5.14.2. Cyclic data channel for C3T30 and C3T40
An additional communication channel (besides the one established by the Drive
Interface which is not freely assignable) can be established between the programs
of the C3 powerPLmC and a Compax3 axis via a freely usable cyclic data channel.
To do this, the assignment of the channel is defined on the side of the C3
powerPLmC in the controller configuration for the respective axis. The assignment
is always bidirectional.
The following options are available for the communication between the two
programs.
Assignment of the cyclic channel with 2 INT variables
Mapping to Compax3 objects
C3.PLmCToC3_INT1 / C3.PLmCToC3_INT2 from PLmC to Compax3
C3.C3ToPLmC_INT1 / C3.C3ToPLmC_INT2 from Compax3 to PLmC
Mapping to power PLmC variables
"Axis name".PLmCToC3_INT1 from PLmC to Compax3
"Axis name".PLmCToC3_INT2 from PLmC to Compax3
"Axis name".C3ToPLmC_INT1 from Compax3 to PLmC
"Axis name".C3ToPLmC_INT2 from Compax3 to PLmC
Assignment of the cyclic channel with one DINT variable
Mapping to Compax3 objects
C3.PLmCToC3_DINT from PLmC to Compax3
C3.C3ToPLmC_DINT from Compax3 to PLmC
Mapping to power PLmC variables
Axis name".PLmCToC3_DINT from PLmC to Compax3
"Axis name".C3ToPLmC_DINT from Compax3 to PLmC
Assignment of the cyclic channel with one REAL variable
Mapping to Compax3 objects
C3.PLmCToC3_REAL from PLmC to Compax3
C3.C3ToPLmC_REAL from Compax3 to PLmC
Mapping to power PLmC variables
"Axis name".PLmCToC3_REAL from PLmC to Compax3
"Axis name".C3ToPLmC_REAL from Compax3 to PLmC
The use of INT or DINT variables is especially suitable for implementing a user-
defined control word / status word between C3 powerPLmC IEC61131-3 program
and Compax3 IEC61131-3 program.
