SINA_PARA and V14SP1 another trouble

I have tested SINA_PARA to read 5 parameters from an V90 Profinet drive.

After some trials SINA_PARA with single instance DB  programmed as:

start              1Hz clock

ReadWrite    0

ParaNo          5

AxisNo          16#02

hardwareId    276

works fine.

Using the same harware, same parameters but programming SINA_PARA with multi istance DB and with the hardwareId passed by the calling block the errorId is 16#0000_0000, but no parameters are read fron the drive.

This change is done because the system will have 8 V90 Profidrive to handle, so I will make an OB for every drive whith the proper parameters.

May be something related to the AxisNo ?

Yours Sincerely,

Pier Giovanni

I don't know the SINAMICS V90 in detail, but all other SINAMICS can only handle one parameter transfer at one time.

So make a cascade and start the next parameter transfer when the previous has finished.

Hi,

I have used the hardware ID instead of the Module Access Ponit ID.

Now the drive work.

Starting SINA_PARA one at a  time seems to be a good idea, i will now implement a programm to scan them in sequence.

Yours Sincerely,

Pier Giovanni
