Changing IM 151-7 CPU (6ES7 151-7Ax00..) to IM 151-7 CPU (6ES7 151-7AA10-0AB0)

11-2

ET 200S IM 151-7 CPU Interface Module

A5E00058783-04

 SFC 13 ”DPNRM_DG”

This SFC always runs “quasi-synchronously” when called in OB 82.

It always runs asynchronously on the IM 151-7 CPU (6ES7 151-7AA10-0AB0).

Note

In the user program, all that should take place is that the task should be called in

the OB 82. The evaluation of the data, which should take into account the BUSY

bits and the acknowledgement in the RET_VAL, should take place in the cyclic

program.

Tip:

We recommend using the SFB 54 instead of the SFC 13 with the IM 151-7 CPU

(6ES7 151-7AA10-0AB0).

SFC 20 ”BLKMOV”

Previously this SFC could also be used to copy data from a non-process-related

DB.

The SFC 20 no longer has this functionality. The SFC 83 ”READ_DBL” must now

be used for this purpose.

SFC 54 ”RD_DPARM”

This SFC is no longer available. The asynchronous SFC 102 ”RD_DPARA” must

be used instead.

SFCs which may give different results

If you only use logical addressing in your user program, you can ignore the

following points.

If you use address conversions in the user program (SFC 5 ”GADR_LGC”, SFC 49

”LGC_GADR”), you must check the slot assignment and logical start address

assignment for DP slaves.

 The diagnostic address of the DP slave is now always assigned to slot 0

(station proxy).

 The DP slave is integrated in STEP 7:

The interface module (slot 2) may have its own address

(e.g. IM 151-7 CPU as I slave).
