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.
Underlined parameters are described in
•
Address mode
List box: Binary (1 B), Binary (2B LSB first). Binary (2B MSB first).
Default = Binary (1 B)
M!DGE/MG102i/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.
Note 1:
3964(R) protocol uses an escape sequence (control sequence)
for DLE (0x10), i.e. when 0x10 is in user data, 0x1010 is sent instead.
When the address position is calculated, the bytes added by the escape
sequence algorithm are not taken into account.
Note 2:
The first byte in the packet has the sequence number 1, not 0.
•
DLE timeout [ms]
Default = 1000 (min. 300, max. 8190)
M!DGE/MG102i/RipEX expects a response (DLE) from the connected device (RTU) within the set
timeout. If it is not received, the Unit repeats the frame according to the “Retries” setting.
•
Retries [No]
Default = 3 (min. 0, max. 7)
When DLE timeout is „On“, and the DLE packet is not received from the connected device (RTU)
within the set DLE timeout, the Unit retransmits the frame. The number of possible retries is specified.
•
Priority
List box: Low, High
Default = Low
When the equipment sends STX and receives STX instead of DLE, there is a collision, both devices
want to start communication. In such a case, one unit has to have priority. If the Priority is High, the
Unit waits for DLE. When it is Low, the Unit send DLE.
