The following conventions are used to indicate and classify precautions in this manual. Always heed the information provided with them. Failure to heed precautions can result in injury to people or damage to property. !DANGER !WARNING Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.

The NEG instruction can be used to obtain two's complements from absolute values. 315 Analog Output Slave Units Note Section 6-5 Pulses may be output if the power supply to the Analog Output Unit is turned ON and OFF excessively. When controlling an output device like an inverter, be sure the output device is OFF before turning the power supply to the Analog Output Unit ON or OFF. 6-5-2 I/O Data Types and Allocation Methods The Analog Output Unit has only one type of output data. The output data is allocated by default, so there is no need to change the setting. Two words (4 bytes) of output data is allocated. The data is output as two's complements. 15 8 7 0 Analog output value for Output 0 Analog output value for Output 1 I/O Data Allocated in the Master Unit 316 SECTION 7 Temperature Input Units This section describes the Temperature Input Units. 7-1-1 7-1-2 7-1-3 7-2 7-2-1 7-2-2 7-3 7-4 7-5 Temperature Input Units .

They can internally perform math operations on temperature input values, which previously required ladder programming at a host PLC. Temperature data can be obtained from math operations and allocated as I/O in combination with Temperature Status Flags or other status information. The CX-Integrator can be used to easily allocate and monitor status information, set Temperature Input Unit functions, and monitor data. 7-1-2 List of Data Processing Functions The following tables list the data processing functions that can be used with Temperature Input Units. Refer to 11-5 Temperature Input Unit Functions for details on functions and setting methods. Function Details Calculates the average of the past eight temperature input values, and produces a stable input value even when the input value is unsteady. Scaling allows conversion of temperature input values into values using the industry unit required by the user. It reduces the number of operations requiring ladder programming in the master PLC Unit. Scaling also supports an offset function for compensating for mounting errors in sensors and other devices. Holds the maximum and minimum temperature input values. Holds the top and valley temperature input values. Default Moving average disabled. Moving average Scaling Disabled 0 to 28, 000 Peak/bottom hold Top/valley hold Rate of change Comparator Disabled Disabled Calculates the rate of change for temperature input valDisabled ues for each sampling period. Compares the temperature input value or data after math Disabled processing (value for peak, bottom, top, valley, rate of change) with the four set values HH, H, L, and LL, and indicates the result with the Temperature Status Flags. Can be used to disable detection of input errors (including Disabled disconnection).

Appendix D Note The communications current consumption indicated for Expansion Units is the additional current consumed when the Expansion Unit is connected to a Basic Unit. For example, the current consumption for a combination of a CRT1-ID16 Basic Unit and an XWT-OD16 Expansion Unit is 80 + 10 = 90 mA.
