Sampling trace function

The sampling trace function collects the status of specified devices or register at every specified sampling timing. The collected data can be displayed on the programmer (T- PDS) screen in the format of timing chart (for devices) or trend graph (for register). The minimum sampling timing is the T1/T1S’s scan cycle.

This function is useful for program debugging and troubleshooting.

	T1	T1S
Sampling target	Devices (up to 8) or	Devices (up to 8) and
	Register (only 1)	Registers (up to 3)
Sampling capacity	256 times for device	256 times
	128 times for register

The collected data is stored in the T1/T1S internal buffer.

The buffer works as a ring buffer, and latest collected data can be displayed.

The sampling start/stop condition (arm condition) and the collection timing (trigger condition) can be specified by status changing of devices.

For detailed key operations for arm/trigger conditions setting on the T-PDS, refer to the manual for T-PDS.

NOTE

(1) On the T-PDS, select ‘3 registers + 8 devices’ as the sampling type.

(2) As the arm and trigger conditions, register values cannot be used.

(3) The After times setting is not effective for the T1/T1S.
