TRF_RECIPE Instruction

About us
Reminder
This instruction enables you to read or write the cam profiles and to begin the execution of special functions.
Note: The given parameter length of TRF_RECIPE defines a number of words (double or floating) whatever the type of information exchanged.
NOTE: This service is also used to read or write the variable speed controller parameters with the "Real axis" function, (See TRF_RECIPE).
NOTE: Parameter exchanges (READ_PARAM, WRITE_PARAM, SAVE_PARAM, RESTORE_PARAM) cannot be performed at the same time as the TRF_RECIPE instruction.
Syntax of TRF_RECIPE instruction
TRF_RECIPE (IODDT_VAR, length, address %MW): transfers the cam profile parameters from the table of %MW words. The length of this table to be transferred is defined by the length parameter. The action to be carried out is defined by the word %MWr.m.c.10 (ACTION_TRF).
Example: TRF_RECIPE (IODDT_VAR, 100,200) reads the "Slave" table of cam profile 25 of the module located in position 4 of rack 1, then transfers this to the PLC, from address 200. For an IODDT_VAR variable declared as type T_CSY_CAM and associated with channel 25 of module 4 from rack 1.
TRF_RECIPE Interface
The command to be carried out is defined in the word %MWr.m.c.10 and the result of the command is available in the word %MWr.m.c.3 to %MWr.m.c.8.

Legend
Writing the drive into the module
PARAM_TRF_1 = 0. On MW
Writing the module into the drive
PARAM_TRF_1 = 1. On KW
Reading
PARAM_TRF_1 = 0.
