When the automatic transmission is operating, it is displayed in Japanese.• The continuous buzzer sounds.• The RUN Indicator flashes.If a protect setting error occurs when executing manual transmission, it is possible to return to the Memory Unit manual transmission screen by pressing theOK touch switch, but in the case of other errors, the status described above remains in effect until the NT21 power is turned OFF or reset.When an error occurs, take remedial action by referring to the table below.Probable CauseRemedial ActionMode setting errorErrorDIP Switch pins SW1-1to SW1-3 are all OFF, ormore than one is ON.Turn the NT21 power OFF, set theMemory Unit DIP switchescorrectly, then turn the NT21power back ON.Protect setting error(automatictransmission)Writing to the data writedestination has beenprohibited by the settingof SW2-1 or SW2-2.Turn the NT21 power OFF, set theMemory Unit DIP switchescorrectly, then turn the NT21power back ON.Protect setting error(manualtransmission)Writing to the data writedestination has beenprohibited by the settingof SW2-1 or SW2-2.Perform either of the followingprocedures.S Press the OK touch switch to return to the Memory Unit manualtransmission screen, make thecorrect settings, then try again.S Turn the NT21 power OFF, correct the DIP switches settings ofthe Memory Unit, then turn thepower back ON.Flash memory errorAn error occurred duringinitialization of the NT21or Memory Unit flashmemory, or during writeprocessing.Turn the NT21 power OFF, thenback ON.
If the error recurs, theflash memory at the writedestination may be faulty. In thiscase, replace the Unit.Verify errorAn error occurred duringverification processing atthe flash memory of theNT21 or the MemoryUnit.Turn the NT21 power OFF, thenback ON. If the error recurs, theflash memory at the writedestination may be faulty. In thiscase, replace the Unit.Transmitting dataerror(The automatictransmission only)An attempt is made totransmit data other thana system program or thesystem program of adifferent PT model intothe NT21 as the systemprogram.An attempt is made towrite a system programinto the NT21 as screendata.Perform either of the followingprocedures.S Turn the NT21 power OFF, correct the DIP switch settings of theMemory Unit, and then turn thepower back ON.S Turn the NT21 power OFF, setthe DIP switch settings to themanual transmission, and thencheck the data inside theMemory Unit.37SECTION 4Connecting to the Host from the RS-232C PortThis section describes how to connect the host directly to the NT21’s RS-232C port.4-1Connecting to the RS-232C Port at the Host .

Depending on the host to which the connection is to be made, it may be possible to use OMRON cables with connectors.NT21HostRS-232C cable (max. 15 m)Reference: The CS/CJ-series CPU Unit cannot be connected with the 1:1 connection NT linkmethod.
Use the 1:N connection NT link method instead of making the 1:1 connection. For details, refer to Using the 1:N NT Link (page 55) or Using the Highspeed 1:N NT Link (page 60).4-1-1 Host Types and SettingsThe types of host that can be connected to a PT by using the RS-232C ports ofboth devices, and the settings to be made at the host, are described here.Using the Host Link MethodCompatible Hosts40Some models and series of OMRON PCs have the Host Link function built in.In the CS-series (including the CS1-H PCs), CJ-series, and CQM1H PCs, theHost Link method can be used by installing a Serial Communications Board orUnit.
In addition, some C200HX/HG/HE(-Z)E have an integral CPU Unit that canbe connected in the Host Link method by installing a Communication Board.Check the model and series of the PC, the type of installed Serial Communications Board, Serial Communications Unit, or Host Link Unit before making a connection.SectionConnecting to the RS-232C Port at the Host4-1The hosts that can be connected to the NT21 by the Host Link method using theRS-232C ports of both Units are indicated in the table below.PC SeriesUnits with Built-in Host LinkFunctionCPU Units Connectable with HostLink Units or Expansion Communication BoardHost Link Unit/Communication BoardConnectabletoCS 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/45HCS1H-CPU63H/64H/65H/66H/67HCS1W-SCU21CS1W-SCB21CS1W-SCB41CS1GCS1HCS1G-HCS1H-HCJ SeriesCJ1G-CPU44/45CJ1G-CPU44/45CJ1W-SCU41CJ1G---C200HS-CPU01/03/21/23/31/33-EC200HE-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-ZEC200H-LK201-EV1C200HSC200HEC200HE-ZC200HGC200HG-ZC200HXC200HX-ZC200HS-CPU21/23/31/33-E------C200HSC200HE-CPU42-EC20HE-CPU42-ZEC200HG-CPU43/63-EC200HG-CPU43/63-ZEC200HX-CPU44/64-EC200HX-CPU44/64/65/85-ZECPM1-10/20/30CDR-j+CPM1-CIF01CPM1A-10/20/30/40CDj-j+CPM1-CIF01CPM2A-30/40/60CDjj-j+CPM1-CIF01(Peripheral port connection)CPM2C-10/20jjjjjj-j(*1)CQM1-CPU21-ECQM1-CPU41/42/43/44-EV1CQM1H-CPU11/21/51/61 (*2)C200HE-CPU32/42-EC200HE-CPU32/42-ZEC200HG-CPU33/43/53/63-EC200HG-CPU33/43/53/63-ZEC200HX-CPU34/44/54/64-EC200HX-CPU34/44/54/64/65/85-ZEC200HEC200HE-ZC200HGC200HW-COM02/04/05/06EV1 C200HG-Z05/06-EV1C200HXC200HX-Z------------------CPM2A------CPM2C------CQM1CQM1H-CPU51/61CQM1H-SCB41CQM1HCVM1 Series (*3)CVM1-CPU01-EV2CVM1-CPU11-EV2CVM1-CPU21-EV2CVM1-CPU01-EV2CVM1-CPU11-EV2CVM1-CPU21-EV2CV500-LK201CVM1CompoBus/S Master UnitSRM1-C02-V1------SRM1C SeriesCPM1*1: Use a CPM2C-CN111 or CS1W-CN114/118 Connecting Cable, CPM1-CIF01 RS-232C Adapter, or CPM1-CIF11RS-422A Adapter to connect.*2: The CQM1H-CPU11 does not have a built-in RS-232C port, so connect to the PT at the peripheral port with aCS1W-CN118 Connecting Cable.*3: CPU Units of CVM1/CV-series PCs without the suffix -EVj cannot be connected.Settings at the HostWhen using the Host Link method, the settings shown below must be made atthe host (depending on the Unit, some of these settings may not be necessary,or settings not shown here may be necessary).ItemSwitch SettingI/O portRS-232CBaud rateSet the same baud rate as for the NT21.

Either of these ports can be used for connection to anNT21 by the RS-232C method. However, since the connectors at these ports areof different types, a cable that matches the connector must be prepared.• Communication port 1Communication port 1 is a 25-pin connector for RS-232C use only.• Communication port 2Communication port 2 is a 9-pin connector that allows selection of theRS-232C or RS-422A method.
