NOTE –
When installing the link, ensure that the low priority is allocated to
one device and the high priority to the other device.
9.2.1.1 Protocol End Identifier DIP Switch
The introduction of a selecting option for the protocol end identifier (DLE
ETX or DLE ETB) for the R500/R500P is necessitated by the varying
end identifiers used by several Siemens-made components:
- the 3964R data transfer controller for the Siemens process computer uses the
DLE ETB identifier for transfer completion sequences.
- the CP524 and CP525 communication processors (interfaced with a Siemens
Simatic controller) use the DLE ETX identifier for both completion sequences
and transfer response message
The BÜP64 protocol, which has been implemented on the BOSCH CL300
and PC600 controllers, transmits the DLE ETX identifier, although it ac-
cepts both end identifiers when messages are being received.
Unlike on any other interface modules, the R500/R500P interface modu-
les enable DIP switch selection of the appropriate end identifier for each
intended mode of communication; the R500/R500P is therefore able to
communicate with all modules!
To enable interfacing with BOSCH controllers, the end identifier DIP
switch (SS3, SS7) is set to OFF (DLE ETX)!
