Retentivity and backup
The 6ES7313-6CE01-0AB0: Backup time holds retentive data for 6 weeks after power loss. The retentive memory can be configured to protect inputs, outputs, memory bits, data blocks, timers, and counters. By default, no retentivity is preset, so assign the retentive range in HW Config before deployment. The isolation on the DP interface keeps ground loops out of the CPU, which matters when the controller sits in a panel alongside variable-frequency drives or switching supplies.
Sourcing
The 6ES7313-6CE01-0AB0 is a current-orderable CPU. Quoted to order; submit an RFQ for lead time and firm pricing. Because it is a compact unit with no expansion bus, verify that the integrated I/O and onboard DP satisfy your application before freezing the BOM line.
