2) Status display LED RUN, ERR
The RUN and ERR LEDs on the option board display the status of the self station (operation and error).
Since the option itself determines the status as a slave, the status may be different from RUN and ALM
shown on the CPU of MICREX-SX.

Protective Function
er4
: Network failure (SX bus error)
Light alarm
*1: o30 and o31 can be used to control the
er4
alarm.
Heavy alarm
*2: Momentary alarm
arf
: Toggle error
Monitors the 2-bit signals for the toggle signal 1 [TGL1] and toggle signal 2 [TGL2]
sent from PLC, and generates this error if these the specified change pattern cannot be
received within the time specified by H144.
*3
*1 Light alarm: E.g., Signal noise. If the noise is not frequent, the
er4
alarm can be controlled by o30 and o31 to
continue operation.
*2 Heavy alarm: Fatal failure such as hardware failure.
*3 For the details of the toggle signals and toggle error, refer to TGL1 and TGL2 in E01 to E13 toggle signal
explanation in "4.3 Function Code Details".
Note: The data update frequency depends on the carrier frequency setting, MICREX-SX SX bus tact frequency, and
application program task frequency.
