Circutor CVM-B100 - 6.3.7.- UNIT CONFIGURATION VARIABLES

6.3.7.- UNIT CONFIGURATION VARIABLES
The following functions are implemented for these variables:
Function 0x04: reading registers.
Function 0x10: Writing multiple registers.
Note: The programming values must be written in hexadecimal.
It is necessary to change the screen when a setup change is made for communi-
cations in order for the changes take effect in the display.
6.3.7.1.- Date and time
These parameters occupy 1 register each.
Table 30:Modbus memory map: Conguration variables (Date and Time).

Month 283D 1 to 12 -
Day 283E 1 to 31 -
Time 283F 0 to 23 -
Minutes 2840 0 to 59 -
