MicroVission Communication Table
Scope : MicroVission Programs – version 1.0 .
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) addressing
• 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
