If an IOWR- or IORD-instruction is used during operation, comparison will stop
during instruction execution. Care must be taken, therefore, with the timing of
executing instructions. (Refer to 3-5 "Output Control" for details.)

Note 1. The Counter Inputs (A, B, Z) are insulated from each other and from the Digital
Inputs. The Digital Inputs are also insulated from each other. All Counter Inputs
and Digital Inputs are reverse polarity protected and insulated from the I/O-bus.
2. A noise filter can be configured (10 kHz or 50 kHz (default)) for the Digital
Inputs. Every Z-Input has a defined noise filter of 1 kHz.
3. If the 50-kHz noise filter is configured for External Control Inputs, signals of
10 µs or longer can be read.
