This section is only relevant for you if you have connected
CPI/CP modules to the CPI extension connection.
No te
Do not yet connect the CPV Direct to a higher−order
controller for preparing commissioning.
You will thus avoid addressing faults which may occur in
various field bus systems when address ranges are modi
fied during operation.
1.7.1 Checking the CP strings
Preparations Before commissioning a CPV Direct with CPI extensions, you
should first prepare each individual CPI system for commis
sioning.
Proceed as follows:
1. Check the pneumatic tubing of the valve terminals with
the aid of the manual override (see pneumatics manual).
2. Check the complete electric circuitry of the CPI system.
3. Save the current string assignment of the CPI system as the
nominal assignment, as described in section 1.7.2.
