MOTOROLA MVME61006E-0163 Programming Timer
MVME61006E-0163 to improve the reliability of the PLC control system work, you can set up a timer specifically as a monitoring program part of the system to detect the operation status. If the program operation can end normally, the timer is immediately cleared; if the program operation failure, such as the emergence of a dead loop, etc., the timer can not be cleared at the set time to the time, when the PLC sends an alarm signal.
MVME61006E-0163 This method is used to realize the monitoring of the operation status of each part of the system when designing the application program. If the PLC to control an object, the preparation of the program can define a timer to monitor the running status of this object: the timer is set for the maximum time required to work on this object; when the object is started to run at the same time, also start the timer.
