Parameters Of Sm 321; Di 16 X Dc 24/125 V - Siemens SIMATIC Manual

Digital modules
3.12 Digital input module SM 321; DI 16 x DC 24/125 V; with hardware and diagnostic interrupts (6ES7321-
7EH00-0AB0)
Configuration in RUN
Special considerations must be given if you use the Configuration in RUN function.
SF LED is lit:
Status before re-configuration diagnostics on, SF LEDs lit among others (on CPU, IM or
module), although diagnostics are no longer pending and the module is operating correctly.
Solution:
● Only change the configuration when no diagnostics are pending for the module or
● Pulling and plugging the module.
