Fig. 8.2-4 Data-traffic channels of the CBP2
When interconnecting connectors, binectors, and double word
connectors, please note that simultaneous interconnection of a
connector, and a double word connector with the same name is not
permitted, because when a double word connector (e. g. KK3032) is
connected, the meanings of the connectors K3002 and K3003 are
swapped round (high-word and low-word exchanged).
On MASTERDRIVES MC and Compact Plus on software version V1.50
and higher and on MASTERDRIVES CUVC on software version V3.23
and higher, simultaneous use of connectors and double word connectors
with the same name is mutually interlocked (see also function diagrams
[121] and [131]).
Because the binectors are not included in the interlocking (to ensure
compatibility for older configurations), their significance changes
according to whether the pertinent word or double word is wired.
Useful data for the cyclical MSCY_C1 channel (see Figs. 8.2-3 and 8.2-
4) is structurally defined in the PROFIBUS profile for variable-speed
drives version 2 as a parameter process data object (PPO).
Frequently, the cyclical MSCY_C1 channel is simply called the
STANDARD channel as well.
