Allen-Bradley ProcessLogix 1757 Series User Manual

Publication 1757-RM810A-EN-P - May 2002
3-58 Functional Blocks
Outputs Block has the following initializable outputs:
• OP = Calculated output in percent.
• OPEU = Calculated output in engineering units.
– User may specify a fixed bias to be added to the output.
– Block calculates floating bias to provide bumpless transition after input switching, initialization or mode
change.
Note that the default OP connection pin is exposed on the blocks and the implicit/hidden connection function
automatically makes the appropriate value/status parameter (OPX/OPEUX) connection when required.
Output Ranges • CVEUHI and CVEULO define full range of CV in engineering units. If block has no secondary, CVEUHI and CVEULO
track the “X” input range (XEUHI and XEULO).
• OPHILM and OPLOLM define normal high and low limits for OP as a percent of CV range (user-specified values).
• OPEXHILM and OPEXLOLM define extended high and low limits for OP as a percent of CV range (user-specified).
– Prevents operator from storing an OP that exceeds these limits.
