LRSF Bit Definitions

Ramp / Soak Status Data Element Format

The server default settings are shown in bold.

MSB LSB

ABCD EFGH IJKL MNOP

The LRSF bit has the following format:

V/W, X/Y

V=0-based bit addressing. Bit 0 is MSB.

W=1-based bit addressing. Bit 1 is MSB (Simatic 505 documentation).

X=0-based bit addressing. Bit 0 is LSB.

Y=1-based bit addressing. Bit 1 is LSB.

Element LRSF

bit

Description

A 0/1,

15/16

1=Restart at the first step. To restart, toggle bit off, on, then off again. The restart

occurs on the trailing edge of a square wave.

B 1/2,

14/15

1=Hold at the current step. To hold, set bit on.

C 2/3,

13/14

1=Jog to next step. To jog, set bit on. Jog occurs on the rising edge of a square wave.

D 3/4, 1=Finish. Indicates ramp/soak is completed.
