Retention (non-volatiledata storage)2211SVC 440 795 M0100Retention (non-volatiledata storage)It is a requirement of system and machine controllers foroperating states or actual values to have retentive settings.What this means is that the values will be retained safelyeven after the supply voltage to a machine or system hasbeen switched off and are also retained until the next timethe actual value is overwritten.Permissible markers and function relaysIt is possible to retentively store (non-volatile memory) theactual values (status) of markers, timing relays and up/downcounters.The following markers and function relays can be set to haveretentive actual values:• Markers: M9 to M12, M13 to M16, N9 to N16• Up/down counters: C5 to C7, C8, C13 to C16• Text function relays: D1 to D8• Timing relays: T7, T8, T13 to T16h Factory setting:The retention function is not activated.h In order to ensure the full compatibility of CL-LSR/CL-LSTand CL-LMR/CL-LMT devices with the AC010 devices, thesettings for the retentive data were divided into the aboveareas.h Attention!The retentive data is kept every time the power supply isswitched off. Data security is assured for 1000000 writecycles.
