Local simulation RB
List box: Off, On
Default = Off
The RP570 Slave expects to receive RB packets from the Master. When the Local simulation RB
on the Master is On, the RB packets are transferred over the mobile network only in the RB Net
period (see the Master settings). The Local simulation RB has to be set the same (On or Off) on all
sites in the network, i.e. on the master as well as all Slaves.
If
On
, the Unit generates RB packets locally and transmits them over the COM interface in the RB
Request period and expects the RB response for each RB packet from the RP570 Slave within the
RB Response timeout. When the Unit does not receive the response(s) from the RP570 Slave, the
Unit does not respond to the RB packet from the Master, which it receives over the mobile networks.
•
RB Request period [ms]
Default = 200 (maximum=8190)
M!DGE/MG102i/RipEX sends locally RB packets to the connected RTU in the set period.
•
RB Response timeout [ms]
Default = 500 (maximum=8190)
The Unit expects a response to the RB packet within the set timeout. If it is not received, the Unit
does not respond to RB packets from the Master received over the mobile network.
•
RTU address (Hex)
Default = 01
Active only when the Local simulation RB is On. The connected RTU’s address is supposed to be
filled in. This address (0x00-0xFF) is used in the RB packets generated locally in the
M!DGE/MG102i/RipEX and transmitted over the COM.
Siemens 3964(R)
The 3964 protocol is utilized by the Siemens Company as a Point-to-Point connection between two
controllers. Meanwhile it has become an industry standard that can be found on many devices as a
universal communications interface. 3964R is the same as 3964, in addition it only uses BCC (Block
Check Character). 3964(R) handle only the link layer (L2 in OSI model), hence Unit uses a similar way
to read “SCADA address” as in UNI protocol.
There is a handshake STX(0x02) – DLE(Ox10) at the start of communication and DLE+ETX – DLE at
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
