5.1.2
SFT Addressing
SFT version 'S' and later version SFTs, have special means to allow
readdressing of individual SFTs with the same address. These are:
1. A command to poll and identify SFT's with the same address based
on their serial number.
2. A command to change the address of a SFT also based upon serial
number.
Terminology:
• New SFT: software version = 'S' or later
• Old SFT: software version 'N' to 'R'
• Note: SFT version 'M' (1st FAST SFT 1997) will not automatically
address since they have no means to change the address 'on the
fly'
• Spare SFT: SFT has address <0>
• Poll: Polling the internal channel address 0 to 12 to see on which
address any connected SFT responds
• Auto Address: Automatically change the address of a Spare SFT to
the next available address
• Auto Readdress: Automatically readdresses all SFT's from 1 to n
Auto addressing rules:
1. Auto addressing takes place on power-on with a present spare SFT
on address 0.
2. If an SFT is found on address 0, it gets readdressed to the next
available address.
3. If one or more new spare SFT's are found on address 0, they get
readdressed to the next available address.
4. A single SFT on any address > 0 stays at the same address after
addressing.
5. If there are several SFT's occupying the same address, these SFT's
get addressed to the next available address.
6. If an old SFT is found together with new ones on the same address,
the new ones get readdressed, the old one stays at the same address.
Auto readdressing by user command only rules:
The rules are the same as for auto addressing but:
1. All new SFT's get readdressed to 1, 2, 3 … n where the old SFT's
will stay on their current address.
2. SFT's get addressed in the order they are found. Thus, if there is no
conflict and the addresses are 1…n, the final addresses will be the
same as before.
