Other HFU Functions
5-3-1
Auxiliary Output Allocations
The parameters that can be set for auxiliary outputs 1 to 4 are outlined below.
Note
(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 233 for details on parameter settings.
5-3-2
HFU Internal Buses
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).
Note
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.
Temperature
Controller Error
The Temperature Controller Error output will turn ON when any
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 255 for details on Device A Status.
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.
