Property
System power supply (PS)
Load current supply PM
As of FW version V3.0 of the R-CPUs, the firmware between CPU and display is no longer separated. The firmware of the
1)
display is included in the firmware of the R-CPU.
If you use PROFINET devices that do not support H-Sync forwarding in S7-1500R, additional cycle time increases may
2)
occur in the RUN-Redundant system state. If the cyclic program exceeds the cycle monitoring time, the time error OB
(OB 80) may be started. You can find more information in the Events and OBs section.
Special case: Operating R/H CPU individually
You can operate an R/H CPU as a single CPU. If you do, please note the following:
• You always configure 2 R-CPUs or H-CPUs for S7-1500R/H, even if you only set up one CPU.
• The MAINT LED on the CPU is always yellow (maintenance demanded):
– The R/H system is not in redundant mode.
– No partner CPU was found.
