Time Stamping Of The Input Signals With Im 650; Principles - Siemens SIMATIC ET 200PA SMART Operating Instructions Manual

● The total amount of input data must not exceed the following values:
– 128 bytes per slot
– 244 bytes per ET 200PA SMART
These limits are checked during configuration.
● "Standard" input data and additional input data are internally consistent but not consistent
relative to each other.
The following figure illustrates this point.
The additional input data is updated at longer time intervals than the "standard" input data.

Time stamping of the input signals with IM 650

7.4.1

Principles

Time stamping with the IM 650 is possible:
● For digital input signals of modules from the S7-300 series of modules. Signals of ET 200PA
SMART input modules are not time stamped.
● With the PCS 7 system solution using the IMDRV_TS block.
For a detailed description of time stamping, refer to manual PCS 7 Process Control System
