You can reset to factory settings by using the menu option:
Network-> IP Config. -> Factory-> RST Log on
After you reset the logon, the username and password will be
set back to the default "admin".
RIEVTECH On-line
RIEVTECH On-line Interface
You can monitor and operate the LCD panel remotely.
The CPU only can only get a momentary trigger from the virtual
keys, it cannot get a continuous signal, that means if you press
the OK key for 3 seconds, the CPU does not know how long
it was pressed for, it only knows that is was pressed.
So, if you want to realize the pressing of the OK key for 3
seconds to change the parameters in a text message block
on the hardware, you need press the "set" key on the virtual
panel instead.
Press "Set" = Press OK key for 3 seconds then the parameters
in the text message block can be modified in the usual way
using the cursor keys.

How to Establish the Communication between new
Ethernet CPUs
We can make an Ethernet connection based on a TCP or UDP
connection. This is achieved using the following method.
Configure and Create a Connection (TCP or UDP)
Each CPU has 8 TCP connections, and can work both as a
TCP Server and a TCP Client, so a lot of CPUs can be
connected in a network.
Programming and Data Transmission
We need to use the "Modbus Read and Write" function block
in the Master CPU. The TCP server or the TCP client CPU can
work as master and/or slave depending on what you need to
achieve.
Example 1: One Master CPU (TCP Server) connected to Three
Slave CPUs (TCP Clients)
The connection sketch:
Requirement:
1.If I1 of the Master CPU is ON/OFF, then the output Q1 of
Slaves 1 to 3 are ON/OFF.
2.Read the analogue input, AI2 value from the slave1 through
slave3 and store in variables AF1 to AF3 of the Master CPU
and display.
