Coolant and tool-specific functions

Assigning coolant (ShopMill/ShopTurn)
In the tool management of ShopMill/ShopTurn, you can assign coolant and tool-specific
functions to each tool. These are activated when the tool is changed. You assign the coolant
to the corresponding machine functions (M functions) using the following machine data:
MD52230 $MCS_M_CODE_ALL_COOLANTS_OFF
MD52231 $MCS_M_CODE_COOLANT_1_ON
MD52232 $MCS_M_CODE_COOLANT_2_ON
MD52233 $MCS_M_CODE_COOLANT_1_AND_2_ON
Tool-specific functions (ShopMill)
Tool-specific functions 1 ... 4 are intended for other M functions that can be activated for a
tool, for example, third coolant, speed monitoring, tool breakage, etc.
Up to eight M functions can be programmed for the activation or deactivation of the tool-
specific functions. Definition is realized using the following machine data:
MD52281 $MCS_TOOL_MCODE_FUNC_ON[0...3]
= - 1
MD52282 $MCS_TOOL_MCODE_FUNC_OFF[0...3]
= - 1
The M functions for the tool-specific functions are executed by the ShopMill cycles at the tool
change. If the checkbox is activated, the corresponding M code is generated from MD52281.
If the checkbox is not activated, the corresponding M code is generated from MD52282.
If you do not want to automatically execute additional M commands at the tool change, then
set the associated machine data to -1 for the M commands of this tool-specific function. This
also hides the associated fields in the tool list.
The default value of the machine data is -1 so that no M values are output for the
corresponding functions.
Technical procedure
The M functions for the tool-specific functions are generated by the ShopMill cycles in a set
(up to four M commands are possible).
The number and also the sequence of the M commands are dependent on the settings of the
machine data (MD52281 to MD52282) and the programming.
If M functions less than 100 are used, the number and sequence of the M commands has no
significance. They are located in the user PLC in the decoded area (DB21.DBB194 to
DB21.DBB206), independent of the number and the sequence when programming.
