(1)
This FB does not contain error recovery processing. As needed, create an error recovery
processing block to suit your system requirements and other needs.
(2)
With this FB, the communication unit may be communicating with the controller until
Execution Status (o_bENO) is turned OFF. While Execution Status (o_bENO) is ON, do not
run any FB other than this on the same communication unit.
(3)
Use this FB as a macro type FB.
(4)
You cannot use this FB in an interrupt program.
(5)
If this FB is used in a run-once program (such as a subroutine program or a FOR ... NEXT
program), it will fail to operate normally due to the inability to turn OFF Execution
Command (i_bEN). For this reason, be sure to use this FB in a program with the ability to
turn OFF Execution Command (i_bEN).
(6)
The Sensor Output (o_u3SensorOutput) and Detected Value (o_d15DetectedValue) used by
this FB are cleared when Execution Command (i_bEN) is turned OFF. All the output labels
are OFF or zero while Execution Status (o_bENO) is OFF. Carefully note this when you turn
ON and OFF Execution Command (i_bEN) and then update the data.
(7)
When executed in CC-Link mode 1 on SC-HG1-C, this FB acquires the Detected Value
(o_d15DetectedValue) for each of the three groups consisting of the master device and slave
devices 1 to 6, slave devices 7 to 13, and slave device 14. Then this FB acquires the Sensor
Output (o_u3SensorOutput) in a batch fashion. Carefully note that, due to the above reason,
executing this FB in CC-Link mode 1 on SC-HG1-C while varying the displacement amount
may cause differences in the relationship between the detected value and output.
(8)
Configure the global label as instructed in "1.4 Global labels".
(9)
This FB uses the index registers Z8 and Z9. Do not use Z8 and Z9 in an interrupt program.
(10) This FB results in an ignorable "double coil" warning because it uses the index register to
operate the remote output (RY).
(11) Do not run this FB on any device other than SC-HG1-C or SC-HG1-CEF.
(12) If you are using two or more CC-Link IE Field master/local modules and want to control the
SC-HG1-C or SC-HG1-CEF connected to each module, create the FBs for use with the
second and subsequent modules as instructed in "Appendix 5 How to Use FBs across two or
more master/local modules ".
