2. MODBUS map
Data type for FLXA402 MODBUS map
Data type Denition
oat oating point (4byte)
IEEE754
NaN: 0x7FFFFFFF
int16 16 bit signed integer
uint16 16 bit unsigned integer
uint32 32 bit unsigned integer
ASCII character set (using one byte per
character), multiple registration possible
bit elds data assigning information on bit
Access (load/import) to multiple registration such as oat, uint32, ASCII etc. must be
implemented at once.
Latest revision does not support script, or arithmetic by multiple sensors.
