Table 8.B – SMC Status Data
Reference/Feedback The SMC Dialog Plus controller does not support the analog reference
feature of SCANport. However, the SCANport analog feedback feature is
supported. The feedback word will always be equal to Parameter
number 4, Current Phase A.
Parameter Listing Refer to Appendix B, Table B.1 for a complete listing of the SMC Dialog
Plus controller's parameters and groups. In addition to the range of
adjustments, the parameters' units are provided.
Scale Factor Conversion The parameter values of the SMC Dialog Plus controller are stored as
unscaled numbers. When reading parameter data in the PLC/SLC's input
image table, divide this number by the scale factor shown in Appendix B,
Table B.1 to arrive at the proper value.
When writing from the PLC/SLC's output image table to the SMC Dialog
Plus controller, the scale factor must be taken into consideration to ensure
that the proper value is sent.
