Turn ON AR 2115 (Clock Set Bit) when the time set in step 2 is reached. Theclock will start operating from the time that is set, and the Clock Stop Bit andClock Set BIt will be turned OFF automatically.Setting Only the SecondsIt is also possible, by using AR 2113, to simply set the seconds to “00” withoutgoing through a complicated procedure. When AR 2113 is turned ON, the clocktime will change as follows:If the seconds setting is from 00 to 29, the seconds will be reset to “00” and theminute setting will remain the same.If the seconds setting is from 30 to 59, the seconds will be reset to “00” and theminute setting will advance by one.When the time setting is complete, AR 2113 will turn OFF automatically.Note The time can be set easily using menu operations from a Programming Consoleor SSS.
Refer to the CPM2A Operation Manual or the CPM2C Operation Manual for the Programming Console procedure or to the SSS Operation Manual: Cseries PCs for the SSS procedure.151SECTION 3Using Expansion UnitsThis section describes how to use the CPM1A-MAD01 and CPM2C-MAD11 Analog I/O Units, theCPM1A-TS001/002/101/102 and CPM2C-TS001/101 Temperature Sensor Units, and the CPM1A-SRT21 and CPM2CSRT21 CompoBus/S I/O Link Units.3-13-23-3Analog I/O Units . . . .

One Analog I/O Unit allows 2 analog inputs and 1 analog output.With the maximum of 3 Analog I/O Units connected, 6 analog inputs and 3 analog outputs are possible.• The analog input range can be set to 0 to 10 VDC, 1 to 5 VDC, or 4 to 20 mAwith a resolution of 1/256.• An open-circuit detection function can be used with the 1 to 5 VDC and 4 to20 mA settings.• The analog output range can be set to 0 to 10 VDC, 4 to 20 mA, or –10 to10 VDC.
The output has a resolution of 1/256 when the range is set to 0 to10 VDC or 4 to 20 mA, or a resolution of 1/512 when set to –10 to 10 VDC.A maximum of 3 Expansion Units or Expansion I/O Units can be connected.CPM1A-8EDCPM1A-MAD01Expansion I/O Unit Analog I/O Unit2 analog inputsCPM1A-20EDR1Expansion I/O Unit1 analog outputCPM1(-V1)/CPM1A/CPM2ACPU UnitNote The CPM1-30CDR--V1 is the only CPM1 CPU Unit to which 3 ExpansionUnits or Expansion I/O Units can be connected. Only one Expansion Unit orExpansion I/O Unit can be connected to models without the “V1” suffix. AnalogUnits cannot be connected to 10-point or 20-point CPM1A CPU Units.

With analog outputs it is possible to use both voltage outputs and currentoutputs at the same time. In this case however, the total output current mustnot exceed 21 mA.2.

To change the I/O range, turn the CPUUnit OFF then ON again.Note If a range code other than those specified in the above table is written to n+1, therange code will not be received by the Analog I/O Unit and analog I/O conversionwill not start.Analog I/O UnitConnectionThis section describes how to connect an Analog I/O Unit to the CPU Unit.A maximum of 3 Expansion Units or Expansion I/O Units, including Analog I/OUnits, can be connected to one PC. When the Analog I/O Unit is used in combination with other Expansion Units or Expansion I/O Units, there are no restrictions on the connection order.Analog I/O UnitCPM1/CPM1A/CPM2ACPU UnitI/O AllocationI/O is allocated for the Analog I/O Unit in the same way as other Expansion Unitsor Expansion I/O Units starting from the next word following the last allocatedword on the CPU Unit, or previous Expansion Unit or Expansion I/O Unit.
