4. NETWORK VARIABLE CHARTS
CAUTION
This system adopts the manner of shared network variable to manage
A/C system, which cannot access the appointed A/C within central
A/C system, until the corresponding network variable is modified
to the one that is intended to access. This device consists of two
transceivers (the following called Main controller and Auxiliary
controller for short); Main controller is responsible for querying
and setting of 32 sets air conditioners with addresses of 0~31 and
unified setting all the air conditioners (64 sets at most), and Auxiliary
controller is responsible for querying and setting of 32 sets air
conditioners with addresses of 32~63.
4.1. NETWORK VARIABLES OF MAIN CONTROLLER
There are 4 network variables of main controller, as follows:
NetWork Variables of setting Main controller
NO. Meaning Name
1 Baud rate nciUARTBaud
2 Waiting time nciWaitRespTime
3 period nciWaitTime
Network variables assigned to air conditioners (address 0~31)
Each air conditioner is assigned 3 input network variables(used for
setting) and 4 output network variables (used for query). As the
following figure:

SNVT_count 0: 1200bps Use for setting the baud rate of Rs
1: 2400bps 485 port(The fixed value is 2)
2:4800bps
Initial value=2
SNVT_count Initial value= When waiting the response time,
100ms give a WaitRespTimer value for the
timer while initialisation and when
the timer is time-out that means no
data recieved. (Suggest the setting
value should not less than 100ms)
SNVT_count Initial value= Adjust
300ms and affect the network variable
