Variable Value Meaning
0 Number without decimal digit
1 Number with one decimal digit
2 Number with two decimal digits
3 Number with three decimal digits
4 Number with four decimal digits
5. Multiplier
Same parameters have a related variable stated as “multiplier”; this system allows to overcome
the limits of +/- 32767 counts.
Example:
The measure value 80000 is sent as:
800 at ModBus address 133 (input variable without filter)
100 at ModBus address 262 (multiplier x 100)
6. Local/Remote Status
At power up the slave will be in local mode. It is necessary to set the local/remote device status
(ModBus address 218). Returns to local mode when a write to illegal address occurs.
Local Mode:
The communication between master and slave is limited to transferring data from
slave to master without possibility of modifying any parameter from the master itself (with the
exception of the local/remote device status ). Therefore from the local keyboard, parameters can
be displayed and modified.
Remote Mode:
The instrument parameters can be modified by the master. Therefore, from the
instrument front the parameters can be only displayed but not modified.
7. Lock/Unlock Operative Parameters
The modification of the operative parameters can be protected (ModBus address 217).
8. Attribute Description
Every variable has one or more of the following attributes:
Attribute Meaning
R The variable is readable
W The variable is writable (some restrictions may occur)
D The variable is linked to another variable for decimal point
M The variable is linked to another variable for multiplier
