CPU 1515R-2 PN (6ES7515-2RM00-0AB0)

Equipment Manual, 11/2019, A5E42009914-AB

Description

There are two duplicate CPUs that synchronize their

data via redundancy connections within a PROFINET

ring. If one of the CPUs fails, the other CPU retains

control of the process.

The system automatically generates the messages

for the system diagnostics and outputs these mes-

sages via a programming device/PC, HMI device or

the integrated display. System diagnostics infor-

mation is also available when the CPUs are in oper-

ating state STOP.

Trace functionality supports you in troubleshooting

and/or optimizing the user program.

You record device tags and evaluate the recordings

with the trace and logic analyzer function. Tags are,

for example, drive parameters or system and user

tags of a CPU.

Trace and logic analyzer functions are suitable for

monitoring highly dynamic processes.

Note: Note that the S7-1500R/H redundant system

supports recording of measurements. However,

saving the measurements to the SIMATIC memory

card is not supported.

All IO devices are connected redundantly in the re-

dundant S7 1500R/H system. All IO devices as-

signed to the system must therefore support system

redundancy S2.

If the role of the CPUs changes, the new primary

CPU takes over the PROFINET IO communication.

The switched S1 device function of the CPU enables

operation of standard IO devices in the S7-1500R/H

redundant system.
