After the settings are written, they become effective by turning the powerON, restarting the Unit, restarting the communication port, or execution of theSTUP instruction.50SectionConnecting to the RS-232C Port at the Host4-1The following table shows the words allocated in the DM Area and the settings.Allocated DM wordPort 1Port 2DM32000DM32010DM32001DM32011DM32002DM32003ValueSettings8000Host Link mode, 2 stop bits, even parity, datalength 7 bits0000Baud rate 9,600 bps.0007Baud rate 19,200 bps.DM320120000Transmit delay time 0 ms.DM320130000No CTS control Unit No.0 for Host LinkUsing the 1:1 NT LinkCompatible Host UnitsSome models and series of OMRON PCs have the 1:1 NT Link function built in.With CQM1H PCs, a Serial Communications Board can be added to provide 1:1NT Link communications.
Some C200HX/HG/HE(-Z)E CPU Units can be connected by the 1:1 NT Link by installing a Communication Board.Check the model and series of the PC against the model of CPU Unit beforemaking the connections.The hosts that can be connected to the NT21 by the 1:1 NT Link using theRS-232C ports of both Units are indicated in the table below.PC SeriesCPU Units with Built-inNT Link FunctionC200HS-CPU21-E, -ECC200HS-CPU23-EC200HS-CPU31-EC200HS-CPU33-EC SeriesCPU Units Connectablewith ExpansionCommunicationBoard(*1)Connectableto--C200HSC200HE-CPU42-(Z)EC200HE-CPU32-(Z)EC200HE-CPU42-(Z)EC200HE (-Z)EC200HG-CPU43-(Z)EC200HG-CPU63-(Z)EC200HG-CPU33-(Z)EC200HG-CPU43-(Z)EC200HG-CPU53-(Z)EC200HG-CPU63-(Z)EC200HG(-Z)EC200HX-CPU44-(Z)EC200HX-CPU64-(Z)EX200HX-CPU65-ZEC200HX-CPU85-ZEC200HX-CPU34-(Z)EC200HX-CPU44-(Z)EC200HX-CPU54-(Z)EC200HX-CPU64-(Z)EC200HX-CPU65-ZEC200HX-CPU85-ZEC200HX (-Z)ECPM1-10CDR-j (*2)CPM1-20CDR-j (*2)CPM1-30CDR-j (*2)CPM1A-10CDj-j (*2)CPM1A-20CDj-j (*2)CPM1A-30CDj-j (*2)CPM1A-40CDj-j (*2)---CPM2A-30CDjj-jCPM2A-40CDjj-jCPM2A-60CDjj-j---CPM2C-10jjjjjj-j (*3)CPM2C-20jjjjjj-j (*3)---CQM1-CPU41-EV1CQM1-CPU42-EV1CQM1-CPU43-EV1CQM1-CPU44-EV1CQM1-CPU45-EV1---CQM1H-CPU21-ECQM1H-CPU51-ECQM1H-CPU61-ECQM1H-CPU51 (*4)CQM1H-CPU61 (*4)CPM1CPM2ACPM2CCQM1CQM1H51SectionConnecting to the RS-232C Port at the HostPC SeriesCPU Units with Built-inNT Link Function(*5)CVM1-CPU01-EV2CVM1-CPU11-EV2CVM1-CPU21-EV2CompoBus/SMaster UnitSRM1-C02-V2CVM1 SeriesCPU Units Connectablewith ExpansionCommunicationBoard(*1)4-1Connectableto--CVM1---SRM1*1 One of the following Communication Boards is required:C200HW-COM02/COM04/COM05/COM06-EV1.*2 A CPM1-CIF01 adapter is required.*3 Use a CPM2C-CN111 or CS1W-CN114/118 Connecting Cable, CPM1-CIF01RS-232C Adapter, or CPM1-CIF11 RS-422A Adapter to connect.*4 A CQM1H-SCB41 Serial Communications Board is required.*5 CPU Units of CVM1/CV-series PCs without the suffix -EVj cannot beconnected.Reference: CS/CJ-series CPU Unit cannot be connected with the 1:1 connection NT linkmethod.
Use the 1:N connection NT link method (standard or high-speed)instead of making the 1:1 connection. For details, refer to Using the 1:N NT Link(page 55) or Using the High-speed 1:N NT Link (page 60).Settings at The HostThe setting methods for each Unit are as follows:Connecting to a C-series C200HS, C200HX/HG/HE(-Z)E, CPM1, CPM2A,CPM2C, CQM1, CQM1H, or SRM1PC Setup SettingsWrite the PC Setup (in the DM Area) settings directly from a Programming Device (e.g., SYSMAC Support Software) in accordance with the host model andport.Host ModelRS-232C port of C200HS,C200HX/HG/HE(-Z)E, CPM2A,CPM2C, CQM1, CQM1H, SRM1Port A of C200HX/HG/HE(-Z)E (*1)Port 1 ofCQM1H (*2)WordWriting ValueSettingDM6645DM6555Port B of C200HX/HG/HE(-Z)E (*1)DM6550CPM1DM66504000Use 1:1 NTLink*1 RS-232C port of the Communication Board*2 RS-232C port of the Serial Communications BoardFor details on operations relating to the PC Setup, refer to the manual for the PCthat is used.Connecting to a CPM2CThe CPM2C PCs do not have the same kind of port connectors found on CS/CJseries PCs.
