(1)
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.
(2)
Use this FB as a macro type FB.
(3)
You cannot use this FB in an interrupt program.
(4)
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).
(5)
Do not execute this FB while requesting the initialization because turning ON Execution
Command (i_bEN) while requesting the initialization results in the error code "200" (in
hexadecimal) even if each input label is set to a correct input value.
(6)
Configure the global label as instructed in "1.4 Global labels".
(7)
This FB uses the index register Z9. Do not use Z9 in an interrupt program.
(8)
This FB results in an ignorable "double coil" warning because it uses the index register to
operate the remote output (RY).
(9)
Do not run this FB on any device other than SC-HG1-C.
(10) Executing this FB on SC-HG1-CEF results in an FB error.
(11) If you are using two or more CC-Link master/local modules and want to control the
SC-HG1-C 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 ".
