Blocking and Enabling of Messages with Process Information and Periodical
Information
The copy operation of messages with process information and periodical information can be
blocked and enabled:
• in the input-side process images
• in the output-side process images
This can take place with the following granularity:
• Per message
• All messages
• Per periodical information
• I/O Master Module
Changing the Execution Status of the Open-/Closed-Loop Control Function
• Halt and continue program
• Perform cold start or warm start of the program
Test Means
The available test means are:
(a) Halting of the execution due to a trigger condition (breakpoint)
(b) Execution of the task in cycle steps
The function (a) is not supported by SICAM WEB.
For the function (a) a trigger condition is defined in the tool "CAEx plus Online Test". A trigger
conditions consists of up to 4 conditions. The conditions of a trigger condition are combined
equal-ranking with AND or OR.
A condition compares a variable with a constant value to be specified:
Variable of the Type Condition <operator>
BOOL variable <operator> value = <>
INT or REAL variable <operator> value < = <> >
The function "halting the execution due to a trigger condition" halts the task, if the trigger con-
dition is satisfied. The trigger condition is evaluated at the end of the task.
Display Statistic Information
The following information on the application program is made available:
• Parameterized cycle time
• Current run time
• Maximum run time
• Number of time-outs that the system has registered
• Used memory space
• Compiler errors
During the course of the interrogation, the current run time and the number of time-outs can
be optionally reset (does not apply for SICAM WEB).
