The individual error indications are described below. Most of the errors indicate fatal hardware errors, requiring that the PM810 must be replaced. The reasons why the communication interface of the PM810 is not in operation are: • Wrong number of cables. Single media configured and redundant used or redundant media configured and single used. • Several stations are using the same station number. • The station number defined in data base differs from the value defined on the address switch on the front panel of the PM810 module. • The bus number defined in data base differs from value defined on BUSNO terminal on CI520/CI522 data base element or the bus terminal on the CI626/CI627 data base element. • If the bus is not terminated, it will not work properly. If the data base is correctly defined and correct address is set on PM810 a rough way to restart the module is to perform an init on the module. If this does not help, replace the module.
In Operation with Error Indications
The background supervision of Advant Controller 70 automatically detects some errors on the communication interface of the processor module PM810 and gives a summary error message “Errors during BAP access” visible in the error report which is provided by Advant Station 100 Series engineering station. By means of the diagnosis tool, more detailed error messages are available. A list of all possible error messages for the PM810 is shown in Table 49. If the Advant Controller 70 is supervised from an Advant Controller 400 Series the status information is also displayed on the DIAG terminal on the Advant Controller 70 data base element.
Error Detection In S800 I/O Station
CI810 cannot detect many of the errors that CI520/CI522 or CI626/CI627 detects because it is only a slave on the Advant Fieldbus 100. Moreover the communication interface of the CI810 cannot be separately restarted, if a serious error occurs CI810 stops and remains in error state. The individual error indications are described below. Most of the errors indicate fatal hardware errors, requiring that the communication interface must be replaced. The reasons why the CI810 is not in operation are: • The CI810 data base element terminal IMPL/SERVICE is set to zero. • The module is out of order. • Single media configured and redundant used or redundant media configured and single used. • Several stations are using the same station number.
