Register No. Function Description
R4155 Port 1 & Port 2 without station number
checking for FATEK's external
communication protocol
y Low Byte of R4155:
=1, Port 1 without station number
checking for FATEK's external
communication protocol
(communicating with MMI/SCADA)
=Others,Port 1 checks station number, it allows
multi-drop network for data acquisition
y High Byte of R4155:
=1, Port 2 without station number
checking for FATEK's external
communication protocol
(communicating with MMI/SCADA)
=Others,Port 2 checks station number, it allows
multi-drop network for data acquisition
R4156
Port 3 & Port 4 without station number
checking for FATEK's external
communication protocol
y Low Byte of R4156:
=1, Port 3 without station number
checking for FATEK's external
communication protocol
(communicating with MMI/SCADA)
=Others,Port 3 checks station number, it allows
multi-drop network for data acquisition
y High Byte of R4156:
=1, Port 4 without station number
checking for FATEK's external
communication protocol
(communicating with MMI/SCADA)
=Others,Port 4 checks station number, it allows
multi-drop network for data acquisition

Register
(Not for High Speed CPU Link)
Set Baud Rate, Data bit…of Port 2
R4159
Transmission Delay & Receive
Time-out interval time Setting,
while Port 2 being used as the master of
FUN151 or FUN150
Low Byte：Port 2 Receive Time-out interval time
(Unit in 10mS)
High Byte：Port 2 Transmission Delay
(Unit in 10mS)
R4160 Port2 RX/TX time out setting for High
Speed CPU Link
High Byte of R4160 :
=56H, User setting mode if the system default works not
well, Low Byte of R4160 is used for this setting (Not
suggest)
=Others, system will give the default value according to
the setting of R4161
