Setpoints from master instruments can be received via FLOW-BUS only.
To prevent damage to the instruments an/or the system(s) they are connected to, be sure to avoid circular references
between devices on the same fieldbus. The FLOW-BUS system does not have a protection mechanism.

The controller output from the master instrument is multiplied by
Slave Factor
/100% to get the slave instrument setpoint.
In systems other than FLOW-BUS via RS485,
Slave Factor
is effective only if
Control Mode
is set to 'Analog slave', and the
analog output signal of the master instrument is redirected to the input of the slave instrument.
Example:
·
master output = 80%
·
Slave Factor
= 50
slave instrument setpoint = 80% x 50%/100% = 40%
