964 List Manual (LH8), 02/2015, 6RX1800-0ED76
A08520 (F) PN/COMM BOARD: Non-cyclic channel error
Message value: %1
Message class: Communication error to the higher-level control system (9)
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The memory or the buffer status of the non-cyclic channel has an error.
Alarm value (r2124, interpret decimal):
0: Error in the buffer status.
1: Error in the memory.
Remedy: Check communications link.
Reaction upon F: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY
A08526 (F) PN/COMM BOARD: No cyclic connection
Message value: -
Message class: Communication error to the higher-level control system (9)
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: There is no cyclic connection to the control.
Remedy: Establish the cyclic connection and activate the control with cyclic operation.
For PROFINET, check the parameters "Name of Station" and "IP of Station" (r61000, r61001).
If a CBE20 is inserted and PROFIBUS is to communicate via PZD Interface 1, then this must be parameterized using
the STARTER commissioning tool or directly using p8839.
Reaction upon F: NONE (OFF1)
Acknowl. upon F: IMMEDIATELY
A08530 (F) PN/COMM BOARD: Message channel error
Message value: %1
Message class: Communication error to the higher-level control system (9)
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The memory or the buffer status of the message channel has an error.
Alarm value (r2124, interpret decimal):
0: Error in the buffer status.
1: Error in the memory.
Remedy: Check communications link.
Reaction upon F: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY
A08550 PZD Interface Hardware assignment error
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: CU_DC, CU_DC_R, CU_DC_R_S, CU_DC_S
Reaction: NONE
Acknowledge: NONE
Cause: The assignment of the hardware to the PZD interface has been incorrectly parameterized.
Alarm value (r2124, interpret decimal):
3: Assigned COMM BOARD missing.
See also: p8839 (PZD interface hardware assignment)
Remedy: Check the parameterization and if required, correct (p8839).
