Parameterizing Via Fieldbus; Procedure - WEST POS-124-U-PFN Technical Documentation Manual

11 Parameterizing via Fieldbus

11.1 Procedure

Preparation:
- Power supply of the different sections has to be available.
- For safety issues the system should not be active.
If active, the ENABLE bit in the control word has to be reset.
Attention: Parameterization via fieldbus can also be done having an active system. In this case it
should be done very carefully because changes are directly operative.
Parameterization:
- At first the PARA MODE bit has to be set to enable parameterizing via Profinet.
This will be reported via the PARA ACTIVE bit.
- Pretend address and new value of the parameter which should be changed.
- Setting the PARA VALID bit to high will transmit the data.
The PARA READY bit will report a successful parameterization.
Attention: A missing para ready bit means parameterization was not done.
Storing:
- Same procedure as parameterizing standard parameters.
- Selecting 2100 as address, written value does not matter (below 60000).
Password protection:
- If a password was set this has to be entered first for enabling parameterization. Procedure is the
same as when parameterizing standard parameters.
- Select 2200 as address and send the password (PASSFB) as value.
- After PARA READY reports success, subsequently parameterizing can be done as long as PARA
MODE stays active. After resetting it password has to be renewed when it gets activated again.
Attention: Even with active PARA MODE mode the device stays ready for operation.
If the password was transferred incorrect three times, the parameterization mode gets locked (re-
ported by deactivated PARA ACTIVE bit). Only restarting the device enables three new attempts for
enabling.
Please note that a storage of the parameterization via the Profinet is limited in the number of writing
cycles. Means it should be done only when necessary.
