4 OPERATION
Remote Display Controller Input (RDCI) and Get Numeric (GETN)
The input channel number will be in decimal notation. The associated
interfaced PLC register is the PAC channel number plus 3500.
The input item number is not used by the Square D PLC gateway.
The output channel number will be in decimal notation. The associated
interfaced PLC register is the PAC channel number plus 3500.
The output item number is not used by the Square D PLC gateway.
The function number is used to identify the data in the PAC diagram. The
PLC programmer does not need to use this number.
The minimum and maximum values are used for numeric limit checking at the
source. Each source of data is required to check that limits are not exceeded
when new data is to be presented to the GETN or RDCI PAC block. This limit
checking is preformed by the PLC gateway. If the PLC sends new data to the
PLC gateway that exceeds the limit, then the data is simply discarded and not
sent to the drive.
The decimal point location parameter is required.
