RP570
RP570 is a serial polling-type communication protocol used in Master–Slave applications.
Multiple RP570 Masters can be used within one network and one Slave can be polled by more than
one Master.
Underlined parameters are described in Common parameters .
Mode of Connected device
Master
• Local simulation RB
List box: Off, On
Default = Off
The RP570 protocol Master very often transmits the RB packets (hold packets) solely to check
whether Slaves are connected. In order to minimize the mobile network payload, the Unit can be
configured to respond to these packets locally and not to transmit them to the Slaves over the mobile
network.
If On , the Unit responds to RB packets received from the RP 570 master locally over the COM in-
terface. However from time to time (RB period) the RB packets are transferred over the network in
order to check whether the respective Slave is still on. When the RB response from the Slave to
this RB packet is not received over the mobile network within the set RB timeout, i.e. the respective
Slave is out of order, the central Unit stops local answering to RB packets from the master for the
respective Slave.
• RB Net period [s]
Default = 10
The M!DGE/MG102i/RipEX responds to the RB packets locally and in the set RB period the RB
packets are transferred over the network.
• RB Net timeout [s]
Default = 10 (maximum=8190)
Whenever an RB packet is sent over the network, the set RB Net timeout starts. When the RB re-
sponse from the remote unit (Slave) is not received within the timeout, i.e. the respective Slave is
out of order, the central Unit stops the local answering to RB packets from the master for the re-
spective Slave.
