4 Functions
4.2.5 Test function
This function is to output pseudo-fixed value to a buffer memory for debugging sequence program.
The value can be output to the buffer memory without input of voltage and current.
(1) How to use the test function
1) Using the intelligent function module switch setting, you can start the test mode to output the
fixed value.
2) For procedure for the intelligent function module switch setting.
For GX Works2, refer to 7.6.2.
For GX Developer, refer to 7.7.2.
3) To finish the test mode, the set value is returned by the intelligent function module switch
setting, and after that, it enters to a measuring mode by resetting it.
(It resumes with the previous set value, electric energy and periodic electric energy.)
(2) Content of fixed-output
For the value to be output to the buffer memory, refer to Table 6.1-1 to 6.1-3 in 6.1 Buffer
memory assignment.
(3) LED display when using the test function
All LED lights.
(4) I/O signals when using the test function
Unit READY (Xn0) only ON. Other input and output signals are all OFF.
(5) Precautions for using the test function
Because fixed-output is output to the buffer memory, isolate the actual device to avoid
unexpected operation before running the sequence program.
