Chapter 3: Functions and Terminology
Terms on output are defined as follows in this operation manual.
Output signals
Output signals are signals from CEU5 to PLC/ PC: preset output, Cylinder stop output and BCD
output.
Preset output
This is the output signal sent to PLC/ PC when counts are matched with the
set values. Upper and lower limits can be set in preset output. Output form
can be selected from three types.
Cylinder stop
output This is the output signal sent to PLC/ PC when pulses coming from encoder
do not change for a certain time. This output signal provides better timing
for reading preset output and outputs sent to PLC/ PC.
BCD output This is the output signal of a value indicated on CEU 5 sent to PLC/ PC for
64ms.
Preset output forms
Preset output forms are three types of output in preset output: compare, 1-shot and hold. Refer to
“Preset output forms list” in a following page for details.
Output method
Preset output can be selected from two methods: normal output and binary output. No. 1 through
No. 31 can be stored in preset setting. However, No. 21 through No. 31 can be used only for
binary output.
Normal output Binary output
Features
･
Allocate one output terminal to one preset
number.
･
Divide preset numbers of 1 through 20 into four
blocks, which are called bank 1 through 4
respectively.
･
Preset output is active for a preset number of a
bank selected.
･
Bank can be switched by external signals.

･
Send signals to PLC/ PC to indicate preset
numbers matched with counts by using all the
five output terminals.
･
To obtain information on preset output, output
terminals 1 through 5 need to be checked.
･
This output is active only when cylinder stopped.
Passed points are not outputted.

Application
･
20 types of work can be sorted to Good or No
Good when the types of work are known in
advance.
･
Another equipment can be operated in the timing
of preset output in CEU5.
･
This output can be used for switching preset
output for work group or process.
･
31 types of work can be classified without
external switching.
･
Unknown work types transferred can be classified
into a maximum of 31 types.
