REMOTE PROGRAMMING
7.5.3 DIGITAL I/O
 This interface provides 8 opto-isolated logic inputs and 8
opto-isolated logic open drain outputs.
 All in- and outputs have a common zero.
 See datasheet and manual of the INT MOD DIG for more
information.
7.5.4 ISOLATED CONTACTS
 On this interface, there are 4 floating relay contacts available
that can be controlled by Ethernet commands.
 This can be used to trigger an external safety alarm or to
interact in automated processes.
 Floating Interlock connector (standard Interlock is at the level
of Safety Earth).
 Floating Enable input to switch the output On/Off (24Vdc).
 See datasheet and manual of the INT MOD CON for more
information.
Note: the floating relay contacts can not be controlled by the
sequencer.
7.5.5 SIMULATION
 With this interface it is possible to perform several
simulations.
 One of these simulation modes is photovoltaic simulation
based upon user variables.
 Other simulation modes are internal resistance, leadless
sensing and fold current simulation.
 All modes are easy configurable through the web interface.
 Note1: simulation interface can NOT be inserted in slot1.
 Note2: maximum 1 simulation interface possible per unit.
 Note3: this interface cannot be combined with a master slave
interface.
 See datasheet and manual of the IND MOD SIM for more
information.
7.5.6 MASTER / SLAVE CONTROL
 The resulting combination behaves like one power supply and
can be manually controlled or programmed on the master.
 Mixed parallel - series operation is also possible.
 Note1: maximum 1 master slave interface possible per unit.
 Note2: this interface cannot be combined with a simulation
interface.
 See datasheet and manual of the IND MOD M/S for more
information.
