Simatic/TI 505 Ethernet Driver Help

P 15/16, 0/1 Not used, set to 0

*Elements A and B are write-only triggers. Writing 1 to the triggers sets the mode. The mode (or status) is

reported in Element L (Bit 12).

**If a word is selected for the analog alarm V-flags, element L is written as bit 12 is written. If a C or Y is

selected, bit 12 (element L) is not used.

Note: If an analog alarm is programmed and not disabled, the controller will begin to monitor the programmed

variables as soon as the controller is placed in RUN mode.

ACF Bit Definitions

Analog Alarm Control Flag Data Element Format

The server default settings are shown in bold.

MSB LSB

ABCD EFGH IJKL MNOP QRST UVWX YZab cdef

The ACF 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.
