Error Codes Display Function The LCD display on the Main Unit can not only indicate the
I/O status, but also perform error code display function (01~99
or E0~E9). This is a very useful function which allows easy
maintenance of a machine.
External Interrupt and High Speed Counter Functions The Main Unit contains 6 rapid input points [X0~X5) which
can be
used as the external interrupt or high speed counter input
terminals.
It can be connected with maximally 6 single-phase high-speed
counter input signals or 2 AB-phase rotations encoders.
Handy System Functions
→With a built-in Flash program memory, no back-up battery required. →Main programs, component annotations and program annotations can completely be
loaded to the PLC, which allows easy system maintenance. →Plenty instructions (including In-Line Comparisons) has made program writing easy. →The password protection function can prevent any unauthorized program upload, thus the
intellectual property right can be protected. →With a Real Time Clock card installed, timer and related applications will set off
automatically. →AC power input from AC 85V to 264V (AC power unit only).
Flexible Modular Structure With Multitudinous Models and Modules →The
Main Unit comes in 10 to 60 I/O points for various needs.
(provide 10, 14, 20, 24, 28. 32, 40 and 6O points) →A
selection of I/O extension modules in the range of 4X/4Y to
16X/16Y is available to meet
different requirements.

Various Communication Functions →The
Main Unit has a built-in RS-232 (CP1) communication port which
enables data to be
transferred between the PLC and the computer, HMI or SCADA.
Also, through this port,
program editing and data monitoring can be performed remotely
via MODEMs. →Multiplex
communication cards and expansion modules provide RS-232 and
RS-485
interfaces. A system can be expanded up to 3
communications ports (CP1~CP3). →Through
the Computer Link (protocol for VH, VB and M series) or MODBUS
slave
communication protocol, VH series PLC can be connected
with a computer, HMI or SCADA to form a local area monitoring
network. →The
VH series PLC has the MODBUS (master) communication function
which can be used
to connect to any MODBUS enabled peripherals to access data. →The
VH series PLC has the Non-Protocol communication function which
is applied when
there are no any specific communication protocol can be
performed. All the
communication processes are customized and completed by PLC's
user program. This
function is useful when connecting with various equipment
which cannot be communicated
using the MODBUS communication protocol.
