Parameters: %1 = Conflict type %2 = Serial number within a conflict sequence %3 = Number of the affected bus Definitions: An access conflict occurred on the PROFIBUS/PROFINET in cyclic mode: An attempt has been made in the NCK to write data to the bus or to read from the bus while cyclic data transfer was active. This may lead to inconsistant data. Type 1: NCK attempts to read data before th e cyclic transfer has finished on the bus. Type 2: The NCK has not finished writing its data when the cyclic transfer begins again. Counter %2 contains a serial number starting at 1. A maximum of 10 alarms are output in succession. If no conflicts occur in a DP cycle, the counter is reset and new alarms are output again on the next conflict. Reaction: Alarm display. Drives alarms Remedy: - Check the timing again, in particular ensure that the settings in MD10050 $MN_SYSCLOCK_CYCLE_TIME and MD10062 $M N_POSCTRL_CYCLE_DELAY are correct: MD10062 $MN_POSCTRL_CYCLE_DELAY must be larger for type 1. MD10062 $MN_POSCTRL_CYCLE_DELAY must be smaller for type 2. - If alarm-free operation cannot be achieved with any MD10062 $MN_POSCTRL_CYCLE_DELAY setting, MD10050 $MN_SYSCLOCK_CYCLE_TIME must be increased. - If the error cannot be eliminated by this procedure, please make a note of the error text and contact the control system manufacturer. Program Continuation: Clear alarm with the Delete key or NC START.
