  • Page 21: Functional Overview

    Functional Overview Functions The ASi Master Module is compliant to AS-interface V2.1 (including V2.0). It allows the use of V2.1 functions shown in Table 3.1, provided the connected slaves are AS- interface V2.1-compliant and support the respective functions. If V2.0-compliant slaves are connected, only V2.0 functions are available.
  • Page 22 Table 3.2 I/O Codes I/O Code I/O Code ID Code Each ASi slave also has an ID code. In AS-interface V2.1, both the I/O code and ID code are used to identify a slave type. A slave with ID code $A has Extended Code ID1 and Extended Code ID2.

  • Page 23: Operating Mode

    Indicates that the module is operating normally in Protected mode. The ASI Master Module should normally be in online mode. If it stays in offline mode for whatever reason, please contact Yokogawa. The following table shows the LED display for each mode.
  • Page 24 Configuration Mode (MST LED blinks) MODE PRO- TECT Mode switch CONFIG ASi+ ASi- Figure 3.2 Mode Selector Switch The Configuration mode is used during startup preparation, when slave information (address, I/O code, ID code) are read over the ASi line, and registered to the list of projected slaves in the F3LA01-0N module.
  • Page 25 Lock Function The Lock function is used to prevent inadvertent switching from Protected mode to Configuration mode. If the MODE switch is accidentally turned from the PROTECT position to the CONFIG position in locked state, the module remains in Protected mode. At the same time, both the MST and NST lamps enter fast-blinking state to indicate an invalid switch position.
