UM353-1B Function Blocks

3-21
L#A_=1 when Loop # alarm__ is active
L#N_=1 when Loop #
alarm__ is Not acknowledged
L#E_=1 when Loop #
alarm__ is enabled (when the alarm is disabled the E, N, and A bits are set to 0)
L#OS=1 indicates that all Loop # alarms are identified as Out of Service which means that all alarms function
normally but the OS flag indicates to a higher level device that they can be ignored. OS cannot be set locally.
3.2.11 AND_ - AND Logic
AND_ function blocks perform a logical AND on the three
inputs. Any unused input will be set high (1).
3.2.12 AOE_ - Analog Output- Ethernet
AOE_ function blocks are available and are assigned in
sequence with each use, station wide. Up to 32 AOE
blocks are available.
The range pointer parameter (Input R) enables the block
to pass the range scaling to AIE function blocks in other
Siemens 353 controllers connected over the Ethernet
network.
Each AOE block is automatically assigned Modbus
registers that can be accessed from any device having
Modbus/TCP Ethernet capability. See Table 3-6 in Section 3.2.7 AIE_-Analog Input - Ethernet for a listing of these
registers.
