[etherlab-users] WG: possible master problems

[Olaf Holowenko]

Hi Ian, 

 

>> static ec_pdo_info_t el3102_pdos[] = {

>>    {0x1c12, 2, el3102_pdo_entries},

>> };

 

Why 0x1c12? Try 0x1A** / 0x16** for input / output.

 

Regards, Olaf

Betreff: [etherlab-users] possible master problems

 

Hi, 

We are trying to implemt a master on Linux to drive a Kollmorgen s300 drive
and a Festo CPX pnuematic node. 

Both devices (slaves ) appear to show the same symptoms of dropping into
PREOP state as soon as our user code establishes a master connection,
defines a PDO and begins to write data, regardless of the data.

The Servostar s300 shows errors F23 and N17 which relate to CAN errors which
translate to -: Drive tries to establish communication, but there is no
other node, or CAN nodes have different baud rates, bus cable defect,
reflections because of missing or wrong bus terminators!, or CAN sync is not
logged in, or CAN sync is activated, but is not sent synchronously from the
controller, if at all!

I have been to Festo (UK) and they could not resolve my problem and pointed
to the Master as being at fault? 

Have you any ideas please? We are getting quite desperate now! 

Attached is my user code. <<main.c>> 

regards 
Ian
