(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)
Executing this FB in CC-Link mode 1 on SC-HG1-C executes the command once 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. Carefully note that SC-HG1-C CC-Link mode 1 does not allow you
to execute controllers belonging to different groups in the same scan timing.
(7)
Configure the global label as instructed in "1.4 Global labels".
(8)
This FB uses the index registers Z8 and Z9. Do not use Z8 and Z9 in an interrupt program.
(9)
This FB results in an ignorable "double coil" warning because it uses the index register to
operate the remote output (RY).
(10) Do not run this FB on any device other than SC-HG1-C or SC-HG1-CEF.
(11) If you are using two or more CC-Link/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 ".
