Setting PN/CAN LINK to "Operational" with the S7 user program
To enable transmission of data between the S7 controller and the PN/CAN LINK, you must set
the control bit to "1" using the S7 user program. This control bit is cyclically transmitted from
the S7 controller to the PN/CAN LINK as part of the IO data.
Note
In "CANopen Manager" mode, bit 2 must also be set to "1" in the control information
transmitted from the S7-CPU to the PN/CAN LINK. You can find additional information on the
effect of the control bit under Control and status information (Page 46).
