Appendix 4 Comparison between CC-Link IE controller network and MELSECNET/H
Appendix 4.5 Precautions for program replacement
APPENDICES
POINT
Using an existing sequence program without change may not be allowed due to
some reason such as link scan time difference between CC-Link IE controller
network and MELSECNET/H.
Be sure to check the operation.
(2) For SEND instruction execution by specifying a logical channel
Logical channel setting is not available for the CC-Link IE controller network module.
Change the logical channel setting to any of channel 1 to 8.
Refer to the following for details on the SEND and RECV instructions.
• Section 9.9 JP/GP.SEND
• Section 9.10 JP/GP.RECV
(a) For SEND instruction execution by specifying a logical channel and a station No.
1) Target station (Station that executes the RECV instruction)
Delete a sequence program part of Logical channel setting (SW0008 to
SW000F).
2) Own station (Station that executes the SEND instruction)
Change Target station channel ((S1)+3) in control data to any of channel 1 to
8.
(b) For SEND instruction execution by specifying a logical channel and all stations.
1) Target station (Station that executes the RECV instruction)
• Set a group No. (
• Delete a sequence program part of Logical channel setting (SW0008 to
SW000F).
• Change the own station channel ((S1)+2) in control data to a channel that
is set for the group.
2) Own station (Station that executes the SEND instruction)
• Change Target station channel ((S1)+3) in control data to any of channel 1
to 8.
• Change Target station No. ((S1)+5) in control data to group specification.
Remark
(1) Logical channel specification of MELSECNET/H
Set logical channels 1 to 64 to target station channels 1 to 8 in advance.
When the SEND instruction is executed by specifying a logical channel and
all stations, only the channels of the logical channel setting can receive the
data.
For details, refer to the following manual.
