Functions
and Characteristics |
|
 |
Staple structure with convenient extending
and high reliability; |
|
Double network redundant configuration
with redundant, it has good safety and strong anti-interference; |
|
Double hot-hosts for mutual redundant,
it has high stability and reliability; |
|
Control mode is the integration of program
control, remote control and local control; |
|
When start/stop equipment manually,
the host can supply operation guide; |
|
All the programmed logic, interlock
protection, control and PID adjusting can be done by PLC without
hardware; |
|
Directly display and print the measuring
parameters of process chart, control mode, equipment status,
fault status and report on CRT of the host; |
|
If any parameter overlimit, controlled object
fault, status changing or control system fault happens, it will
display in different color on CRT and make acoustic alarm. |
