4 Communication settings and guide of HMI connecting with controller
NOTE：
1、When setting the parameter of ADDR, it match the PLC Station Number .
2、If connecting many devices, you should set different ADDR values.

parameters code
NOTE:
1
、When setting the parameter of ADDR, it match the PLC Station Number.
2
、If connecting many devices, you should set different ADDR values.
3
、AI-7048 has 4 loops, so it occupies 4 address, For instance, Addr=5,address 5~8 were used by this
controller, other controller can’t use address 5~8.
EXAMPLE
Take HIAL for example, look up table and then know that HIAL parameters code is 1, so HIAL for 4
channels correspond to address in HMI should be Reference0.01，Reference1.01，Reference2.01，
Reference3.01.
If station number is 2, Reference0.01 is HIAL address of channel 2(station No. 2 + main address 0),
Reference1.01 is HIAL address of channel 2(station No. 2 + main address 1), and so on.
Thereinto the setting of station number is very important, it denotes start address of the controller (viz.
instrument address in instrument parameter), and main address just denotes 4 channels. When main address
is 0, it denotes channel (station number+0)
