When the input condition to the Reset Set Flip-Flop function block is turned ON, that ON status is maintained (latched) in the function block and the ON output is maintained at the Output Enable signal. The ON status is maintained in the function block, so the Output Enable signal stays ON even if the input condition goes from ON to OFF. The signal maintained in the function block is turned OFF when the function block's RESET condition is turned ON. Fault Present Output Setting A Fault Present output can also be used in programming. To enable this output, select the Fault Present checkbox on the Out Point Tab Page of the function block properties dialog box. Error Handling and Error Resetting Error condition Input and Reset are active simultaneously. Behavior for error detection Output Enable Fault Present OFF ON (safety state) Resetting the error condition Make one of the signals inactive.

The Comparator function block compares the specified input signals (up to 8 inputs) with the comparison data set in the Configurator, and turns ON the Output Enable signal when all of the input signals match the comparison data. The Output Enable signal will be turned OFF when the input signals no longer match the comparison data. From 1 to 8 inputs can be set for the input signals. Set Parameters Parameter Comparison Data Setting range Default setting 00000000 to 11111111 00000001 (Input 1 is ON. ) (Individual bits correspond to Input 1 to Input 8) Optional Input Settings The number of inputs can be increased on the In/Out Setting Tab Page in the function block property dialog box.

" CD for Input n" indicates that the Comparator input signals are not the same as the comparison data. "×" indicates that the status is not applicable (the input signals and comparison data may or may not be the same). 152 Command Reference: Logic Functions Timing Chart Section 8-4 Output Enable 1 2 The horizontal broken lines in the above diagram represent the comparison data for each input. Output Enable turns ON when all of the input signals match the comparison data. Output Enable turns OFF when any of the input signals does not match the comparison data. 153 Command Reference: Function Blocks Section 8-5 8-5 8-5-1 Command Reference: Function Blocks Reset Diagram Reset Monitored Input Output Enable Default Maximum Number of Inputs General Description The Output Enable signal will turn ON if the Reset signal is correctly input while the input condition to the Reset function block is ON. This function block can be used to prevent the machine from automatically reset, e. g. , when the power to the NE1A-series Controller is turned ON, when the operating mode is changed (from IDLE Mode to RUN Mode), or when a signal from a safety input device turns ON. Conditions for Output Enable Turning ON · The Monitored Input and all enabled optional inputs must be ON. Conditions for Static Release Turning ON The Monitored Input and all enabled optional inputs must be ON. Conditions for Reset Required Indication Turning ON If the following condition is met, the Reset Required Indication will become a 1-Hz pulse output. · The Monitored Input and all enabled optional inputs must be ON. If the Reset Signal is set to Low-High-Low, the Reset Required Indication will turn ON when the next condition is met. [. . . ] With a single-cast connection, a Safety Master and Safety Slave communications 1:1. This connection can be set for either an input or an output, and separate connections are needed for each. In this manual, items used for general control purposes are called "standard" to differentiate them from devices, functions, data, and other items for which which safety measures have been applied. A CPU Unit used for standard control, such as CPU Units in OMRON's CS or CJ Series. [. . . ]
