Accuracy
At ambient temperature of 55C: 3.5 to +0.5 min error per month
At ambient temperature of 25C: 1.5 to +1.5 min error per month
At ambient temperature of 0C: 3 to +1 min error per month
Retention time of built-in capacitor ---
*1 When the hardware revision for the Unit is A, the processing time is 1.1 ns (1.7 ns or less).
*2 When the hardware revision for the Unit is A, the value is 24 ns or more.
*3 Execution objects and variable tables (including variable names)
*4 Does not include Holding, DM, and EM Area memory for CJ-series Units.
*5 Does not include CIO and Work Area memory for CJ-series Units.
*6 Refer to the NJ/NX-series CPU Unit Motion Control User’s Manual (Cat. No. W507) for descriptions of axes.
*7 Data will be refreshed at the set interval, regardless of the number of nodes.
*8 “pps” means packets per second, i.e., the number of communications packets that can be sent or received in one second.
*9 As the EtherNet/IP port implements the IGMP client, unnecessary multi-cast packets can be filtered by using an Ethernet switch that supports IGMP Snoop-
ing.
