Wizit Dongdo Calorimeter communication driver read schedule

Read schedule setting parameters are as follows:

1) Station Address – 0 ~ 255 station Address.

2) Read command – command = fixed to CURR.

3) Read start address – don't care.

4) Save start address for Communication Server – Saving start address of Communication Server.

5) Read Size – fixed to 1. ( refer to <table 1> )
