Hint
• The setting in bit 1 of C+5 is supported only by CJ2, CJ1, CS1-H, CJ1-H CPU Units and CS1 CPU
Units with lot numbers of 001201@@@@ or later (manufactured December 1, 2000 or later).
• The number of valid input data bits for the measured value is designated by the input range setting in
C+6, bits 08 to 11, and the number of valid output data bits for the manipulated variable output is
designated by the output range setting in C+6, bits 0 to 3. These ranges are shown in the following
table.
If the range of data handled by an Analog Input Unit or Analog Output Unit cannot be set accurately
by setting the number of valid bits, APR(069) (ARITHMETIC PROCESS) can be used to convert to
the proper ranges before and after PID(190).
The following program section shows an example for a DRT1-AD04 Analog Input Unit and DRT1-
DA02 Analog Output Unit operating as DeviceNet slaves. The data ranges for these two Units is 0000
to 1770 hex, which cannot be specified merely by setting the valid number of digits. APR(069) is thus
used to convert the 0000 to 1770 hex range of the Analog Input Unit to 0000 to FFFF hex for input to
PID(190) and then the manipulated variable output from PID(190) is converted back to the range
0000 to 1770 hex, again using APR(069), for output from the Analog Output Unit.
