binary Mode The BCD/Binary Mode Bits (bits 8 to 15 of address 14) in RAM of the Analog Output Unit are used to select either BCD or binary mode for each output point. The default is BCD mode. The data format is specified for the following four values in RAM by using the BCD/Binary Mode Bit.
  • Page 187 Functions Section When the scaling lower limit is smaller than the scaling upper limit, the lower limit corresponds to output signal level 0%, the upper limit corresponds to output sig- nal level 100%, and positive scaling is performed. When the scaling lower limit is greater than the scaling upper limit, the lower limit corresponds to output signal level 100%, the upper limit corresponds to output signal level 0%, and reverse scaling is performed.

  • Page 189 Functions Section Output Signals When conversion data changes from the present value to a new value, the out- put signal is linearly changed to the new value within the output ramp set time instead of rapidly changing the output signal. Once the output signal reaches the new value, it remains unchanged until conversion data changes.

  • Page 199 User Programming Examples Section Programming In four-word operating mode, the same handshake bit in the allocated I/O words, Precautions in Four-word the PC Write Completed Bit, is used for both write and read operations in the Operating Mode Analog Output Unit. Therefore, even if exclusive control is performed for each read and write process, when a block in a program turns ON the PC Write Com- pleted Bit, other invalid blocks in the program may turn OFF the bit.

  • Page 200: Using Pulse Signals

    User Programming Examples Section Method 2 In this method, each work bit is turned ON when PC write process is completed, and the result is set in the PC Write Completed Bit according to an OR of these bits. This prevents the PC Write Completed Bit turned ON by one program block from being turned OFF by another program block.
