WSK INTELLIGENT TEMPERATURE AND HUMIDITY CONTROLLER
WSK INTELLIGENT TEMPERATURE AND HUMIDITY CONTROLLER
At this time the parameter can be modified by pressing the shift key “SET”,
Increasing key “ ”, reducing key “ ”. Click the confirm button “ ”
to save the data after modification. If you need continue to modify other
parameter, press the increasing key “ ” and reducing key “ ” selection
need to modify the pattern. In setting mode, if modified, and then click the
confirm button “ ” to return to normal state
Attention
This controller has automatic returning function. When the operator set parameter modification
operation
and forget to return to the main display mode, the instrument after 30 seconds
automatically return to the main display mode
etc
.
Before using the controller or modifying the parameter of the controller, please read the
following instructions carefully.
Mode content and parameter list
Communication agreement
The physical layer
communication interface, the asynchronous half-duplex mode
Communications speed can be set to 1200-9600 BPS, the factory default 2400 BPS
Byte transfer formats: one start bit, 8 data bits, parity (N81, E81, 081) optional,
factory default E81
Digital communication protocol:
The controller provides asynchronous duplex RS485 serial communication interface and
adopts the MODBUS-RTU protocol, all kinds of data information can be transmitted on the
communications lines. One route can connect to 32 network controller at the same time,
each controller can be set different mailing Address (the Address No.), different series
controller communication terminal number is different, the communication connection is
shielded twisted-pair cable should be used with copper net, wire diameter is not less than
0.55 mm. Wiring should keep communication lines from high voltage cable, or other strong
electric field environment, T type is recommended for the network connection
(see figure 1), but does not recommend a star or other contact way

communication protocol:
The MODBUS-RTU communication protocol uses the master-slave communication
response mode connections on a communication line. First of all, the main computer
of the signal only address addressing to a terminal equipment (machine), and then,
the response signal from the terminal to transmit to host in the opposite direction, i.e.,
in a single communication line signal transmission instead of two direction all
communication data flow (half duplex working mode). MODBUS protocol is
only allowed on the host (PC, PLC, etc.) and the communication between the
terminal equipment (see chart 2), and does not allow independent data exchange
between terminal equipment, so that each terminal equipment not occupy the
communication line when they are initialized again, but only in response to the
native query signal
