6.1.2 Watchdog behaviour
1490
For all ecomatmobile controllers the program runtime is monitored by a watchdog. If the maximum
watchdog time is exceeded, the controller carries out a reset and starts again (SafetyController:
controller remains in the reset; LED goes out).
Depending on the hardware the individual controllers have a different time behaviour:
Controller Watchdog [ms]
BasicController: CR040n 100
BasicDisplay: CR0451 100
CabinetController: CR030n 100...200
ClassicController: CR0020, CR0032, CR0505 100
ExtendedController: CR0200, CR0232 100
PCB controller: CS0015 100...200
SafetyController: CR7nnn 100
SmartController: CR25nn 100...200
PDM360: CR1050, CR1051, CR1060 no watchdog
PDM360compact: CR1052, CR1053, CR1055, CR1056 no watchdog
PDM360NG: CR108n no watchdog
PDM360smart: CR1070, CR1071 100...200
