4 Modbus addresses
Data type,
type of access
The following tables contain specifications of all process and device data
including their addresses, data type and type of access.
Meaning:
R/O
Read only access
W/O
Write only access
R/W
Read/write access
INT
Integer (8 or 16 bit)
Bit x
Bit No. x (bit 0 is always the bit with the lowest value)
LONG
Long integer (4 byte)
FLOAT
Float value (4 bytes) as per IEEE 754
TEXT4
Text 4 characters
4.1 Process data
A
Write operations to R/W parameters result in them being saved to
the EEPROM. These memory modules only have a limited number
of write cycles (approx. 100000). For this reason, this function can
be switched off in the case of frequent programming. The
parameter values are then only saved in the volatile memory (RAM)
and will be lost after a supply failure.
v
Setup program (undocumented parameters -> Bit parameters
-> Set parameter 2)
