Description
R4146
Port 1 Communication Parameters
Register
Set Baud Rate, Data bit… of Port 1
R4147
Transmission Delay & Receive
Time-out interval time Setting,
while Port 1 being used as the master of
FUN151 or FUN150
Low Byte
：
Port 1 Receive Time-out interval time
(Unit in 10mS)
High Byte
：
Port 1 Transmission Delay
(Unit in 10mS)
R4148
Message Frame Detection Time Interval .While the communication port being used as the master or
slave of Modbus RTU protocol, the system will give the
default time interval to identify each packet of receiving
message; except this, the user can set this time interval
through the high byte setting of R4148 and let M1956 be
1, to avoid the overlap of different packet of message
frame.
M1956=1, High Byte of R4148 is used to set the new
message detection time interval for Port 1
～
Port 4 (Unit
in mS)
.While the communication port being used to communicate
with the intelligent peripherals through FUN151
instruction, if the communication protocol without the end
of text to separate each packet of message frame, it
needs message detection time interval to identify the
different packet. High byte of R4148 is used for this
setting for Port 1
～
Port 4.
(Unit in mS)
R4149
Modem Interface Setting & Port0
without checking of station number for
FATEK's external communication protocol
y
High Byte of R4149:
=55H, Remote-Diagnosis/Remote-CPU-Link
by way of Port 1 through Modem
connection, it supports user
program controlled dial up function
=AAH, Remote diagnosis by way of Port 1
through Modem connection, it
supports Passive receiving & Active
dialing operation mode
=Others, without above function
y
Low Byte of R4149:
=1, Port 0 without checking of station number
for FATEK's external
communication protocol (communicating with
MMI/SCADA)
=Others, Port 0 checks station number, it allows
multi-drop network for data acquisition.
R4150
Power on I/O service delay time setting
y
PLC is ready for I/O service after this delay time while
power up. The unit is in 0.01S. The default value is 100.
R4151
Circular 1mS time base timer
y
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 resolution
R4153
R4154
High word of HSTA CV register
PV register of HSTA
The HSTA can act as 32-bit cyclic timer or fixed time
interrupt timer
