Software Conversions Instructions Chapter 3

Off Delay Timer

The following example shows how an OFF DELAY function in SIMATIC S5 can be converted into a similar function in

RSLogix 5000 for Statement List and Ladder formats.

The RSLogix 5000-equivalent bit/word for each bit/word used in the S5 in the following example is shown below.

Usage of the RES instruction is optional.

Function S5 RSLogix 5000

Timer Enable I1.0 data_bit1

Reset I1.1 data_bit1

Output Q4.0 out_bit1

S5 Statement List RSLogix 5000 Structured Text

AN I1.0

L KT9.2

SF T3

AI1.1

RT3

AT3

=Q4.0

T1.Pre := 9000;

T1.Reset := data_bit2;

T1.TimerEnable := data_bit1;

TOFR(T1);

out_bit1 := T1.DN;

where timer T1 is defined as data type FBD_TIMER in the

program tags as follows.

1 2 ... 56 57 58 59 60 61 62 63 64 65 66 ... 139 140
