System variables
System variable Meaning
$C_M_PROG TRUE, if the M function has been programmed
$C_M For $C_M_PROG == TRUE, contains the value of address M
We must differentiate between two cases here:
• $C_M supplies the value if, for the tool change with M
function, a subprogram is configured with parameter transfer:
MD10715 MN_M_NO_FCT_CYCLE
• If only one subprogram is configured for the addresses T
and/or D/DL and if in the program the M function for the tool
change is programmed together with one of the addresses to
be replaced, then $C_M supplies the value: MD22560
$MC_TOOL_CHANGE_M_CODE
$C_AUX_VALUE[0] Value of the replaced M function
$C_ME For $C_M_PROG == TRUE, contains the value of the address
extension of the M function
$C_AUX_EXT[0] Address extension of the M function(identical to $C_ME)
$C_AUX_IS_QUICK[0] TRUE, if the M function was programmed with quick output to the
PLC
$C_T_PROG TRUE, if the T function was programmed
$C_T For $C_T_PROG == TRUE, contains the value of the T function
$C_TE Contains for:
• $C_T_PROG == TRUE
• $C_TS_PROG == TRUE
the value of the address extension of the T function
$C_TS_PROG TRUE, if for the T or TCA replacement, a tool identifier has been
programmed.
$C_TS For $C_TS_PROG == TRUE, contains the tool identifier
programmed for the T or TCA replacement
$C_TCA TRUE, if the TCA replacement is active
$C_DUPLO_PROG TRUE, if the duplo number of the TCA replacement has been
programmed
$C_DUPLO For $C_DUPLO_PROG == TRUE, contains the value of the
programmed duplo number
$C_THNO_PROG TRUE, if the toolholder/spindle number of the TCA replacement
has been programmed
$C_THNO For $C_THNO_PROG == TRUE, contains the value of the
programmed toolholder/spindle number
$C_D_PROG TRUE, if the D function has been programmed
$C_D For $C_D_PROG == TRUE, contains the value of the D function
$C_DL_PROG TRUE, if the DL function was programmed
$C_DL For $C_DL_PROG == TRUE, contains the value of the DL
function
$P_SUB_STAT Block-related time that the replacement subprogram is called
