Register No. Function Description
R4046 Power up initialization mode selection of data
registers that has been written into ROM
Pack.
=5530H: Don’t initialize the addressed data registers
been written into ROM Pack while power up
=Others : initialize the addressed data registers been
written into ROM Pack while power up
R4047 Communication protocol setting for Port1～
Port4
Set the FATEK or Modbus RTU communication
protocol
R4048
Transmission Delay & Receive
Time-out interval time Setting,
while Port 4 being used as the master of
FUN151 or FUN150
Low Byte：Port 4 Receive Time-out interval time (Unit
in 10mS)
High Byte：Port 4 Transmission Delay
(Unit in 10mS)
R4049 CPU Status Indication =A55AH, Force CPU RUN
=0, Normal Stop
=1, Function(s) existed that CPU does not support
=2, PLC ID not matched with Program ID
=3, Ladder checksum error
=4, System STACK error
=5, Watch-Dog error
=6, Immediate I/O over the CPU limitation
=7, Syntax not OK
=8, Qty of expansion I/O modules exceeds
=9, Qty of expansion I/O points exceeds
=10, CRC error of system FLASH ROM
R4050 Port 0 Communication Parameters Register Set Baud Rate of Port 0
R4051 Reserved
R4052 Indicator while writing ROM Pack
R4053 Reserved
R4054 Define the master station number
of the High-Speed CPU Link network
(FUN151 Mode 3)
If the master station number is 1,it can ignore this
register.
To set the master station number other than 1 should:
Low Byte : Station number
High Byte: 55H
R4055 PLC station number
y If high byte is not equal 55H, R4055 will show the
station number of this PLC
y If want to set PLC station number then R4055
should set to:
Low Byte : Station number
High Byte: 55H
R4056
High Byte :Reserved
Low Byte: High speed pulse output frequency
dynamic control
Low Byte: =5AH, can dynamically change the output
frequency of High Speed Pulse Output
R4057 Power off counter The value will be increased by 1 while power up
R4058 Error station number while Port 2 in High
Speed CPU Link
Used by FUN151 Mode 3 of Port 2
