Trial Operation and Debugging
Section 10-2
Note
Use the CX-Programmer to turn ON the Sampling Start Bit (A508.15). Never
turn ON this bit from the user program.
The following traces can be executed.
Scheduled Data Trace
A scheduled data trace will sample data at fixed intervals. Specified sampling
interval is 10 to 2,550 ms in 10-ms units. Do not use the TRSM(045) instruc-
tion in the user program and be sure to set the sampling period higher than 0.
One-cycle Data Trace
A one-cycle data trace will sample I/O refresh data after the end of all cyclic
tasks. Do not use the TRSM(045) instruction in the user program and be sure
to set the sampling period higher than 0.
Data Trace via TRSM(045)
A sample will be taken once each time the TRACE MEMORY SAMPLING
instruction (TRSM(045)) instruction is executed. When more than one
TRSM(045) instruction is used in the program, a sample will be taken each
time TRSM(045) is executed after the trace trigger condition has been met
until trace memory is full.
Data Trace Procedure
Use the following procedure to execute tracing.
1,2,3...
1.
Use the CX-Programmer to set trace parameters (select
PLC - Data Trace
and then select
Operation - Configure
):
Addresses of the sampled words/bits, sampling period, delay time, and
trigger conditions.
2.
Use the CX-Programmer to start sampling or turn ON the Sampling Start
Bit (A508.15).
3.
Put the trace trigger condition into effect.
4.
End tracing.
5.
Use CX-Programmer to read the trace data.
a) Select
Data Trace
from the PLC Menu.
b) Select
Select
from the Operation Menu.
c)
Select
Execute
from the Operation Menu.
d) Select
Read
from the Operation Menu.
