PLC States 4.6 PLC States 4.6.1 RUN 4.6.2 STOP 4.6.3 Online Reset Events and commands cause the PLC to adopt different states. � The user program is running. � The PROFIBUS state is either "Operate" or it remains "Offline". Data is transferred via the external process image which is not synchronised with the user program cycle. � The user program stops running between two cycles. � PROFIBUS retains its state, i.e. "Operate". � The user program no longer runs. � The state of PROFIBUS changes to "Clear". Zeros are sent to the DP slave outputs. The reaction of the remote data depends on the peripheral (DP slave). � Except for the Retain variables (VAR RETAIN), all variables are reset to the value that they were originally initialised to (also applies to the variables declared as VAR PERSISTENT!!). Variables not explicitly assigned an initialisation value are set to their default initial values (e.g. integers are set to 0). Prior to overwriting the variables, CoDeSys displays a security prompt. A Reset is the same switching off the controller and turning it back on (warm boot) while the program is running. 112 E 700 GB
4.6.4 Online Reset (cold) 4.6.5 Reset (original) � The user program no longer runs. � All variables are reset. PLC States This command is very similar to the Reset command, except that all variables - including the Retain variables - are reset to their initialisation values. Online Reset (cold) is the same as launching a program when it has first been loaded into the controller (cold boot). � The user program is cleared. The controller is returned to its original unmodified state. � All variables, including the remanent ones (VAR RETAIN and VAR PERSISTENT) are reset to their initialisation values. The CoDeSys runtime system does not support the "PERSISTENT" property of variables. 113
