How to scale the frequency of DP840 card
Voted best answer
Digital input: 1-8
Connection of digital channel No.
Frequency channel: 1-8
Connection of frequency channel No.
Pulse count channel: 1-8
Connection of puls counter channel No.
The I/O channel has the UnitStatus of dint or HwStatus data type.
On the Modulebus, the frequency value is by default scaled to 0-100% (corresponds to 0-20000Hz).
On PROFIBUS, the frequency value is presented as the actual frequency (0-20000Hz). This means that the frequency input range for DP840 connected to CI801 or CI840 is fixed at 0-20000 Hz, even though Min and Max scaling properties is altered.
