IM 151-7 CPU and S7-300

Se-

Action Result

1 In the SIMATIC Manager, navigate to the block

container of the S7-300 and insert an empty

organization block with the name OB 86 into the

block container.

This block ensures that the S7-300-CPU does not

switch to STOP if a station of the IM 151-7 CPU

fails/recovers.

Generate OB 82 in the same way.

2 Make sure that the mode selector of the S7 and IM

is set to STOP

Switch on the PS of the S7-300 and the PS of the

ET 200S.

The IM 151-7 CPU and S7-300-CPU

request a memory reset.

3 Reset the memory of the IM 151-7 CPU and

S7-300-CPU as follows:

 Press/rotate the mode selector to MRES. Hold

the mode selector at this position until the

STOP LED lights up for the second time and

then remains lit (approx. 3 seconds). Then

release the mode selector.

 You must press/rotate the mode selector back

to MRES within 3 seconds. The STOP LED

begins to flash rapidly and the CPU performs a

memory reset. You can now release the mode

selector. The CPU has completed the memory

reset when the STOP LED remains

permanently lit again.

Both CPUs have undergone a memory

reset.

4 In the PLC menu of the SIMATIC Manager, select

the Load command to transfer the program and the

hardware configuration to the S7-300-CPU.

Confirm all windows that appear with Yes.

The program and configuration are

downloaded from the PD to the CPU.
