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
