Hello,
I'm working on a project where I want to communicate with two GP230 drivers using a S7-1200 (1214 DC/DC/Rly) with a 1243-5 profibus master.
The drivers include the profibus communication and I wired everyting.
The problem comes when I download the HW configuration. I already check everything (part numbers, power supplies, etc.) and everything is OK, but once I download the configuration I get the errors attached on the images (sorry they're in spanish), but basically:
One image shows the local moduls, all of them are OK, but the PLC appears in error, this because the CM 1243-5 card is in error.
When I go to the Online and Diagnosis of this card (the other picture), I get the following errors:
No acccesible
There is a difference between downloaded configuration and the offline project.
Reference online: ?
Reference offline: 6GK7 243-5DX30-0EX0
I already checked and the part number of the card is ok, it is wired correctly, the profibus has the resistance on the extremes (the ON is selected on the profibus connector), but the LED of the card is on red.
What do you suggest I should do?, I've tryed everything I can think of without any success.
Hope you can help me-
Best regards
Juan
