Because the CPM2C-MAD11 Analog I/O Unit and the CPM2C-TS001/101Temperature Sensor Units require 2 I/O words each, only 4 of these Unitscan be connected to the PC.
(The CPU Unit itself requires one input wordand one output word.) A different Unit, such as an Expansion I/O Unit or theCPM2C-SRT21 CompoBus/S I/O Link Unit, can, however, be connected inaddition to 4 Analog I/O Units or Temperature Sensor Units.Analog I/O UnitCPM2C-MAD112 analog inputsInput 0: word (m+1)Input 1: word (m+2)1 analog outputOutput 0: word (n+1)Temperature Sensor UnitsCPM2C-TS001/TS1012 temperature inputsInput 0: word (m+1)Input 1: word (m+2)No outputsCompoBus/S I/O Link UnitCPM2C-SRT218 inputsInput: word (m+1)8 outputsOutput: word (n+1)Note Input bits 00 to 07 in word (m+1) are for outputs from the Master. Output bits 00 to07 in word (n+1), are for inputs to the Master.5-3-4 Examples of Expansion Unit and Expansion I/O Unit AllocationUp to 5 Expansion Units or Expansion I/O Units can be connected to a CPM2CPC.
Input bits and output bits are automatically allocated starting from the CPUUnit and continuing through Expansion Units and Expansion I/O Units in theorder in which they are connected. The input area consists of the 10 words fromIR 000 to 009, and the output area consists of the 10 words from IR 010 to 019.Although I/O bits are allocated automatically, it is necessary to ensure that boththe number of input words and the number of output words do not exceed 10. Forexample, the Analog I/O Unit and Temperature Sensor Unit require 2 inputwords and so it is not possible to connect 5 of these Units.299SectionI/O Allocation for CPM2C PCs5-3Example: CPU Unit with 20 I/O Points + Expansion I/O Unit with 24 I/O PointsCPU Unit(20 I/O points)Expansion I/O Unit(24 I/O points)12 inputsIR 00000toIR 0001116 inputsIR 00100toIR 001158 outputsIR 01000toIR 010078 outputsIR 01100toIR 0110715Bits14IR 000Inputs1312111009080706050403020100Do not useIR 001IR 010OutputsIR 011Example: CPU Unit with 20 I/O Points + 5 Expansion I/O Units with 24 I/O PointsExpansion I/O Unit(24 I/O points)Expansion I/O Unit(24 I/O points)12 inputsIR 00000toIR 0001116 inputsIR 00100toIR 0011516 inputsIR 00200toIR 002158 outputsIR 01000toIR 010078 outputsIR 01100toIR 011078 outputsIR 01200toIR 01207CPU Unit(20 I/O points)Bits15IR 000IR 001InputsIR 002IR 003IR 004IR 005IR 010IR 011Outputs IR 012IR 013IR 014IR 0153001413Do not use12111009Expansion I/O Unit(24 I/O points)Expansion I/O Unit(24 I/O points)16 inputsIR 00300toIR 0031516 inputsIR 00400toIR 0041516 inputsIR 00500toIR 005158 outputsIR 01300toIR 013078 outputsIR 01400toIR 014078 outputsIR 01500toIR 01507Expansion I/O Unit(24 I/O points)080706050403020100SectionI/O Allocation for CPM2C PCs5-3Example: Configuration Including Expansion I/O Units and a CompoBus/S I/O Link UnitCPU Unit(20 I/O points)12 inputsIR 00000toIR 00011Expansion I/O Unit(16 input points)Expansion I/O Unit(16 input points)16 inputsIR 00100toIR 0011516 inputsIR 00200toIR 002158 outputsIR 01000toIR 01007No outputsBits15IR 000Inputs141311Expansion I/O Unit(16 output points)No inputs1009080716 outputsIR 01200toIR 01215060504CompoBus/S I/OLink Unit8 inputsIR 00300toIR 00307No inputs16 outputsIR 01100toIR 01115No outputs12Expansion I/O Unit(16 output points)8 outputsIR 01300toIR 0130703020100Do not useIR 001IR 002IR 003Do not useIR 010IR 011OutputsIR 012IR 013301SectionI/O Allocation for CPM2C PCs5-3Example: Configuration Including Analog I/O Units, Temperature Sensor Units, and Expansion I/O UnitCPU Unit(20 I/O points)Analog I/O Unit 1CPM2C-MAD1112 inputsIR 00000toIR 000112 analog inputsInput 0: IR 001Input 1: IR 0028 outputsIR 01000toIR 010071 analog outputOutput: IR 01115BitsIR 000Inputs1413Temperature SensorUnit 1CPM2C-TS0012 temperature inputsInput 0: IR 003Input 1: IR 00411102 analog inputsInput 0: IR 005Input 1: IR 006Temperature SensorUnit 2CPM2C-TS1012 temperature inputsInput 0: IR 007Input 1: IR 0081 analog outputOutput: word 012No outputs12Analog I/O Unit 2CPM2C-MAD11090807No outputs06Do not useIR 001Used for input 0 of Analog I/O Unit 1IR 002Used for input 1 of Analog I/O Unit 1IR 003Used for input 0 of Temperature Sensor Unit 1IR 004Used for input 1 of Temperature Sensor Unit 1IR 005Used for input 0 of Analog I/O Unit 2IR 006Used for input 1 of Analog I/O Unit 2IR 007Used for input 0 of Temperature Sensor Unit 2IR 008Used for input 1 of Temperature Sensor Unit 2IR 009IR 010OutputsIR 011Used for the output of Analog I/O Unit 1IR 012Used for the output of Analog I/O Unit 2IR 013302050403Expansion I/O Unit(24 I/O points)16 inputsIR 00900toIR 009158 outputsIR 01300toIR 01307020100SECTION 6Ladder-diagram ProgrammingThis section explains the basic steps and concepts involved in writing a basic ladder diagram program.
