4.3.8.1 Socket tray
The socket tray helps to select the appropriate tightening program depending on the tool used (socket).
For control, there are two types of socket tray:
• Bit pattern coding (multiple sockets can be simultaneously displayed for removal).
• Decimal coding (only one socket can be displayed for removal; instead, a larger number of sockets
can be managed).
Fig. 4–33: Example of an 8x socket tray
By connecting to a 24V interface (IM24V in the tightening controller), the appropriate input signal will be
set at the PLC interface. The value of the input signal depends on the tool removed from the socket tray.
Here, the four inputs
0.0 to 0.3 are used as a 4-bit word. Program selection can thus take place by
assigning the program selection bits Prog0 to Prog3 in the PLC table.
For job functionality, Haller & Erne socket trays of the series MSTKN-X-XXX-XX-DB25M and MSTKN-X-
XXX-XX-DB25M-OP are supported.
