SDMAO4
Sets output voltage levels in an SDM‐AO4 analog output device.
Syntax
SDMAO4(Source, Reps, SDMAdress)
SDMAO4A
Sets output voltage levels in an SDM‐AO4A analog output device.
Syntax
SDMAO4A(Source, Reps, SDMAdress)
SDMCAN
Reads and controls an SDM‐CAN interface.
Syntax
SDMCAN(Dest, SDMAddress, TimeQuanta, TSEG1, TSEG2, ID,
DataType,
SDMCD16AC
Controls an SDM‐CD16AC, SDM‐CD16, or SDM‐CD16D control device.
Syntax
SDMCD16AC(Source, Reps, SDMAddress)
SDMCD16Mask
Controls an SDM‐CD16AC, SDM‐CD16, or SDM‐CD16D control device. Unlike the
SDMCD16AC, it allows the CR800 to select the ports to activate via a mask.
Commonly used with TimedControl().
Syntax
SDMCD16Mask(Source, Mask, SDMAddress)
SDMCVO4
Control the SDM‐CVO4 four‐channel, current/voltage output device.
Syntax
SDMCVO4(CVO4Source, CVO4Reps, SDMAddress, CVO4Mode)
SDMGeneric
Sends commands to an SDM device that is otherwise unsupported in the
operating system.
Syntax
SDMGeneric(Dest, SDMAddress, CmdByte, NumvaluesOut, Source,
NumValuesIn, BytesPerValue, BigEndian, DelayByte)
SDMINT8
Controls and reads an SDM‐INT8.
Syntax
SDMINT8(Dest, Address, Config8_5, Config4_1, Funct8_5,
Funct4_1, OutputOpt, CaptureTrig, Mult, Offset)
SDMIO16
Sets up and measures an SDM‐IO16 control‐port expansion device.
Syntax
SDMIO16(Dest, Status, Address, Command, Mode Ports 16-13,
Mode Ports 12-9, Mode Ports 8-5, Mode Ports 4-1, Mult,
Offset)
