Analog output data will be 0 V or 0 mA until the range code has been written. After therange code has been written, the analog output data will be 0 V or 0 mA if therange is 0 to 10 V, –10 to 10 V, or 0 to 20 mA, or it will be 1 V or 4 mA if the range is1 to 5 V or 4 to 20 mA.SR 25315(Always ON Flag)TIM 005#0002T005MOV (21)TIM 005 will start as soon as power turns ON.After 0.1 to 0.2 s (100 to 200 ms), the Completion Flag for TIM 005 will turn ON, and the converted data from analog input will be read fromIR 001 and stored in DM 0000.001DM0000Handling Unit ErrorsIf an error occurs in an Analog I/O Unit, the Error Flags in AR 0200 to AR 0204 willbe turned ON.
The addresses of the Error Flags are in the order that the Expansion Units and Expansion I/O Units are connected in the PC, with AR 0200 usedfor the Expansion Unit or Expansion I/O Unit closest to the CPU Unit. Use theseflags in the program when it is necessary to detect errors.When an error occurs in the Analog I/O Unit, analog input data will be 0000 and0 V or 0 mA will be output as the analog output.If a CPU error or an I/O bus error (fatal errors) occurs at the CPU Unit and theanalog output is set to 1 to 5 V or 4 to 20 mA, 0 V or 0 mA will be output. For anyother fatal errors at the CPU Unit, 1 V or 4 mA will be output.174SectionAnalog I/O Units3-1Programming ExampleThis programming example uses these ranges:Analog input 0: 0 to 10 VAnalog input 1: 4 to 20 mAAnalog output: 0 to 10 V25135(First Cycle ON Flag)MOV (21)805101125313(Always ON Flag)Writes the range code (8051) to the Unit.TIM 005TIM005#0002ExecutionconditionMOV (21)001TIM005DM0000ExecutionconditionReads analog input 0’s converted value.CMP (20)002#800025506(=)01000TIM005Open-circuit alarmExecutionconditionMOV (21)002TIM005DM0001ExecutionconditionReads analog input 1’s converted value.MOV (21)DM0010011The content of DM 0010 is written to the outputword as the analog output set value.175SectionTemperature Sensor Units3-23-2Temperature Sensor Units3-2-1 CPM1A/CPM2A Temperature Sensor UnitsWith the CPM1A or CPM2A, up to three Expansion Units or Expansion I/O Unitscan be connected to the CPU Unit.
One, two, or three of these Units can beCPM1A-TS001 or CPM1A-TS101 Temperature Sensor Units. If a CPM1ATS002 or CPM1A-TS102 Temperature Sensor Unit is connected to the CPUUnit, then only one other Expansion Unit or Expansion I/O Unit can be connected. The other Unit can be a CPM1A-TS001/TS101 Temperature SensorUnit.The CPM1A-TS001/TS101 Temperature Sensor Units each provide 2 inputpoints and the CPM1A-TS002/TS102 Temperature Sensor Units each provide 4input points, meaning up to 6 temperature input points can be used on oneCPM1A or CPM2A PC. The inputs can be from thermocouples or platinum resistance thermometers.Up to 3 Units, including Expansion I/O Units and other ExpansionUnits.
