There are 4 ways to connect through RS-422A/485 cable.This explanation focuses on connections to OMRON PCs, although anyRS-422A device can be connected using the memory link method.• Method 1This is a 1:1 connection between the PT’s RS-232C port and host’s RS-422Aterminals (using RS-422A cable) through a Link Adapter. The communicationscable can be extended up to 500 m long with this method.PTLinkAdapterHostRS-422A cable(500 m max.)RS-232C cable(2 m max., notrequired with theNS-AL002.)• Method 2This is a 1:1 connection between the PT’s RS-232C port and host’s RS-485terminals (using RS-485 cable) through a Link Adapter.

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 LinkMethod (page 80) or Using the High-speed 1:N NT Link Method (page 83).5-1-1 Host Types and SettingsThis section lists the hosts that have RS-422A ports that can be connected to aPT and describes the settings required at the host.When Using the Host Link MethodCompatible Host UnitsSome models and series of OMRON PCs have the RS-422A type Host Linkfunction built in.
With a CS series, CJ series, and CQM1H Board or Unit, andCQM1H, the Host Link method can be used by installing a Serial Communications Board. In addition, some C200HX/HG/HE(-Z)E devices have an integralCPU Unit that can be connected in the Host Link method by installing a SerialCommunications Board.With the CPM2A and CPM2C, an RS-422A type of 1:1 NT Link can be connected through a CPM1-CIF11 RS-422A Adapter.Check the model and series of the PC and the type of the installed Board or Unitbefore making a connection.69SectionConnecting to the Host’s RS-422A/485 Port5-1The following table lists the Units that are equipped with an RS-422A Host Linkfunction compatible with the NT21.Units with Built-in Host Link FunctionPC SeriesHost Link Unit /Serial CommunicationsBoardCPU Units Connectable withHost Link Units or Expansion Serial Communications BoardCPU UnitConnectabletoCS SeriesCS1W-SCB41-E---CS1G-CPU42/43/44/45-EV1CS1H-CPU63/64/65/66/67-EV1CS1G-CPU42H/43H/44H/45HCS1H-CPU63H/64H/65H/66H/67HCJ SeriesCJ1W-SCU41---CJ1G-CPU44/45CJ1G---C200HS-CPU01/03/21/23/31/33-EC200HS-CPU01/21-ECC200HE-CPU11/32/42-EC200HE-CPU11/32/42-ZEC200HG-CPU33/43/53/63-EC200HG-CPU33/43/53/63-ZEC200HX-CPU34/44/54/64-EC200HX-CPU34/44/54/64/65/85-ZEC200HSC200HEC200HE-ZEC200HGC200HG-ZEC200HXC200HX-ZEC200HE-CPU32/42-EC200HE-CPU32/42-ZEC200HEC200HE-ZEC200HG-CPU33/43/53/63-EC200HG-CPU33/43/53/63-ZEC200HGC200HG-ZEC200HX-CPU34/44/54/64-EC200HX-CPU34/44/54/64/65/85-ZEC200HXC200HX-ZE---CPM1C200H-LK202-V1C200HW-COM03/06-EV1---C SeriesCPM1-10/20/30CDR-j+CPM1-CIF11---CPM1A-10/20/30/40CDj-j+CPM1-CIF11CS1GCS1HCS1G-HCS1H-H---CPM2A-30/40/60CDj-j+CPM1-CIF11(Peripheral port connection)---CPM2A---CPM2C-10/20jjjjjj-j (*1)---CPM2CCQM1H-SCB41---CQM1H-CPU51/61CQM1HCVM1 Series (*2)CV500-LK201CVM1-CPU01-EV2CVM1-CPU11-EV2CVM1-CPU21-EV2CVM1-CPU01-EV2CVM1-CPU11-EV2CVM1-CPU21-EV2CVM1SRM1---SRM1-C02-V1+CPM1-CIF11---SRM1*1: Use a CPM2C-CN111 or CS1W-CN114/118 Connecting Cable, CPM1-CIF01 RS-232C Adapter, or CPM1-CIF11RS-422A Adapter to connect.*2: CPU Units of CVM1/CV-series PCs without the suffix -EVj cannot be connected.The Host Link method cannot be used when an NT21 is connected usingRS-485.
