Writing Theanalogvalue - Siemens SIMATIC S5 1P 243 Equipment Manual

Programming Instructions
When the analog routing operations have been performed in single steps so far, they now must be
supplemented by the following jumpers:
– >
(PIN 21) (PIN 25)
–>
(PIN 26)
(PIN 22)
(PIN 27)
(PIN 23)
Via the programmer function "Control variable" a value can be specified via flag word FW 12 which
is output as an analog value. If input 14.0 (NORM) has signal status"1", the value can be output in
then directly transferred to the module.
In order to determine the written analog value, it is measured at the contacts in the front connector
of the analog module (e.g., pin 28 for AO1 and pin 33 for potential).
