Notation of Unit Versions on Products The unit version is given to the right of the lot number on the nameplate of the products for which unit versions are being managed, as shown below. Confirming Unit Versions with Support Software CX-Programmer version 9.4 or higher can be used to confirm the unit version of the CP1L-EL/EM CPU Unit. Note CX-Programmer version 9.3 or lower cannot be used to confirm unit versions for CP1L-EL/EM CPU Units. ■ Confirmation Procedure Procedure When the Device Type and CPU Type Are Known 1,2,3 . 1. Set the Device Type Field in the Change PLC Dialog Box to CP1L-E. Lot No. Product nameplate CP-series CPU Unit Unit version (Example for Unit version 1.0) CP1L-EM40DR-D CPU UNIT Lot No. 01312M Ver.1.0 OMRON Corporation MADE IN CHINA 00 NC 02 04 06 08 10 00 02 04 06 08 10 01 COM 03 05 07 09 11 01 03 05 07 09 11 00 01 02 03 04 06 00 01 03 04 06 COM 02 COM 05 07 COM COM(V+) 05 07 MAC Address: 01234567890A SYSMAC CP1L BKUP ERR/ALM LNK/ACT POWER RUN INH 2 ANALOG INPUT V1 + V2 + COM EXP 1 vii 2. Click the Settings Button by the Device Type Field and, when the Device Type Settings Dialog Box is displayed, set the CPU Type Field to EL or EM. 3. Go online and select PLC - Edit - Information. (Refer to 5-1 Connecting the CX-Programmer) The PLC Information Dialog Box will be displayed. viii Use the above display to confirm the unit version of the CPU Unit. Procedure When the Device Type and CPU Type Are Not Known This procedure is possible only when connected directly to the CPU Unit with a serial connection. If you don't know the device type and CPU type that are connected directly to the CPU Unit on a serial line, select PLC - Auto Online to go online, and then select PLC - Edit - Information from the menus. The PLC Information Dialog Box will be displayed and can be used to confirm the unit version of the CPU Unit. ix Using the Unit Version Labels The following unit version labels are provided with the CPU Unit. These labels can be attached to the front of previous CPU Units to differenti- ate between CPU Units of different unit versions. Ver. 1.0 Ver. 1.0 Ver. Ver. These Labels can be used to manage differences in the available functions among the Units. Place the appropriate label on the front of the Unit to show what Unit version is actually being used. x xi TABLE OF CONTENTS PRECAUTIONS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . xxiii 1 Intended Audience. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . xxiv 2 General Precautions. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . xxiv 3 Safety Precautions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . xxiv 4 Operating Environment Precautions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . xxvi 5 Application Precautions. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . xxvii 6 Conformance to EC Directives . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . xxx 7 Software Licenses and Copyrights . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . xxxiii SECTION 1 Features and System Configuration . . . . . . . . . . . . . . . . . . . 1 1-1 Features and Main Functions. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 1-2 System Configuration . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 1-3 Function Charts . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16 1-4 Function Blocks. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 17 SECTION 2 Nomenclature and Specifications . . . . . . . . . . . . . . . . . . . . . 19 2-1 Part Names and Functions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .20 2-2 Specifications. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25 2-3 CP1L-EL/EM CPU Unit Operation. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 44 2-4 CPU Unit Operation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 51 2-5 CPU Unit Operating Modes. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 55 2-6 Power OFF Operation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 58 2-7 Computing the Cycle Time . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 60 SECTION 3 Installation and Wiring . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 71 3-1 Fail-safe Circuits . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 72 3-2 Installation Precautions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 73 3-3 Mounting . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 75 3-4 Wiring CP1L-EL/EM CPU Units . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 81 3-5 Wiring CPU Unit I/O. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 87 3-6 CP-series Expansion I/O Unit Wiring . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 94 SECTION 4 I/O Memory Allocation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 101 4-1 Overview of I/O Memory Area . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 102 4-2 I/O Area and I/O Allocations. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .108 4-3 1:1 Link Area. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 114 4-4 Serial PLC Link Area . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 115 4-5 Internal Work Area . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 115
