CC-Link communication
The following explains the accessible range and devices for CC-Link communication.
Accessible range
The accessible range for CC-Link communication includes the own station (the master station or local stations controlled by a
C Controller module), the master station or local stations controlled by other stations (CPU module and C Controller module),
an intelligent device station, and a personal computer on which a CC-Link board is installed.
System configuration
Own station (Master or local station controlled by
C Controller module)
Personal computer
(CC-Link board)
When the own station number is 64, other stations cannot be accessed.
Only the own station can be accessed.
Accessible devices
The devices accessible for communication via a CC-Link module are shown below.
• 'Batch' and 'Random' in the following table indicate as follows:
Batch: Batch write (mdSendEx function), batch read (mdReceiveEx function)
Random: Random write (mdRandWEx function), random read (mdRandREx function), bit set (mdDevSetEx
function), bit reset (mdDevRstEx function), random write by using a label name (mdRandWLabelEx
function), random read by using a label name (mdRandRLabelEx function)
• Bit devices can be accessed by using 'bit set' (mdDevSetEx function) and 'bit reset' (mdDevRstEx function).
• Device extension specifications (digit specification, bit specification and index specification) cannot be used.
Accessing the own station
To access a CC-Link module controlled by a C Controller module, use the method explained in the following section.
Accessing the own station by using CC-Link communication will cause the 'station number/network number error.'
