switch or the remote latch clear operation. When performing the sampling trace
after latch clear, select [Start trace] or [Registry trace] before executing the sampling
trace again.
(a) Areas where sampling trace can be executed
The sampling trace can be executed from other station on the network or serial
communication module. However, the trace cannot be executed from multiple
areas at once. The trace can only be executed from one area with CPU module.
(b) How to hold and clear [Trace setting]
The trace setting (sampling trace file) registered in the CPU module is latched.
Even if turning power supply ON (OFF ON)/resetting the CPU module, the
sampling trace can be executed again in the trace setting at the time of
registration. However, the previous trace result cannot be read.
Also, when the trigger condition of the sampling trace is established, the latched
[Trace setting] will be cleared since it is not recognized as the trigger condition.
(SM800 (trace ready) is turned OFF.)
Register [Trace setting] again by GX Developer.
1) When "standard RAM" is selected in target memory
• The power supply was turned on (off to on), CPU module was reset, or
CPU module status was changed from STOP to RUN after setting to
change the size of local device in the standard RAM
parameter to CPU module.
• On the status of sampling trace file corruption, the power supply was
turned on (off to on), or CPU module was reset.
*1 : Creating a new local device is included.
