Specifying the Setpoint Value

The control current provided by the I/O module can be directly specified in the
process image (output) via a setpoint value. The current actual value is depicted
by the I/O module in the process image (input) as the value of the current.
The following examples apply to the factory settings!
The control current, in addition to the nominal current and the setpoint value, is also
influenced by the downstream function blocks. In the delivered state, the setpoint value is
generated linearly from the control current. The following formula applies:
control current [mA] = nominal current [mA] * setpoint value / 10000
The setpoint value is specified by the nominal current in 0.01 % per LSB. The
configuration of the function blocks determines which control current actually arises for a
given setpoint value. For ease of explanation, all subsequent references always refer to
this reference case!
