Sample Low And High Alarm Setpoints - Siemens SIMATIC 505 Installation And Operation Manual

Internal Register Structures (continued)
3-12 Advanced Function Programming
The following steps explain how data is loaded into the SIMATIC 505–2556
module.
1. V- or K-memory tables are constructed with the scaling, alarm
setpoints, filtering and averaging units. In the example below, low
alarm and high alarm setpoints are loaded for each channel from V1
through V32. V1 – V16 contain the low alarm setpoints for channels
1–16, and V17 – V32 contain the high alarm setpoints for channels
1–16. See Figure 3-7.

2. By monitoring the state of the Module_Ready flag, data is moved to
the WY output registers. See Figure 3-8.
