WildChild Posts: 26 Rating: (0)	Hello, I'm new programming Siemens devices, and I have a lot of questions. Could you help me please? I'm using CPU315-2PN/DP and a Micromaster420 Profibus network (10 devices). I'm trying to control de MMs with FC14 (following the FC14_Profibus_DP_en example). The questions: 1. Is it possible to control all the micromaster by Profibus using different FCs and defining different UDTs? 2. I need to ON/OFF the micromaster with a digital input, but I need to control the frec. by Profibus.Is it possible?How? 3. Could you explain me the FC14 inputs/outputs? CALL FC 14 hw_config_I_O_address:=256 drive_on_off :="drive_on_off" drive_reversing :="drive_reversing" drive_fault_ackn :="drive_fault_ack" drive_f_setpoint :="drive_f_set" drive_in_operation :="drive_in_operation" drive_fault_active :="drive_fault" drive_alarm_active :="drive_alarm" drive_f_act :="drive_f_act" I suppose this questions are easy but I'm lost. Thank you very much! WildChild
