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. Turning the Mode switch from the CONFIG
position to the SET position for more than 3 seconds switches the module to
Configuration mode. (See description on "Lock Function" below).
In Configuration mode, the module communicates with all detected slaves on the ASi
line. However, if there is any mismatch between data registered in the LPS and slaves
detected on the ASi line, the NST LED lights up, and the CONFIG_OK input relay of the
ASi Master Module turns off.
- Registering Slave Configuration to the LPS
You can register the list of detected slaves (LDS)
*2
to the LPS in Configuration mode. To
perform registration, turn the MODE switch to the SET position for more than 3 seconds
in Configuration mode.
(This is the alternative action described in the subsequent paragraph on “Lock
Function”)
*2: For details on LDS, see Subsection 4.1.3.
The automatic address assignment function is disabled in Configuration mode.
The module will not exit from Configuration mode if a blank slave is connected. Turning
the MODE switch to the PROTECT position when a blank slave is present will cause the
MST and NST lamps to enter fast-blinking state and the ERR lamp to enter blinking
state.
To properly switch to Protected mode, return the MODE switch to the CONFIG position,
remove the blank slave, and then again move the MODE switch to the PROTECT
position.
TIP
- A blank slave refers to a slave with address set to "00".
- The "MST", "NST" and "ERR" lamps are known as the operating status LED indicators.
Protected Mode (MST LED lights up)
Protected mode is the normal operating mode. After registering the configuration of
slaves on the ASi line to the LPS in Configuration mode, turn the MODE switch to the
PROTECT position. The module will enter Protected mode, and operation begins.
In Protected mode, the module communicates only with detected slaves on the ASi line,
whose configuration matches the data registered in the LPS of the module.
