APPENDIX
MODBUS EXCHANGES TABLE
SFX+NETWORK
This table is available for functions:
- reading n registers (function 03h)
- writing 1 register (function 06h)
- writing n register (function 10h)
remarks:
- A reading at a site which is not indicated returns an undetermined value.
- If an entry request (function 06h or 10h) is made on a non-authorised register in writing or with a non-authorised value, this is ignored and an
exception message is sent back.
- The maximum number of registers per exchange is limited to 125 for the 03h function and to 123 for the 10h function.
- This table is general. Certain sites depend upon the operating functions of the chosen SFX+ configuration.

“DP” Dust removal running order via MODBUS
Enter “1” to request the running
Enter “0” to cancel the request
(run in “OR” with a possible AON input)
Remark: The running mode of this order can be different according the SFX+ programming if a
« DP regulation running » below detailed is used.

Intensive running via MODBUS
Enter “1” for intensive running
Enter “0” to cancel the request
(run in “OR” with a possible AON input)

“Fan” Dust removal running order via MODBUS
Enter “1” to request the running
Enter “0” to cancel the request
(run in “OR” with a possible AON input)
(doing the number “fan stop” cycles if loss of the two running orders “fan” (via MODBUS and AON input)

Request of forced running via MODBUS
Enter “1” to request the forced running
Enter “0” not to ask forced running
(run in “OR” with a possible AON input)
(the SFX+ completes the current cycle, then a whole cycle is executed at each transition « 0 »
→
« 1 ». If
request stay to 1, we stay in forced running)

DP regulation running
Write « 0 » for local DP regulation running (the declogging running is given according DP AON input only,
whatever the DP running order may be via MODBUS)
Write « 1 » for remote DP regulation running (the declogging running is given according the DP order via
MODBUS only, whatever the DP AON input may be)
N.B.: this running mode is accessible according the SFX+ programming (see availability on the notice
appendix)
