4. Use the peripheral device to monitor the word to which the analog input
data to be adjusted is stored. The CQM1H/CQM1 can be in any mode. The
analog input conversion data will be the lower-limit value.
5. Apply the same method to the analog input’s maximum value to obtain the
upper-limit value.
6. Create the following program to scale values in a range between the lower
and upper-limit values and designate the lower- and upper-limit values that
have been monitored as parameters. Refer to page 96, Scaling for details.
–10 to 10 V If the Analog Input Unit is set to a range of –10 to 10 V, follow the steps
described below to adjust the Analog Input Unit.
1,2,3... 1. Refer to 3-1 Settings and connect the Analog Input Unit, CPU, and sensor
or transducer.
2. Connect a peripheral device such as a Programming Console to the CPU
and while referring to 3-3-1 Programming, create a program to convert 2’s
complement.
