Analog outputs
The module has two analog outputs. These can optionally be assigned parameters as
voltage or current output.
NOTICE
The analog outputs are only enabled following the parameter assignment.
From the switch-on of the I/O module to its enabling, the analog outputs do not read 0 V,
but are defined by a voltage pulse at -0.2 V. This value must be taken into consideration
when specifying the setpoint value.
The cycle time of the analog value accumulation is limited by the PLC cycle.
