Hello Community,

I've been facing a technical problem these couple of days to start  SFC externally (not through faceplate)

While reading Compendium Part C chapter 8 " 8.1 State change", it mention that is possible to start the SFC in auto mode by means of automatic interface.

The problem that I have is that the "START, ENSTART, ENASTART" are all true while the operating mode is Auto (please see attached file.JPG) but the State of SFC is stuck at IDLE.
Also in the start condition of the sequencer I've tried them (Start, Starting, Run) but  not efficient to be able to start the SFC externally through the click of button and change from IDLE to RUN

P.S from the faceplate I can start it normally and the state change from IDLE to RUN.

The project that I'm working on is ES/OS station with PCS 7 V9.1 SP2.
CFC: V9.0 + SP7
SFC: V9.0 + SP7

AutoGen_6623319

Take a look at the SFC properties in the SFC editor (from menu). There is a drop down that should be set to Auto. Then set (or verify) in CFC editor online that top left interconnect AUT is "1".

I did not use ENASTART, just ENSTART. There is logic driving "START". Check error outputs in CFC. There is a code that tells that parameters are incorrect in case too many inputs to the block are set.

 Thank you AutoGen_6623319 for your reply.

I followed the mentioned steps and changed the "operating mode" from Manual to Auto on the combo box option.
This changes only made the SFC in Auto mode when starting up but I wasn't able to start the sequence via "START".

Any other propositions ?
Many thanx in advance. 

Hello Oreca,

Thank you for your reply!

I don't have control strategies or set points but I have some parameters and the initial values are zeros.
the value for LI_ERR and LI_ERR_State is zero as shown in the attached picture.

If you need more screen shots or data please don't hesitate to ask.

Many thanks in advance.
