cpu modules is the heart of the PLC system. It executes the control instructions of the control logic program. It also communicates with other devices, which can include I/O Devices, Programming Devices, computers, Networks, and even other plcs and also performs diagnostics tasks.

Full servo warp knitting machine mechanical structure and working principle plc cpu modules control
The traditional textile industry processes , including fibers,
weaving, finishing and garment four parts. Weaving process , including
woven , knitted , woven and non-woven . Divided into warp knitting Nanda digital input module and
weft . After all the work on the needle with a group or several groups
of yarns arranged in parallel , in the warp feeding machine , but formed
into a circle knit , this method is called warp knitted fabric formed
by weaving called matter . Our warp knitting industry after decades of
development , constant restructuring, especially high in recent years,
companies in emerging regions warp starting point , reasonable structure
, significant Nanda ethernet module plc economies
of scale , into scientific research universities and research
institutes , as well as research combined to make our warp knitting
industry has been developing rapidly , is becoming the center of world
warp industry. Traditional warp knitting machines , mostly chain-type
warp knitting machine , because of its mechanical structure of the
spindle drive , no import electric drive , resulting in its following
disadvantages: woven flowers slow and inefficient ; chain complex
mechanism , each replacement of a Nanda micro smart plc flower
, you need to spend more time , and each pattern corresponds to a chain
block , this time to replace the long pattern , high cost. Resulting in
the production of small batch orders lost meaning ; due to the
complexity of the organization , resulting in a complex pattern can not
be produced on a chain block machine . Only produce relatively simple
fabric flower , can not meet the increasing demands , the current full
servo warp knitting machine has gradually been applied in the textile .
Now all servo on warp knitting machine production , efficiency , pattern
diversity, quality of products have a good advantage , and therefore
will become the mainstream in the future jacquard weaving .
