Reading the Process Value
Summary
This program reads each loop’s process value (PV) data and stores the data in a DM Area word (D00100 to
D00103 for loops 1 to 4). Each loop’s input value is read by the MOV Instruction when the loop’s Sensor Error
Flag is OFF.
Example Unit Settings
• Unit: CJ1W-TC001 Temperature Control Unit
• Unit number: 00
Note The unit number switches are on the front of the Unit. Refer to 2-3-3 Unit Number Switches for details.
Example Program
The Sensor Error Flags are in bit 14 of CIO (n+8), CIO (n+9), CIO (n+18), and CIO (n+19).
