Determine the connection points
All connections must be programmed with module and point, so
in principle it does not matter where the connections are made, as
long as it takes place on a correct type of input or output.
• The controller is the first module, the next one is 2, etc.
• A point is the two or three terminals belonging to an input or
output (e.g. two terminals for a sensor and three terminals for a
relay).
The preparation of the connection diagram and the subsequent
programming (configuration) should take place at the present
time. It is most easily accomplished by filling in the connection
survey for the relevant modules.

Note
The safety relays should not be fitted onto a module
with override changeovers, as they can be put out of
operation by an incorrect setting.
- Columns 1, 2, 3 and 5 are used for the programming.
- Columns 2 and 4 are used for the connection diagram.
