5.6Programming a Restart or Warm Restart

A restart of the MOBYIM (interface module) is carried out by setting the variable "init_run". With "init_run“, the IM and FB45 are re-parameterized and synchronized.

"init_run“ is necessary after the following:

•Switching on the SIMATIC (OB 100)

•Switching on the power supply for the IM

•PROFINET communication is interrupted

•An error indication by the variable "error_BUS"

•A transponder type change; for example from RF300 to ISO or vice versa

•Changing an INPUT parameter in DB45 (Reader_Parameter)

Generating OB100

Open OB100 and enter the program

Save and close OB100
