Exchanging Data with the CPU Unit Section 3-5
Set Values and Stored Values
Note 1. The input signal range of “1 to 5 V” and “4 to 20 mA” is switched using the
pins of the voltage/current switch. Refer to 3-3-4 Voltage/Current Switch for
details.
2. The default of mean value processing setting is set to “Mean value pro-
cessing for 2 buffers.” Refer to 3-6-3 Mean Value Processing.
3-5-5 I/O Refresh Data Allocations
I/O refresh data for the Analog Input Unit is exchanged according to the allo-
cations in the Special I/O Unit Area.
Note 1. The Special I/O Unit Area words that are occupied by the Analog Input Unit
are set using the unit number switch on the front panel of the Unit. Refer to
3-5-2 Unit Number Settings for details on the method used to set the unit
number switch.
