8 FUNCTIONS

8.2 Safety Output Function

Number of safety output ON times integration function

This function counts the number of ON times of each output point within the range of 0 to 2147483647. The integration value

remains even though the output module is powered off. Whether to enable or disable the function can be set for each output

point from the module parameter setting window of the engineering tool or the program. When the value for "Number of ON

times integration function enable" is "1: Enable", the number of ON times at the corresponding output point is counted. When

"0: Disable" is set, the number of ON times at the corresponding output point is not counted.

Checking and clearing the number of ON times

The number of ON times can be checked and cleared with the program.

• When the ON time and the OFF time of the target output signal are less than 4ms, the output module cannot

recognize the output change and the number of ON times may not be counted.

• When the number of ON times integration value exceeds 2147483647, the count stops. To integrate the

number of ON times continuously, clear the integration value by using Number of ON times integration value

clear command Y (address: 1100H, 1200H).

Setting method

Set the number of ON times integration function in "Number of ON times integration function enable" from the "Parameter

Processing of Device Station" window of the engineering tool.

For the procedure to display the "Parameter Processing of Device Station" window, refer to the following.
