Analog Voltage Output Updating a Pair You can also update just a pair of channels in a single scan by using the Immediate of Channels in instructions found in the D4–440 and D4–450 CPUs. By removing the FOR–NEXT a Single Scan, rungs and a couple of other rungs, we create the example below.

Analog Voltage Output Analog and Sometimes it is helpful to be able to quickly convert between the voltage or current Digital Value signal levels and the digital values. This is especially useful during machine startup Conversions or troubleshooting. The following table provides formulas to make this conversion easier.

A–2 DL405 Discrete I/O Memory Map The following tables provide the discrete memory map for the DL405 CPUs. These are especially helpful since DL405 Analog modules utilize discrete input and output points. Also, there are some occasions where you use control relays to sequence the program logic that updates the analog data. If you need additional memory map information, see the DL405 User Manual.
