ABB PFRL101C Vertical measurement sensor

The penultimate parameter in the block structure must be the status word, as for the OS interprets the parameter (S16 string minus 1) as status word. The status word parameter type must be PA. Its contents are read during initialization and used for updating the OS. Any number of binary and analog values can be controlled by the OS if this structure is observed. Operator input logging is performed in the same fashion as for standard function blocks. User function blocks which do not possess an S16 string as the last parameter can also be controlled without these conventions being observed. A simplified operator input is then generated.

Error Messages with Bus Condition Codes 

There are two different condition groups generating bus condition codes: 1. Bus redundancy condition codes 2. Job–related condition codes The following messages/faults can be identified within these groups Each redundancy condition code causes an I&C alarm which is only output on the printer.  The N8/N–AS only signals 8 redundancy changeovers within 30 minutes. The BT.STAT status displayed may therefore not be up to date. The UI always shows the latest status.The group bit is set in GB.ORPA.9 and the condition code word in GA.ORPA.27 transferred if a condition code occurs. GA27 always contains the latest condition code. A system fault message is also generated.

Safety-Related Symbols 

The following symbols are used in this manual according to the safety-related content. Be sure to observe text annotated with these safety symbols as their content is important. Mis-operation may result in a hazardous condition with the possibility of death or serious injury.
