MicroVission Communication Table
Scope: MicroVission Programs – version 1.1
NOTES:
• All ENUM variables are of INT (Integer) type
• All F-INT data types represent floating point values
as INT types multiplied by 10
• All Pressures are in Psig
• All Temperatures are in Fahrenheit
• Modbus TCP addressing is PLC-style (Base 1) ad-
dressing
• On Error, Modbus TCP server only returns an error
code of "Illegal Data Address"

• All registers returned (INT and F-INT) are 2 bytes
long
• For Ethernet/IP, use INT data type and PLC-5 Word
Range Read/Write MSG instructions
• Remote commands cannot be issued if the panel is
in the "Remote Lock" mode
• Polling rates should not be less than 5 secs
• Writes to the MicroVission should only occur when
a value needs to be changed
• Lower Range and Higher Range values mentioned
are default values of MicroVission setpoints
• Users can modify Lower Range & Higher Range
values from MicroVission Panel and accordingly
maintain their own table
