Explanation:
Overflow of DP in-/output data buffer: The number of the input and
output data bytes recognized at the peripheral bus is higher than the
number that can be transmitted via the PROFIBUS-DP.
Overflow of DP input data buffer: The number of the input data bytes
recognized at the peripheral bus is higher than the number that can be
transmitted via the PROFIBUS-DP.
Overflow of DP output data buffer: The number of the output data
bytes recognized at the peripheral bus is higher than the number that can
be transmitted via the PROFIBUS-DP.
No I/O assignment found: No I/O module could be recognized at the
peripheral bus.
General peripheral bus error
1
: Possible causes for errors are:
• Plugging or unplugging an I/O module during operation.
• Missing 24 V power supply of the POS-SA 1/2 module.
Peripheral bus time out
1
: An I/O module at the peripheral bus delays
access via the permissible value. A possible cause for the error might be
a defective I/O module.
