Software Conversions Instructions Chapter 3

On Delay Timer

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

RSLogix 5000 software for Statement List and Ladder formats.

In S5 the time base is determined by the digit after the decimal point in the statement L KT xxx.y, where xxx denotes the

preset of the timer and y denotes the time base as one of the following:

.0 => 0.01sec

.1 => 0.1sec

.2 => 1sec

.3 => 10sec

In RSLogix 5000 software, the time base is in milliseconds.

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_bit2

Output Q4.0 out_bit1

=Q4.0

T2.Pre := 9000;

T2.Reset := data_bit2;

T2.TimerEnable := data_bit1;

out_bit1 := T2.DN;

where timer T2 is defined as data type FBD_TIMER in the

program tags as follows.

1 2 ... 54 55 56 57 58 59 60 61 62 63 64 ... 139 140
