A4.2.2 Setting Condition Switches
Use the DIP switch (SW1 to SW4) located on the right side of the module to set up the
following functions.
Enabling/Disabling Shutdown Output on Transmission Channel Error
Function
Use SW1 for this setting.
This switch is valid only for subunits.
For the main unit, set the switch to OFF (factory setting is ON).
For details on the Shutdown Output function, see Section A7,
“RAS Functions”

Note
If the module has its Shutdown Output function (Condition Switch No. 1) set to ON, it treats a
transmission channel error due to, say, a broken fiber-optic cable or a powered-off main unit as a major
failure of the sequence CPU module. Thus, if a transmission channel error occurs with Condition
Switch No. 1 set to ON, the output is either shut down or held according to the DIO Setup ("Reset" or
"Hold") of the CPU configuration.
Note
Always set switch numbers 2, 3 and 4 to OFF.
Turning on these switches may affect normal module operation.
