  2. U ASI ASI ACTIVE POWER ADDRESS/ERROR FX2N-32ASI-M MODE SET PRJ MODE PRG ENABLE FROM/TO CONFIG ERR FX2N-32ASI-M / Specification Item Description Maximum Number of Max. 31 slave units Controllable Units (up to 4 inputs and outputs per slave address) I/O Refresh Time Max. 5ms (connecting maximum I/O points) Communication Speed 167kbps Communication Method APM (Alternating Pulse Modulation) Network Type Bus network type (Free topology) Total Extension Distance Max 100 m ( ext. up 300 m with 2 repeaters) Number of Occupied 8 points taken from the programmable I/O Points controller bus (can be either input or output) Applicable Programmable FX2N Series, FX0N Series controller (Total system I/O points: 256 or less) Communication with FROM / TO instruction Programmable Controller Display (7 Segment) 2 column (slave address / error code)

  3. Item Description Power Lit when 5V DC power supplied from main unit U ASI ASI ACTIVE U ASI Lit when external power supplied from the ASI Power supply ASI ACTIVE Lit when ASI system is in normal operation mode POWER ADDRESS/ERROR PRJ MODE Lit when 32ASI-M is in configuration mode PRJ ENABLE Lit when 32ASI-M is in automatic address programming enable FROM / TO Lit when 32ASI-M is accessed from main unit FX2N-32ASI-M CONFIG ERR Lit when ASI system has a configuration error MODE SET PRJ MODE PRG ENABLE FROM/TO CONFIG ERR Item Description MODE Used to switch between “Protected Operation Mode” and “Configuration Mode” SET Used to Set or delete the slaves address LED Indication / MODE,SET button

  4. Master Start-Up - No data communication on the AS-Interface. If AS-Interface is not sufficiently powered “U ASI” LED is not lit, the master remains in off-line phase. <40> Offline Phase - The ASI remains in detection phase until it finds at least one slave or if two slave have double addressing. <41> Detection Phase - Activates the slave(s) which 32ASI-M found in the detection phase. This enables access to the AS-Interface slaves data connection. <42> Activation Phase - The 32ASI-M can exchange data with all active slaves. It transmits management messages and looks for and activates newly connected slaves. - Normal operation mode contains the “Protec- ted mode” and the Configuration Mode. <43> Start of Normal Operation < No display > Protected Oper. Mode < Detect. Slaves> Configuration Mode

  5. U ASI ASI ACTIVE POWER ADDRESS/ERROR FX2N-32ASI-M MODE SET PRJ MODE PRG ENABLE FROM/TO CONFIG ERR Configuration MODE and Protected Operating Mode The Mode can be changed by: - operating the switch on the 32ASI-M - or by setting BFM #0 (bit 2,3) The switch on the 32-ASI can be disabled to prevent mis-operation - the mode can still be changed by a command from the PLC - the disabled switch can be operate when the 32ASI-M is in “Offline-Phase”

  6. U ASI ASI ACTIVE POWER ADDRESS/ERROR FX2N-32ASI-M MODE SET PRJ MODE PRG ENABLE FROM/TO CONFIG ERR Configuration MODE and Protected Operating Mode Switching to “Configuration Mode” by MODE button - Press “MODE” button more than 5 seconds Switching to “Protected Operation Mode” by MODE button - Press “MODE” button less than 5 seconds - 32ASI-M exits the configuration mode without copying the configuration to setpoint configuration. - Press “MODE” button more than 5 seconds - 32ASI-M exits the configuration mode and copying the configuration to setpoint configuration. 32ASI-M stores this configuration into the List of Projected Slaves (LPS), and stores the actual parameter to permanent configuration.

  7. U ASI ASI ACTIVE POWER ADDRESS/ERROR FX2N-32ASI-M MODE SET PRJ MODE PRG ENABLE FROM/TO CONFIG ERR Configuration MODE Set the slave address number: - The green “PRJ MODE LED” lights up - For active slave - all recognised slave are activated with exception of slave 0 - Displayed message - 32ASI-Master displays all slaves entered in the list of detected slave (LDS) at speed two per second.

  8. U ASI ASI ACTIVE POWER ADDRESS/ERROR FX2N-32ASI-M MODE SET PRJ MODE PRG ENABLE FROM/TO CONFIG ERR Configuration MODE (setting the slaves address) This operation assign an available address to slave with address 0. - The address of all recognised slaves are displayed one after the other - Press “SET” button to display next higher available address - Press the “SET” button for more than 5 seconds - The address displays blinks - Press the “SET” button once again - If error code did not display, the screen displays the list of detected slaves

  9. U ASI ASI ACTIVE POWER ADDRESS/ERROR FX2N-32ASI-M MODE SET PRJ MODE PRG ENABLE FROM/TO CONFIG ERR Configuration MODE (deleting the slaves address) This operation assign address 0 to a recognised slave. - The address of all recognised slaves are displayed one after the other - Pressing “SET” button for more than 5 seconds while the address which wants to be deleted displayed, this slave is reprogrammed to address 0 - When releasing the “SET” button, the display continue to display the list of detected slave (LDS)

  10. Protected Operation Mode In the Protected Operation Mode the 32ASI-M is in data exchange with the projected slaves - For active slave - Only slaves that are entered on the List of projected slaves (LPS) and whose actual configuration match the setpoint configurations will be activated. - Display message - The display is either blank or displays the address of faulty assignment. U ASI ASI ACTIVE POWER ADDRESS/ERROR FX2N-32ASI-M MODE SET PRJ MODE PRG ENABLE FROM/TO CONFIG ERR

  11. Automatic Address Assignment U ASI ASI ACTIVE A slave with address 0 will be automatically assigned with the operating address. - Following requirements are necessary: - The 32ASI-M is in protected operation mode - The automatic address assignment is allowed - Only one of the slaves is not recognized POWER ADDRESS/ERROR FX2N-32ASI-M MODE SET PRJ MODE PRG ENABLE FROM/TO CONFIG ERR

  21. Command Buffer <BFM 20 to 22> (1) By using the Command Buffer, programmable controller is able to instruct the 32ASI-M. Command Word Description Using location 0 No command Writes data word 0 (BFM #21) to the actual parameter in the AS-Interface slave n (n = “Command Word”). And reads the actual parameter from AS-Interface n to data word 0 0 to 31 Normal operation 32 No command Reads the actual parameter from AS-Interface slave n ( n = “Command Word” - 32) to data word 0 < default = F (Hex) > Normal operation Off-line phase 33 to 63 64 No command Writes data word 0 to permanent parameter in the AS-Interface slave n ( n = “Command Word -64) Normal operation Off-line phase 65 to 95 96 No command

Mode Off-line phase 256 Store actual AS-Interface configuration. This command copies LAS (BFM #12,#13) to LPS (BFM #14,#15). And store actual configuration to permanent configuration, too. Configuration Mode 257 Store the actual AS-Interface parameters to permanent configuration. Normal operation, Off-line phase 258 Enable or disable the “Mode” and “Set” push buttons Data Word = 0 enable (default) / Data Word = 1 disable Configuration Mode 259 Read list of corrupted slaves from 32ASI-M to data word 0 and 1, and clear this list.
