Excerpt from the
basic circuit
diagram
Here you can see the terminals that can be measured (the PLC inputs and outputs are mostly
connected to a strip in the electrical cabinet):
Sliding switch
on I/O module
If the Control-is-ready output on the MC is defective, you can use the Control-is-ready
output of a PLC expansion board for test purposes:
PL 405 B or PL 410 B: X8 / pin16
PL 510, input/output module PLD 16-8: X6 / terminal 8
(The function of this terminal can be set with a sliding switch on the rear side of the I/O
module concerned, setting 1 = "Control is ready“, See “X6: PLC outputs on the PL 510” on
page 27 – 518)
For permanent operation with a different wiring contact the machine tool builder and add
the changes to the circuit diagrams of the machine.
