High byte of R4148 is used for thissetting for Port 1~Port 4.(Unit in mS)• High Byte of R4149:=55H, Remote-Diagnosis/Remote-CPU-Linkby way of Port 1 through Modemconnection, it supports userprogram controlled dial up function=AAH, Remote diagnosis by way of Port 1through Modem connection, itsupports Passive receiving & Activedialing operation mode=Others, without above function• Low Byte of R4149:=1, Port 0 without checking of station numberfor FATEK's externalcommunication protocol (communicating withMMI/SCADA)=Others, Port 0 checks station number, it allowsmulti-drop network for data acquisition.R4150 Power on I/O service delay time setting • PLC is ready for I/O service after this delay time whilepower up. The unit is in 0.01S. The default value is 100.R4151 Circular 1mS time base timer • The content of R4151 will be increased by 1 every 1mS.It can be used for a more precise timing application.R4152 Low word of HSTA CV register HSTA is high speed timer in 0.1 mS resolutionR4153R4154High word of HSTA CV registerPV register of HSTAThe HSTA can act as 32-bit cyclic timer or fixed timeinterrupt timer2-15
