Dear Users,

Hope you everyone doing well.

Can anyone help me out below S5 STL instructions into S7 STL instructions as we are getting RS instruction in comments in simatic manager. If there is any other instruction for RS in s7 can anyone help me out.

SIMATIC S5                                                                         SIMATIC S7

C          DB 10;                                                                   OPN          DB 10

L           DL 2;                                                                      L                DBB 4

L            KF +115                                                                L                115

<>F                                                                                       <> I

JC         =M001                                                                  JC             M001

L             RS 120                                                                //L             RS 120

L             KM 00000000 001111000                               L 2#00000000 00111000

OW                                                                                       OW

T          RS 120                                                                   // T              RS 120

M001  BE                                                                            M001:           NOP 0

Waiting for response.

Thanks and kind regrads

Hello Muhammed,

The effect of this code is:

all markers are set to remanent
all timers are set to remanent
all counters are set to remanent

The last setting involves the priority of the alarm triggered organisation blocks.

OB2 .. OB5 are executed first, next OB6, next OB13 .. OB10

You don't need to program this in S7. This are settings in S7 hardware configuration

Kind regards,
BV

Dear Awais,

In S5 PLCs there is a System Data Area which contains System Data Words. These words are accessed with "RS" and can be used for different system behavior settings. Look for System Data Area section in your S5 CPU manual for more details.
