About this manual This manual explains operations of the High-Density and Multiplex Units, peripheral devices for Om RON C-series Programmable Controllers that are used to interface the Pc to input devices and l/o sources Section 1 provides an introduction to the switches and indicators found on the High-Density and mul tiplex Units and describes possible system configurations Section 2 describes the functions and operations of the Units Section 3 explains the relation between the scan time and lyo refresh Section 4 shows an application example Appendices, a Glossary, and an Index are also included AWARNING Failure to read and understand the information provided in this manual may result in personal injury or death, damage to the product, or product failure. Please read each section in its entirety and be sure you understand the intormation provided in the section and related sections before attempting any of the procedures or operations given SECTION 1 Hardware Description The C200H High-Density and Multiplex t/o Units are Special I/O Units. This section describes the physical layout, sys- tem connections. and bit allocations of the units. 1-1 Introduction 1-2 Nomenclature..,,,,,,,,,,,,,,,,, 1-3 Connector Assembly......... 1-4 System Connections 1-4-1 Bit allocations 246778 1-4-2 Unit Connections Introduction Section 1-1 ntroduction The term multiplex means to use one path for several signals. a multiplexer is an lyo device that routes data from several sources to a common path and then to several destinations. This is the main function of the C200H High Density and Multiplex IyO Units. The Units also can receive very short input signal. A special high-speed buffer is used to hold short input signals until the next refresh cycle. this function is called a quick-response input Seven versions of the C200H exist and are chosen depending on the number of lo points needed and the rated supply voltage C200H Units Unit Model no Input Output Supply Description Voltage TL Input Unit C200H-ID501 32 pts.--5VDC32-point input 24-VDC Input c200H|D21532pts 24 VDc 8 points available as quick-response inputs Unit TL Output Unit C200H-OD501 32 pts. 5 VDc Selectable between 32-point output or dynamic output Transistor C200HOD215- 32 pts. 24 VDC Output Unit TTLIO Unit C200H-MD501 16 pts. 16 pts.5 VDC Selectable between 16-point I/O or dynamic input 12-VDC C200H-MD115 16 pts. 16 pts. 12 VDC mode Input/Transistor 8 points available as quick-response inputs Output 24-VDC C200H-MD215 16 pts. 16 pts.24 VDC Input/Transistor Output System Configuration The C200H Units operate as Special I/O Units Up to 10 C200H special IO Units, including PC Link Units, can be mounted on the CPU, IyO Expansion or Remote l/o Slave Racks The following table lists all of the available peripheral Units in the C-series Unit Model no High-Density and Multiplex IyO Units C200H-ID501 C200H-D215 C200H-OD501 C20oH0D215 C200HMD501 C200H-MD115 C200H-MD215 High-Speed counter C200H-CTo01-V1 C200H-CT002 AD Unit C200H-ADO01 D/A Unit C200H-DAOO1 Position Control Unit C200H-NC111 C200H-NC112 C200H-NC211 Temperature Sensor Unit C200H-TS001 C200H-TS002 C200H-TS101 C200H-TS102 ID Sensor Unit C200H-IDS01 Voice unit C200H-OV001 Introduction Section 1-1 Unit Model no ASCll Unit C200H-ASC02 PC Link Uni C200H-K401 Mounting to a Remote I o The maximum number of special lyo Units that can be mounted to a Remote Slave rack Slave Rack differs depending on the group(A, B, C, or D, as shown in the following table) to which they belong An maximum of ten Units can be mounted to one remote lyo Slave Rack The nc211 Position Control Unit is counted as two Units and. if a pc link Unit is used. it is counted as one Unit This information in this table applies when no other Special I/o Units are mounted to other Racks(PC or Expansion I/O Racks)and the Units in this table are mounted only to a Remote Io Slave Rack A B D High-Speed Counter High-Density and Multiplex Temperature Sensor Unit Position Control Unit Position control unit yO Unit (NC211) (NC111/NC112), ASCII Unit Analog l/O Unit, ID Sensor 4 Units max 8 Units max 6 Units max 2 Units max When combining Units from groups A, B, C, and D, use the following formula 3A+B+2C+6Ds12 A+B+C+D≤8 Nomenclature Section 1-2 1-2 Nomenclature The front panel has the 2 l/0 connectors(CN1, CN2), the unit (machine) number selection dial, and the active bit display. The rear panel has the PC Backplane connector and the word selection DIP switch The following diagram shows the front panel D215 RUN 0123456 When the Unit is running, RUN is lit 89101112131415 01234567 DIsplay LEDs are lit when the corresponding lo points are ON (static mode only 89101112131415 MACHINE No Unit(machine) number selection dial CN1 CN2 O connectors Note The display LEDs are lit during normal operating periods. When an error oc curs, they are unlit. When rUN is unlit, I/O refresh is not performed. When the dynamic l/0 is used, the display operates differently from the static mode Refer to 2-2 Dynamic Input and 2-3 Dynamic Output for details. When setting the Unit numbers take care not to use the same number for more than one unit on the same PC. an error will result if the same number is used
