IEC 870-5-101
IEC 870-5-101 is a serial polling-type communication protocol used by Master-Slave application.
When RipEX radio network run in Router mode, more IEC 870-5-101 Masters can be used within
one Radio network and one Slave can be polled by more Masters.
IEC 870-5-101 protocol configuration is using all parameters described in
On, Off only. Protocol broadcast address is not configurable, it is defined by Address
mode in Advance parameter (default 0xFF)
Advanced parameters
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 address is 0xFFFF.
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.
