running a KUKA KR 5 ARC (KR C4 controller) in T1 and auto mode

Dear experts,

I have recently started to learn about robots and got a KUKA KR 5ARC with KR C4 controller to start. After acknowledging some error messages I am able to operate all the axes in start up mode but I couldn't put the robot in T1 and auto modes. It seems the reason is that the robot controller has been configured to work along with a PLC and as there is not any plc available now it is not able to receive the enabling signals and so the aforementioned modes are not selectable . Can somebody please help me about linking a plc like S7 1200 or 1500 to the robot controller and guide me about the signals which are required to be issued from the PLC. And one more question, how can I operate the robot in auto or T1 without connecting a PLC i.e. bypassing the safety signals? To be more clear the messages I get in the robot HMI are as follow (unfortunately I couldn't upload the images):

KSS02858 Stop due to field bus error

KSS15009 Profisafe communication error

KSS11011 Connection between PLC and KMZ11-20R10 could not be established in 2000ms

KSS01033 error on reading, driver: PNIO-DEV

KSS01034 error on writing, driver: PNIO-DEV

Thanks for your help.

Quote from panic mode

your robot system seem has ProfiSafe as safety interface

This means there is no way to use the robot without Safety PLC which of course must be a ProfiNet and ProfiSafe master and have matching configuration. I think the lowest cost option is to add small safety PLC like S7-1200F. but things get more expensive when one adds safety IO cards

Thanks for the response , so could you please guide me about the corresponding safety signals or let me know about documents needed for this purpose? And one more question, is it possible to reconfigure the robot using work visual to run the robot without a PLC or using new safety signals.

Thanks

could you please give me the name of manuals for safety and configuration or the links to download .

many thanks.

many thanks for your help. But unfortunately I don't access to kuka portal ,Xpert (cause it requires to use a company email which I don't have) .I found some of the manuals but I couldn't find CWRITE, optional interfaces and Configuration of Kinematic systems manuals. could you please upload or let me know where I can download those?
