Dears. I have issue with our Simotin D425.Today I  get part of the line stopped by the simotion D425. All 4 axixs  controlers had errors led on as well as  SMC30 controlers .   I have old project unfortuanetly from 2016  and I had 2 or 3 scouts updates so I cannot connect with full  compatibility but at least I could do Diagnostitic buffer check. Here is list of errors from one  stop.  Any advices how to finad the reason for such a behaviour ? It looks like some general error because 9 modules get error.  CPU  and power supply seems to be fine, only RDY led on D425  lights in red .  

I found some manual and description is :

Device 1    0x8000h DP: Life-sign of drive has malfunctioned or failed

Device 2 DP: 0x8000h Life-sign of encoder has malfunctioned or failed.
(note: for an encoder whose data are transferred in a drive telegram together
with actuator data, the actuator life-sign applies to the encoder, e.g. for standard
telegram 3 in accordance with PROFIdrive)

It looks as problem with profibus …  Strange because comunication between the modules is DriveCliq  Should i consider also Drivecliq or concentrate on Probibus ?
