Characteristics of the TME400 Modbus
- Data types (float, text ...) can only be read or written completely
menu16 : 1 Register
int16 : 1 Register
uint16 : 1 Register
int32 : 2 Register
uint32 : 2 Register
float : 2 Register
string8 : 4 Register
string12 : 6 Register
- A maximum of 125 registers can be read or written (in one command).
- Text fields must have at least one terminating zero (0x00).
- Writing of certain parameters causes internal initialization of the hardware and/or:
- Deletion of intermediate results (pulse output, meter calculation, etc.).
- Therefore, the parameters should only be overwritten as necessary
(e.g. meter factor)
- Meter statuses are delivered as a uint32 value (without decimal)
