6. CONNECTION OF I/O UNITS TO
1 All the DOs in the unit are designed to be turned OFF if the Power
Mate i generates a system alarm or if a communication alarm is
generated during communication between the Power Mate i and the
unit. Consider this fully when creating a machine sequence to
ensure that the sequence is fail safe. The DOs are also turned OFF
when the Power Mate i or the unit is turned OFF.
2 When the second group is used as an option, and is removed, a
parameter (No. 1905) must be changed. All the DIs from the
second group become “0”.
3 When an extended unit is used as an option, and is removed, all the
DIs from the extended unit become “0”.
4 The FSSB I/O module on the FSSB line that is nearer the Power
Mate is assumed to be group 1, while the farther one is assumed to
be group 2. If there is only one FSSB I/O module group, it is
assumed to be group 1. (Group 1 cannot be used as an option.)
An additional unit must be connected to a basic unit with a flat cable, as
shown below. The flat cable is 100 mm long.
