(Block Check Character). 3964(R) handles only the link layer (L2 in OSI model), hence RipEX uses a

similar way to read “SCADA address” as in UNI protocol.

There is a handshake STX(0x02) – DLE(Ox10) on the start of communication and DLE+ETX – DLE

on the end. This handshake is performed by RipEX locally, it is not transferred over the RipEX network.

Communication goes as follows:

LocalRTU -> STX -> LocalRipEX

LocalRipEX -> DLE -> LocalRTU

LocalRTU -> DATA+DLE+ETX+BCC -> LocalRipEX

LocalRipEX -> DATA -> RemoteRipEX*

LocalRipEX -> DLE -> LocalRTU

RemoteRipEX -> STX -> RemoteRTU

RemoteRTU -> DLE -> RemoteRipEX

RemoteRipEX -> DATA+DLE+ETX+BCC -> RemoteRTU

RemoteRTU -> DLE -> RemoteRipEX

* only this packet is transferred over the RipEX network, all the other ones are handled locally.

• Master

○ Address mode

List box {Binary (1 B); Binary (2B LSB first); Binary (2B MSB first)}, default = "Binary (1 B)"

RipEX reads the Protocol address in the format and length set (in Bytes).

○ Address position

Specify the sequence number of the byte, where the Protocol address starts.
