■Network number and station number for MELSEC data link functions (the mdControl function
and the mdTypeRead function)
Network numbers and station numbers to be specified to the mdControl function or the mdTypeRead function are as follows:
Communication
Bus interface
CC-Link IE Controller Network
CC-Link IE Field Network
MELSECNET/H network
CC-Link
*1 Station number setting for a CC-Link IE Controller Network module, CC-Link IE Field Network module, and MELSECNET/H network
module
Upper
Upper/ Setting item
lower
Upper Network number
Lower Station number,
Group number, or All
stations
Logical station number setting method
Set '0' in the upper byte (network number) of the station number above, and specify a logical station number in the lower byte (station number).
The setting range of the logical station number is 65 (41H) to 239 (EFH).
Set the logical station number with the user program (MELSEC data link functions).
*2 When '0 (0H)' or '125 (7DH)' is specified for the station number, a specified control station of the network, which is specified to the
network number, is accessed. To access the current control station (a station that is actually operating as the control station), specify the
station number from 1 (1H) to 120 (78H).
*3 125 (7DH) is valid when CC-Link IE Field Network master station (station number 0) is specified by using the SEND/RECV function
(mdSendEx (message send function) or mdReceiveEX (message receive function)). To access a master operating station (a station that
is operating as the master station when the submaster function is used), specify the station number from 1 (1H) to 120 (78H).

Upper Network number
Lower Station number
Logical station number setting method
Set '0' in the upper byte (network number) of the station number above, and specify a logical station number in the lower byte (station number).
The setting range of the logical station number is 65 (41H) to 239 (EFH).
Set the logical station number with the user program (MELSEC data link functions).
*5 The station number 64 cannot be specified for CC-Link communication.
In addition, when the station number of the own station is 64, other stations cannot be set. (Only the own station can be accessed.)
Station number specification method
Own station: 255 (FFH)
Other station: 1 (CPU No.1), 2 (CPU No.2), 3 (CPU No.3), 4 (CPU No.4)
Own station: 255 (FFH)
*1,*2
Other station:
Own station: 255 (FFH)
*1,*3
Other station:
Own station: 255 (FFH)
*1,*2
Other station:
Own station: 255 (FFH)
Other stations: 0 (0H) to 63 (3FH), 65 (41H) to 239 (EFH)
Lower
Setting value Description
1 (1H) to 239 (EFH) Set this to specify other stations in the own network or each station on other networks.
• Set this to issue a sending request to any of CC-Link IE Field Network, CC-Link IE
Controller Network, MELSECNET/H network, or MELSECNET/10 network.
1 (1H) to 120 (78H) Set the station number of other stations.
• For MELSECNET/H network, the setting range is from 1 to 64.
• For CC-Link IE Field Network, the setting range is from 0 to 120.
129 (81H) to 160 (A0H) Set the group number 1 to 32.
• For MELSECNET/10 network mode, 129 (81H) to 137 (89H): Group number 1 to 9.
• The group number specification is valid when the SEND function (mdSendEx (message
send function)) is used.
(Cannot be specified if CC-Link IE Field Network is used.)
240 (F0H) Set all stations.
• Specifying all stations is enabled when the SEND function (mdSendEx (message send
function)) is used.
Lower
Setting value Description
0 Set the value for CC-Link.
0 (0H) to 63 (3FH) Set the station number of other stations.