The CPM2C’s communication port handles both RS-232C and peripheral port connections, which are divided internally. Therefore, when usingthe CPM2C, it is necessary to select RS-232C or peripheral port connections,according to the kind of cable and port (on the cable) used, as shown in the following table. Refer to the CPM2C Operation Manual for more details.52SectionConnecting to the RS-232C Port at the HostPort connecting to PT4-1PC SetupRS-232C port (D-Sub 9-pin) of CPM2C-CN111Built-in RS-232C port settingsPeripheral port of CPM2C-CN111Peripheral port settingsRS-232C port (D-Sub 9-pin) of CS1W-CN118Built-in RS-232C port settingsPeripheral port of CS1W-CN114Peripheral port settingsPeripheral portCPM2C-CN111RS-232C port(D-Sub 9-pin, female)CPM2CCS1W-CN118CPM2CRS-232C port(D-Sub 9-pin, female)CS1W-CN114CPM2CPeripheral portSetting the DIP Switches on the Front of a C200HX/HG/HE(-Z)E, CQM1,CQM1HWhen using a C200HX/HG/HE(-Z)E, CQM1, or CQM1H, the DIP switches onthe front panel must be set as shown below in order to make the settings in thePC Setup (data memory) effective.C200HX/HG/HE(-Z)ECQM1CQM1HRS-232C port communication condition settingSet pin 5 to OFF to make the settings made inPC Setup effective.Setting the Switches of a CPM2AWhen using a CPM2A, the switches on the front panel must be set as shownbelow in order to make the PC Setup settings effective.Set the Communicationsswitch to OFF (downposition).53SectionConnecting to the RS-232C Port at the Host4-1Setting the Switches of a CPM2CWhen using a CPM2C, the switches on the front panel must be set as shownbelow in order to make the PC Setup settings effective.The settings for SW1 and SW2 depend upon the usage of theperipheral port and RS-232C port.S Connecting PT to peripheral portS Connecting PT to built-in RS-232C port(A device that requires non-standard communications settingsis connected to the peripheral port.)SW1: OFFSW2: ONS Connecting PT to built-in RS-232C port(A Programming Console is connected to the peripheral port.)SW1: OFFSW2: OFFSetting the Switches on an RS-232C AdapterWhen using a CPM1-CIF01 RS-232C Adapter, set the mode switch as shown inthe following diagram.CPM1CIF01Set the mode setting switch to NT (lower position).Connecting to CVM1/CV Series (-EVj)Set the DIP switch on the front panel as follows:I/O port selection (selector switch)Set this to RS-232C.DIP switch setting (Pin 3)654321Set Pin 3 to use NT Link(ON, right side).ONOFFONWhen using a CVM1/CV-series PC, CPU Unit execution processing (executioncontrol 2) in the PC Setup must be set to Simultaneous processing.54SectionConnecting to the RS-232C Port at the Host4-1Using the 1:N NT LinkCompatible Host UnitsThe OMRON PCs that can be connected using the 1:N NT Link are the CS-series (CS1G/H or CS1G/H-H), CJ-series CJ1G, C-series C200HX/HG/HE(-Z)E,CQM1H, and SRM1 only.
With the CS/CJ-series PCs, it is possible to connect a1:N NT Link using a CS1W-SCU21 or CJ1W-SCU41 Serial CommunicationsUnit.Check the model and series of the PC as well as the model of Serial Communications Board or Unit being used before making the connections.The hosts that can be connected to the NT21 by the 1:N NT Link using theRS-232C ports of both Units are indicated in the table below.CPU Units with Built-inNT Link FunctionCPU Units Connectablewith CommunicationsBoard or Unit(*1)ConnectabletoCS SeriesCS1G-CPU42/43/44/45-EV1CS1H-CPU63/64/65/66/67-EV1CS1G-CPU42H/43H/44H/45HCS1H-CPU63H/64H/65H/66H/67HCS1G-CPU42/43/44/45-EV1CS1H-CPU63/64/65/66/67-EV1CS1G-CPU42H/43H/44H/45H(*1)CS1H-CPU63H/64H/65H/66H/67H(*1)CS1GCS1HCS1G-HCS1H-HCJ SeriesCJ1G-CPU44/45CJ1G-CPU44/45(*2)CJ1GC200HE-CPU42-(Z)EC200HE-CPU32-(Z)E(*3)C200HE-CPU42-(Z)E(*3)C200HE(-Z)EC200HG-CPU43-(Z)EC200HG-CPU63-(Z)EC200HG-CPU33-(Z)E(*3)C200HG-CPU43-(Z)E(*3)C200HG-CPU53-(Z)E(*3)C200HG-CPU63-(Z)E(*3)C200HG(-Z)EC200HX-CPU44-(Z)EC200HX-CPU64-(Z)EC200HX-CPU65-ZEC200HX-CPU85-ZEC200HX-CPU34-(Z)E(*3)C200HX-CPU44-(Z)E(*3)C200HX-CPU54-(Z)E(*3)C200HX-CPU64-(Z)E(*3)C200HX-CPU65-ZE(*3)C200HX-CPU85-ZE(*3)C200HX(-Z)E---CQM1H-CPU51(*4)CQM1H-CPU61(*4)CQM1HSRM1-C02-V2---SRM1PC SeriesC SeriesCompoBus/SMasterControl Unit*1 A CS1W-SCB21 or CS1W-SCB41 Serial Communications Board orCS1W-SCU21 Serial Communications Unit is required.*2 A CJ1W-SCU41 Serial Communications Unit is required.*3 One of the following Communication Boards is required:C200HW-COM02/COM04/COM05/COM06 (-EV1)*4 A CQM1H-SCB41 Serial Communications Board is required.Reference: The -V1 versions of CS-series PCs and CJ-series PCs support the high-speed1:N NT Link as well as the standard 1:N NT Link.
Furthermore, the high-speed1:N NT Link can be used in earlier versions of CS-series PCs by installing a newversion of Serial Communications Board or Unit.
