♦
Setting a timer interval . The trace can be performed in increments of 5ms during a 5-2550ms cycle. To
sample data only once each cycle, set the interval to 0ms.
♦
Including the TRSM (170) instruction in the PLC’s program . This instruction identifies the points in
program execution where specified data is to be stored in Trace Memory. The timer interval must be set to
‘TRSM’.
Note: The buffer for Data Trace is 4K words.
CV-series PLC Sampling Range
The CV-series PLC can trace a maximum of 12 bits and 3 words and performs data tracing using one of the
following methods:
♦
Setting a timer interval . The trace can be performed in increments of 5ms during a 5-2550ms cycle.
♦
Including the TRSM(170) instruction in the PLC’s program . This instruction identifies the points in
program execution where specified data is to be stored in Trace Memory. The timer interval must be set to
‘TRSM’.
C-series PLC Sampling Range
The C-series PLC can trace a maximum of 12 bits and 3 words and performs data tracing using one of the
following methods:
♦
Setting a timer interval . A Data Trace can be performed at regular, independent intervals by setting a timer
interval from the peripheral device.
♦
Including the TRSM(45) instruction in the PLC’s program . This instruction identifies the points in
program execution where specified data is to be stored in Trace Memory.
Note:
Data Tracing cannot be performed from a Programming Console.
Setting Monitoring Conditions
The Data Trace or Time Chart Monitor must be activated before the settings can be configured. To select Data
Trace or Time Chart Monitoring mode, select the
Mode option from the Operation menu followed by either
Data Trace or Time Chart Monitor .
Note:
The mode of the Data Trace/Time Chart monitor component is identified prior to
activation from the invoking application.
The Time Chart Monitor/Data Trace Configuration dialogue allows the conditions for the Data Trace or Time
Chart Monitor to be set, i.e. specifying the data to be monitored, the intervals at which this is to occur and the
trigger conditions.
Use the following procedure to set conditions for the Data Trace or Time Chart Monitor modes.
1, 2, 3… 1. Select the Configure Trace/Time Chart button from the toolbar.
