Controlling/Outputting through Parallel Communication
559
Output signal
Signal
Function
READY0
READY1
ON when it is possible to input STEP signal. READY0 and READY1 correspond to line 0 and line 1,
respectively. When through images are being displayed, the READY signal will turn to OFF, but the
STEP signal is received. During the through display, determine whether or not STEP input is allowed
based on the BUSY signal.
BUSY0
(BUSY)
BUSY signal on line 0. Indicates that line 0 is currently measuring or switching the scene. Do not
input next command to the line 0 while the BUSY 0 signal is ON. Otherwise, on-going processing or
commands that are input will not be performed correctly.
BUSY1
(RUN)
BUSY signal on line 1. RUN signal is output in all modes other than the multi-line random trigger
mode. Indicates that line 1 is currently measuring or switching the scene in the multi-line random
trigger mode. Do not input next command to the line 1 while the BUSY 1 signal is ON. Otherwise,
on-going processing or commands that are input will not be performed correctly.
OR0
OR1
Outputs overall judgement. OR0 and OR1 correspond to line 0 and line 1, respectively. This is
determined when the measurement is completed (BUSY signal ON
→
OFF). Selection of whether
ON occurs during an OK judgement result or NG judgement result can be performed in the
communication specifications settings window.

DO0 to 7
DO8 to 15
Outputs overall judgement. OR0 and OR1 correspond to line 0 and line 1, respectively. This is
determined when the measurement is completed (BUSY signal ON
→
OFF). Selection of whether
ON occurs during an OK judgement result or NG judgement result can be performed in the
communication specifications settings window.

Reference: Setting Communication Specifications (Parallel Interface) (p.540)
GATE0
GATE1
Used to control the loading time of the DO signal to external devices. GATE0 and GATE1 correspond
to line 0 and line 1, respectively. ON for the time required for external devices to securely load the DO
signal. Set the output cycle so that the total output time is shorter than measurement interval (input
interval of STEP signal). GATE signal is output only when the [Parallel judgement output] and
[Parallel data output] are set in the measurement flow, and the output process begins when the signal
passes through the parallel judgement output (parallel data output) point in the flow. Depending on
the setting flow, GATE output may be started when the BUSY signal is ON. Note that the OR signal
and GATE signal do not necessarily operate simultaneously.
STEP0
STEP1
Trigger signal to execute a measurement. STEP0 and STEP1 correspond to line 0 and line 1,
respectively. STEP0 and STEP1 can be input at different times with no restrictions on the order of
input. Perform measurement once synchronous with the STEP signal turning on (OFF
→
ON). Turn
the STEP signal ON for at least 0.5 ms. A noise filter (filter initial setting value: 100 μs) is set in STEP
input.
Important
●
If STEP is input to line 0 and line 1 at exactly the same time, measurement on one side may be delayed by
approximately the time corresponding to the camera image input unit.
About Multiple Image Input Function
The function that enables continuous high speed image input is called the multiple image input function.
The next STEP signal can be received at the point when image input is complete. It is not necessary to
wait until measurement processing is complete. Whether image input is complete or not can be checked
with the status of the READY signal.
In the case of FZ4-11
/H11
where two CPUs are installed, you can use the [Single-line
High-speed mode] function that causes the two CPUs to alternately process measurement to shorten
the shortest takt time
*1
to as much as one half.
*1: The shortest takt time refers to the shortest time over which a STEP can be accepted without generating a
pool of captured images.
