Slave-life sign limit (P-AXIS-00162)

Limit to monitor the slave life sign. In the PROFIDRIVE telegram a life sign is transmitted, which is implemented as a per cycle incremented counter. If the counter value from the telegram is not equal to the value expected from the NC-kernel an internal error counter is incremented by 10. Everytime the transmitted counter value and the expected value are equal the error counter is decremented by one. If the error counter exceeds s_ls_limit an error message with number P-ERR-70106 (Life sign from PROFIBUS slave missing) is given out.
