The parameters that can be set for auxiliary outputs 1 to 4 are outlined below.
The settable parameters include those for all channels and those for individual
channels.
SUB1 SUB2
SUB2, SUB3, and SUB4 can be set in the same way.
Settable
parameters
Disabled
Temperature Controller Error
Event inputs 1 to 4
Bus inputs 1 to 3
Temperature The Temperature Controller Error output will turn ON when any
Controller Error bit between bit 0 and bit 13 is ON in the Device A Status. It can
be used to output EJ1 error status.
Refer to Status Lists on page 209 for details on Device A Sta-
tus.
Event inputs 1 to 4 Output the ON/OFF status of event inputs 1 to 4.
Bus inputs 1 to 3 Output the ON/OFF status of bus inputs 1 to 3.
Variable type

Conditions for use No special conditions
(1) This parameter can be set only when operation is stopped.
When this parameter has been changed, the new setting becomes effec-
tive the next time a software reset is performed for the Unit or the next
time power is turned ON.
(2) Refer to Parameter List on page 193 for details on parameter settings.
The EJ1 has three internal device buses. I/O allocations can be made for
these buses, which enables simple sequencing to be incorporated by allocat-
ing output signals to buses (bus output assignments) and determining opera-
tions based on bus status (bus input assignments).
Bus inputs cannot be used if a Basic Unit is used without an HFU.
Even if an HFU is used, bus inputs cannot be used for Basic Units connected
to the RS-485 communications lines using distributed positioning.
