Address mode
Even if IEC 870-5-101 is the standard, there are some users which customized this standard
according their needs. When addressed byte has been moved, RipEX has to read it on the
correct location.
■
IEC101
Address byte location according to IEC 870-5-101 standard.
Broadcast from Master station is generated when address byte is 0xFF.
■
2B ADDR
Two byte address (IEC 870-5-101 standard is 1 Byte). The frame is 1 Byte longer than
standard one. There is Intel sequence of bytes: low byte, high byte. Mask Address translation
has to be used, because Table one is limited just to one byte address length.
Broadcast from Master station is generated when low address byte is 0xFF and high address
byte is 0x00.
■
TELEGYR
The Control byte in standard IEC packet is omitted. The frame is 1 Byte shorter than standard
one. This is typically used in Telegyr 805/809 protocol.
Broadcast from Master station is generated when address byte is 0x00.
■
SINAUT
The sequence of Address byte and Control byte in the frame is changed-over.
Broadcast from Master station is generated when address byte is 0x00.
ITT Flygt
ITT Flygt is a serial polling-type communication protocol used in Master-Slave applications.
ITT Flygt protocol configuration uses all parameters described in
Common parameters
.
Mode of Connected device
Master
Broadcast
Note: There is not a possibility to set the Broadcast address, since ITT
Flygt broadcast messages always have the address 0xFFFF. Hence when
the Broadcast is On, packets with this destination are handled as broad-
casts.
•
First Slave Address
Default = 1
Slave addresses are not defined in the ITT Flygt protocol. However
Slave addresses have to be defined in the RipEX network. This is the
First Slave address in decimal format.
•
Number of Slaves
Default = 1
Since the ITT Flygt protocol Master (centre) polls the Slaves (remotes)
one by one without any addressing, number of slaves has to be defined.
