Initialisation of the CAN driver
3.2 Initialisation of the CAN driver
The "LenzeIo1000Drv.lib" function library for the L-force I/O system 1000 is based on a
library for transmitting and receiving CAN objects. Depending on the PLC version, the "CAN
on board" or an optional fieldbus card can be used as communication channel.
9400 ServoPLC
For using the "LenzeCanMsg.lib" library, an initialisation of the CAN driver with L_CanInit
function block call is required. This function block must only be called once. Thus, best use
the "PLC_START" system event for calling this function.
The L_CanInit function block outputs information on the communication channel used via
its dwHandle output. This information must be provided to the blocks of the
"LenzeIo1000Drv.Lib" via the dwHandle input.
Drive PLC, 9300 Servo PLC, ECS
For using the "LenzeCanDrv.lib" library, an initialisation of the CAN driver with the
L_CanInit function call is required. This function must only be called once. Thus, best use
the system POU "PLC_ColdStart" for calling this function.
The L_CanInit function returns information on the communication channel used via the
dwHandle variable. This information must be provided to the blocks of the
"LenzeIo1000Drv.Lib" via the dwHandle input.
