HIMOS HI575 and
HI576 operator interfaces provide
man-machine interface for PLCs / Inverters. The user
can implement PLC logic using standard ladder logic
programming.
The HIMOS unit has four high speed
counters (25 kHz each), hundreds of timers and counters,
thousands of internal coils, retentive and non retentive
memory registers and PID functionality.
Can communicate with PLCs using its serial communication
ports to fetch the information requested by the operator.
This information can be either the value of a PLC register
or the status of an I/O, or whatever other PLC parameter
available.
This information can be displayed on
HI575/HI576 screen, and if required, the HMI can also modify the
value of these PLC registers or parameters.
It is also possible to provide the HMI with I/O, either
analogue or digital, thanks to remote I/O modules available
for the
HIMOS Series.
HI575 has 2 serial communication ports, and
HI576 has
also 2 serial communication ports plus a third Ethernet
port. Direct connection to Modbus RTU protocol and
other opened protocols and to most of PLCs. They can
communicate with two different PLCs simultaneously.
PLC task can be executed on power up, during continuous
scanning, when a specific screen is showing, or
when a specific wizard event occurs. Allows local or
global assignation of keys to macros for key processes.
