Operational principle for record selection
2.6.1
Command records
Orders will be saved in CMMO-ST as parameterised sets of commands. Parameterisation of records is
performed via web server (valve profile) or FCT (valve/binary profile).
Every set contains the required parameters for order processing in accordance with the stipulated type
of record. To address an order, the controlling PLC only needs to transfer the record number to the
output data (record selection).

Record selection via I/O interface
When activating via the I/O interface, the execution of a record differs depending on the open-loop
control profile
–
Valve profile: the record is executed directly when the record number is addressed.
–
Binary profile: the record is executed after addressing the record number with the next START signal.
Record selection via Ethernet interface
Via the Ethernet interface, records can also be started from a PC program. For this, in-depth knowledge
of programming TCP/IP applications is required (

Appendix B.1, Control via Ethernet [CVE])
Record selection with FCT
Single records can be started from the record table for test purposes. Also, records can be compiled in
any order and executed as a sequence (test cycle).
